LegalZoom vs Trust & Will: how they compare in 2026
LegalZoom and Trust & Will meet in online estate planning for consumers: wills and trusts built through a guided interview, with attorney help as an add on and AI features around the edges. LegalZoom also sells business formation and filings. They are hard to separate. Both disclaim liability for AI output. Both draw the same line on training: each bars outside AI models from training on customer content. LegalZoom goes further and says Doc Assist uploads may train its proprietary models. Where they part is narrow. LegalZoom publishes 24 MCP tools that let outside assistants act on its services. Trust & Will states SOC 2 Type II and HIPAA examinations by an independent CPA. Both state plainly that they are not law firms.
Which one fits
Choose LegalZoom if
- Your planning touches a business as well as a household. LegalZoom sells wills, trusts, powers of attorney and prenuptial agreements alongside LLC formation, registered agent service, trademark and copyright filings in one account, and states its limits, such as license lists that exclude tax registrations.
- You would rather start from ChatGPT or Claude than from a website. LegalZoom's published MCP catalog gives outside assistants 24 tools with documented schemas and versions, including document analysis against an attorney curated clause framework and booking an attorney review.
- You want to know what the AI checks against and where it can fail. LegalZoom's free Doc Assist analyzes documents against an attorney curated clause framework, takes text files up to 5 MB for US customers, and says plainly that its summaries may be incomplete or inaccurate.
Choose Trust & Will if
- Your family's documents hold health and financial details, and you want an independent report behind the security claims. Trust & Will states SOC 2 Type II and HIPAA examinations resulting in an independent CPA's report, with AES 256 encryption at rest, TLS 1.2 in transit and AWS hosting.
- You want a flat price for a trust with an attorney available. Trust & Will publishes the Will Plan from $199, the Trust Plan from $499, Attorney Support with a licensed attorney in your state for a flat $299 and a membership at $49 a year, and names the states where Attorney Support is unavailable.
- You are an estate attorney or financial advisor rather than a consumer. Trust & Will's EstateOS gives attorneys AI document extraction, estate plan summaries that can be edited before sharing and an AI assistant for client plans and referrals, and publishes flat annual plans for advisors.
At a glance
All 15 axes, side by side
The same grid applied to every vendor in the index, graded from public sources. Hover a grade to see what the letter means on that axis.
AI Centrality
How much of the product is actually AI. Whether the machine learning is the mechanism the buyer is paying for or a feature layered onto conventional software, and whether the vendor is specific about which is which.
The AI is a feature layer on a business whose value stands without it. LegalZoom's AI features are Doc Assist, a free document summarizer; a business name generator, NAICS code search, expense categorizer, grant finder and search summaries; and AI research that produces most business license lists. The core products, such as entity formation and compliance filings, registered agent service, trademark and copyright filings, legal forms and attorney plans, run without the models.
Consumers build wills and trusts through a guided interview that does not depend on models. AI appears in the annual subscription's answers and plan recommendations, and in the attorney and adviser portals as document extraction, estate plan summaries and an AI assistant.
Citation Accuracy and Hallucination Disclosure
Whether the vendor publishes measured accuracy on citations and assertions, grounds output to primary sources, and says plainly what its system does when it does not know. Legal has a documented public record of fabricated citations reaching filed briefs, so an untested claim of accuracy is not evidence.
Grounding is claimed without sources a user can open or any measurement. The MCP catalog says documents are analyzed against a clause framework curated by attorneys, and Doc Assist gives clause highlights and common questions for the document type. The Doc Assist page and FAQ say summaries may be incomplete or inaccurate because they rely on rapidly evolving generative AI, and the AI Additional Terms make no promise that output is accurate. No accuracy figure, test or source linking is published.
The home, Attorneys, Advisors and Compare pages publish nothing on the accuracy of AI answers, extractions or summaries, and the terms warn that AI output may not be accurate.
Autonomy and Oversight Model
What the system decides on its own, what a lawyer must approve, and whether the vendor documents where the review point sits. A tool that drafts under review and a tool that files without one are different products and different risks.
Oversight is asserted through disclaimers and an optional attorney, without a described control on the AI. Doc Assist says its output is informational only and links to attorney review, and the AI Additional Terms say the AI Services do not provide legal advice. A March 2026 release says AI now completes about 70 percent of business license research requests and the rest still go to human review. It does not say what sends a request to a person or who that reviewer is. No lawyer reviews AI output by default.
Estate plan summaries generated by AI can be edited before sharing, and the terms place responsibility for input and reliance on the user. No step requires a person to check an AI answer given to a consumer, and no limit is set on what the AI assistant may do.
Operational and Outcome Evidence
Named, dated evidence that the product works in production at real firms or legal departments. Case studies with figures and identified customers count. Unattributed testimonials and launch announcements do not.
Results are quoted without customer attribution or a method on the customer side. The business license release estimates about $3 million in LegalZoom's own savings in 2026 from automating license research, and a 2023 release says 85 percent of LegalZoom customers had not spoken to an attorney. These are the vendor's operating figures, not named customer outcomes, and the Terms say published reviews carry only a first name and last initial.
The site cites reviews from members identified by first name, adviser results such as assets under management identified and revenue generated, and more than 20,000 advisers using the platform. No named law firm or attorney customer with measured results is published.
Privilege and Confidentiality Posture
How client confidences are handled: attorney client privilege and work product treatment, segregation of one client matter from another, whether client data trains any model, and what the vendor commits to in writing rather than in marketing.
Confidentiality is asserted in general terms, and training use is permitted by policy. The Terms of Service say no attorney client relationship or privilege is created with LegalZoom, and the AI Additional Terms say the AI Services are not meant for privileged or highly sensitive information. The privacy policy says LegalZoom does not intend to collect attorney information in a way that waives privilege. The Doc Assist FAQ says uploads are stored in the user's documents center and may be used to train LegalZoom's own models but not third party AI tools. Nothing addresses separation between users or what an AI provider retains.
External models are barred from training on estate plan and account content, while AI output may be used to improve the services, and nothing covers the company's own models. The security page describes encryption and independent examinations. Privilege and confidentiality for attorneys' client files uploaded to the platform are not addressed.
UPL and Professional Responsibility Posture
Whether the vendor is clear that it supplies a tool rather than legal advice, who its audience is, and how it addresses unauthorized practice of law, competence and supervision duties, and jurisdiction limits. ABA Formal Opinion 512 is the reference point. Where the advice line is not the duty a product raises, the axis is read through the nearest professional duty it does raise: judicial conduct rules and the reviewing duty for products sold only to courts, and the duty to bill for time actually spent for products that draft time entries.
The vendor states plainly what the product is and is not, who may use it and what it requires of its attorneys, with jurisdiction statements and a disclosure on every page. The Terms of Service open by saying LegalZoom is not a law firm, its forms are no substitute for an attorney, the customer represents themselves, and no attorney client relationship or privilege is created. They add that a customer who believes they received legal advice should not buy. The Terms of Use say LegalZoom reviews answers only for completeness and consistency and never applies law to facts. They define network attorneys' experience as five years' practice, errors and omissions insurance, good standing and no recent discipline. The Terms say LegalZoom is not a registered legal document assistant under California law, and the AI Additional Terms limit AI use to adults and say it is not legal advice. The footer names the subsidiary law firm, LZ Legal Services, LLC, as the only route to advice.
Every page carries a notice that Trust & Will is an online service providing legal forms and information, is not a law firm, does not give legal advice and is no substitute for an attorney. The Terms of Service say the same and limit use to adults. Consumers can add Attorney Support at a flat fee, with a licensed attorney in their state and the states where it is unavailable named, or choose an Attorney Led Plan. Documents are described as specific to each state and built by estate planning attorneys.
AI Governance and Bias Disclosure
Published governance over model behavior: who owns it inside the vendor, what is tested before release, and what is disclosed about disparate output across matter types, parties, or populations.
No AI governance position is published. The privacy policy says LegalZoom applies privacy by design, has privacy and security teams, and uses AI and human review in processing; the AI Additional Terms set rules for users. Nothing describes how the AI features are tested before release, who is accountable for them, or how they perform across users or document types.
The main site pages, the Terms of Service and the Privacy Policy publish no AI governance framework, accountable owner, testing before release, or finding on how AI answers or summaries perform.
AI Safety and Data Stewardship
Retention, deletion, access control, and what happens to prompts and documents after they are processed. Whether the vendor states its subprocessors and its incident practice, or leaves the buyer to assume.
The privacy policy covers products as well as the website and lists the data collected. It names payment, shipping and identity verification vendors (WorldPay, Adyen, Stripe, Onfido, Veriff, FedEx, USPS), bars service providers from other uses, sets out access and deletion requests with an appeal route, and says multi factor authentication is in place for all customer accounts. The security page describes a dedicated security team, encryption of sensitive information and a responsible disclosure policy, and the Doc Assist FAQ says uploads are stored in the user's documents center. Retention is only at least as long as necessary, no AI provider is named, and no breach notification commitment is published.
The security page describes AES-256 encryption at rest, TLS 1.2 in transit, AWS hosting and automatic session logouts, and says customers own their data. The Privacy Policy has a section headed Retention of your data. No subprocessor list or incident notification commitment is published.
AI Liability and Recourse
What the vendor stands behind contractually when its output is wrong. Indemnities, caps, carve outs, insurance, and whether any of it is published or only reachable through a negotiated agreement.
Liability is addressed only by disclaimers and a standard cap. The AI Additional Terms provide the AI Services as is, with no promise that output is accurate, complete or fit for use. The Terms of Service and Terms of Use exclude indirect damages and cap liability at the amount paid. The LZ Guarantee is a refund policy on purchases and does not reach the free AI features.
The Terms of Service exclude liability for any direct, indirect or other damages arising from use of the services, subject AI output to the general disclaimers, and require disputes to go to mandatory arbitration with a class action waiver. No warranty or remedy covers a document or AI answer that proves wrong.
Practice Systems Integration Depth
How deeply the product reaches into the systems legal work already lives in: document management such as iManage and NetDocuments, Word and Outlook, contract lifecycle management, matter management, e-billing, and court filing systems.
Documented, verifiable integrations, with what each one does described. The AI capabilities page publishes 24 MCP tools in seven families, from LLC formation and business licenses to document analysis and attorney booking, each with its own page. It also publishes a catalog.json with schemas, annotations, versions and authentication, a text catalog for agents, connector setup documentation and six read only WebMCP browser tools. Named integrations cover ChatGPT, Claude and a Microsoft 365 Copilot agent. For a small business buyer, these assistants and Microsoft 365 are where the work happens.
The attorney platform supports bulk document uploads and referral tracking, and advisers can upload client documents for AI summaries. The attorney and adviser pages name no connection to an attorney's practice management, document management or drafting system.
Deployment Model and Data Residency
Where the software runs and where the data sits. Multi tenant cloud, single tenant, private deployment, on premises, and whether region of residence is a published option or an enterprise conversation.
Cloud delivery is implied, and neither hosting location nor tenancy is stated. The privacy policy covers US, EU and UK users but says nothing about where data is hosted or processed. The Doc Assist FAQ says the service is available only to US customers, which concerns eligibility rather than residency.
Amazon Web Services hosts the platform, and the security page describes AWS components with encryption at rest and in transit. No hosting region, tenancy model or processing location for AI features is given.
Security Certifications and Trust Center
Independent attestation a buyer can pull without a sales call: SOC 2, ISO 27001, penetration test summaries, a trust center with current reports and named scope rather than a badge image.
No independent security attestation is published. The security page, titled a trust page, describes a dedicated information security team, encryption, multi factor authentication and a responsible disclosure policy, and names no SOC 2 report, ISO certification or audit.
The security page says Trust & Will has undergone SOC 2 Type II and HIPAA examinations resulting in an independent CPA's report. No auditor, period, trust center or way to obtain the report is published.
Model Supply Chain Disclosure
Which models sit underneath, whose they are, where they run, and whether the vendor commits to telling customers when that changes. A legal buyer inherits every dependency it cannot see.
Proprietary models are mentioned without saying what sits underneath. The Doc Assist FAQ says inputs may train LegalZoom's own proprietary AI models and will not train third party AI tools, and the AI Additional Terms say the features use generative AI. No model, version or provider is named, and nothing commits to notice of changes. The ChatGPT, Claude and Microsoft 365 Copilot integrations run LegalZoom tools inside other vendors' assistants and do not disclose what powers LegalZoom's own features.
Per the Terms of Service, the AI features may use external models or AI software tools. No model, provider, inference location or change notification is named.
Commercial Transparency
Whether a buyer can learn what this costs without entering a sales process: published rates, the unit being charged, what sits behind an enterprise tier, and what implementation adds.
A buyer can learn the price without a sales process. LegalZoom's own pages publish LLC formation at $0 (Basic), $249 (Pro) and $299 (Premium), each plus state filing fees. Premium's attorney consultations renew at $49 a month after 30 days, bookkeeping tools cost $9.99 a month after six months, and Doc Assist is free. The Terms of Service set out filing fees, a 60 day refund window and an installment plan for purchases of $200 or more.
The Compare page lists the consumer plans, the Attorney Support fee and the annual subscription, and the Advisors page lists flat annual adviser plans. The Attorney Led Plan carries no listed price, and the attorney platform has no published price.
Firm and Practice Coverage
Who the product is actually built for. AmLaw, midlaw, small firm and solo, in house departments, government and courts, and which practice areas are supported rather than merely claimed.
Who the product serves and what it covers are documented, with limits stated. LegalZoom serves small businesses and individuals across business formation and compliance, business licenses, trademarks, copyrights and provisional patents, wills, trusts, powers of attorney, prenuptial agreements, divorce and real estate documents. The stated limits are specific. Doc Assist is for US users only and takes text files up to 5 MB, license lists exclude tax registrations and professional licenses, and the AI features are not for privileged, highly sensitive or minors' information. The Terms say LegalZoom is not a registered legal document assistant in California. Firm segments and government use do not apply to a consumer product.
The site addresses consumers planning wills, trusts, guardianship and probate, estate planning attorneys, financial advisers and nonprofits, and Attorney Support is not available in some named states. Which document types or family situations the online plans do not handle is not stated.
The 12 legal signals, side by side
Recorded rather than graded. These are the questions a practitioner has to answer before a tool touches a client matter, and the answers are taken from public material only.
Client Data in Training
Can material a lawyer puts into this product be used to train a model?
Public material states that customer inputs may train the vendor's own models, with no matching term in the agreement. The Doc Assist FAQ says information provided through Doc Assist may be used to improve the product, which may involve training LegalZoom's own proprietary AI models, and will not be used to train any third-party AI tools. The Terms of Use license personal information only to enable the service and incorporate the Privacy Policy, whose product-development purpose covers developing machine learning or AI technologies without naming training. No opt-out is offered.
The Terms of Service bar training external AI models on estate plan or account content, and reserve the use of content generated through AI features to provide, maintain, develop and improve the services. The terms do not address training Trust & Will's own models, and the improvement right does not name training.
Prompt and Output Retention
How long does the product keep what a lawyer typed, and can that be set to zero?
Retention is acknowledged without a period. The privacy policy says personal information is kept at least as long as needed for its purposes and legal obligations; the Doc Assist FAQ says uploaded documents are stored in the user's documents center and summaries in a LegalZoom database. Deletion is by verified request and may be declined.
The Privacy Policy has a section headed Retention of your data. The security page and the Terms of Service state no retention period for documents, AI inputs or outputs.
Ethical Walls and Matter Segregation
Does retrieval respect the firm’s ethical walls, or can the model read across them?
Controls on account access are the only separation described, and keeping one user's matters apart from another's goes entirely unmentioned. Nothing addresses separation between users' matters beyond controls on authorized contacts for account access.
The Attorneys, Advisors and Security pages describe no separation of client files between matters or users within an attorney's or adviser's account.
Third Party Request and Subpoena Notice
If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?
The privacy policy says personal information may be disclosed as required by law, including subpoenas and law enforcement or national security requests, and the Terms of Service say that for a disabled account no information is released outside LegalZoom absent a subpoena or court order. Neither commits to telling the customer first.
Neither the Terms of Service nor the Privacy Policy outside its retention section addresses court or government requests for customer data.
Primary Law Corpus Provenance
Where does the law in this product come from, and does the vendor have the right to use it?
The sources are identified as the vendor's own content, with no primary law named. The MCP catalog says document analysis uses an attorney-curated clause framework and knowledge search draws on LegalZoom articles and approved legal education; the Terms of Use say LegalZoom strives to keep its documents current but cannot guarantee it. The statutes and cases behind that content and any update cadence are not stated.
The home, Compare and Attorney Support pages say attorneys built the documents and identify no source for the law or forms behind them, or for the material behind AI answers.
Good Law Verification
Does the product tell you when the authority it just cited has been overruled?
A citator would have nothing to check in the summaries and analyses the AI features produce. The AI features summarize and analyze documents and cite no legal authority; no good-law check is described.
The product does not cite legal authority, and nothing addresses checking authority for later treatment.
Refusal and Uncertainty Behavior
What does the product do when the answer is not in the corpus?
Inaccuracy is acknowledged and human review absorbs part of the workload, but the AI itself has no described way of signaling what it cannot answer. Doc Assist says its summaries may be incomplete or inaccurate and points users to attorneys, and the release says about 30 percent of license research requests still go to human review, but no behavior for questions the AI cannot answer, and no confidence signal, is described.
The main site pages and terms do not describe what the AI answers or assistant do when a question needs an attorney or cannot be answered. Attorney Support is sold separately.
Fabricated Citation Record
Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?
The AI Hallucination Cases database kept by Damien Charlotin holds no entry naming LegalZoom or Doc Assist as the tool used. Doc Assist is LegalZoom's AI feature for working on legal documents.
The AI Hallucination Cases database kept by Damien Charlotin holds no entry naming Trust & Will.
Bar Guidance Alignment
Has the vendor engaged in public with the ethics opinions its buyers are bound by?
Professional responsibility is addressed in general terms without named guidance. The Terms set out that LegalZoom is not a law firm, is not a registered legal document assistant under California law, and define the experience standard for network attorneys; the footer names its subsidiary law firm. No ethics opinion, court AI order or bar guidance on AI is named on the surfaces read.
The Attorneys, Attorney Support and Security pages and the terms address no professional obligation for attorneys using the platform's AI and name no ethics opinion.
Billing and Fee Posture
Does the vendor address what happens to the bill when the work takes an hour instead of six?
The product sits outside a lawyer and client fee relationship. Small businesses and individuals buy forms, filings and the free AI tools for their own matters and represent themselves, under the Terms of Service. Attorney fees under the legal plans are governed separately and fall outside this assessment.
Consumers buy their own will or trust plan directly at published prices, outside any fee relationship with a lawyer; optional Attorney Support is a flat fee paid to Trust & Will. The attorney platform's effect on attorneys' fees is not addressed.
Outside Counsel Guideline Readiness
Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?
A customer asking which AI providers handle its documents would find the question unanswered by any list. The privacy policy names payment, shipping and identity-verification vendors as examples, but no subprocessor or AI model provider list is published and none is offered on request.
The Security page, the Terms of Service and the Privacy Policy give no subprocessor or model provider list and no disclosure material for clients.
Court Disclosure Support
If a judge’s standing order requires an AI disclosure, can the product produce one?
Customers who file what they prepare get no guidance on disclosing AI use. Customers prepare documents they may file, such as divorce papers, but nothing addresses disclosing AI use to a court or recording which content AI produced.
The products produce estate planning documents rather than court filings, and the estate planning pages do not address recording or disclosing AI use. Trust & Will also sells a separate probate service.
The questions both sides leave open

Questions buyers ask
LegalZoom vs Trust & Will: which is better for a will or trust?
They are hard to separate. Trust & Will is the specialist, with estate planning at its center, a flat fee attorney add on and SOC 2 Type II and HIPAA examinations. LegalZoom covers estate planning alongside business formation and trademarks, and connects to outside AI assistants through published MCP tools. Neither is a law firm, and both publish their prices. From the AI Legal Index, based on each vendor's own published materials as of September 25, 2026. No vendor pays for placement.
How much does Trust & Will cost compared with LegalZoom?
Trust & Will publishes its Will Plan from $199, its Trust Plan from $499, Attorney Support for a flat $299 and a membership with AI answers and a digital vault at $49 a year, with an attorney led plan priced individually. LegalZoom publishes its prices too, with a 60 day refund window and installments on purchases of $200 or more, and its Doc Assist AI summarizer is free. Both charge flat prices rather than an attorney's hourly fees. From the AI Legal Index, based on each vendor's own published materials as of September 25, 2026. No vendor pays for placement.
Does Trust & Will use my estate plan to train AI?
Not in external models. Trust & Will's Terms of Service state that estate plan and account content is not used to train external AI models. The same terms reserve the right to use content generated through its AI features to provide, maintain, develop and improve its services. LegalZoom states that Doc Assist uploads may train its own proprietary models but not third party tools. From the AI Legal Index, based on each vendor's own published materials as of September 25, 2026. No vendor pays for placement.
Can I get an attorney through LegalZoom or Trust & Will?
Yes, as an add on in both cases, and both state that the platform itself is not a law firm and gives no legal advice. Trust & Will offers Attorney Support, a flat fee session with a licensed attorney in your state, names the states where it is unavailable, and offers an attorney led plan. LegalZoom offers attorney plans through independent attorneys and, where authorized, its subsidiary law firm LZ Legal Services, LLC. From the AI Legal Index, based on each vendor's own published materials as of September 25, 2026. No vendor pays for placement.
Neither vendor paid for inclusion, placement or a grade, and neither reviewed this page before it published. Everything on it comes from public material on the dates shown. How the index grades.
Two points matter. The training positions look alike and are not identical. LegalZoom states that Doc Assist uploads may train its own proprietary models and will not train third party tools. Trust & Will bars training external models on estate plan content and reserves the right to use content generated through its AI features to improve its services, without saying whether that includes its own models. Trust & Will's privacy policy has a retention section, so a retention period may be stated there. Neither vendor reviewed this page.
