Selling estate planning firm data for AI training: what it's worth and who buys it
micro1 lists templates, playbooks and knowledge bases among the data it buys, and an estate planning practice drafts almost every document from a template set built over years.1
An estate planning practice is built on a document system. The firm keeps a set of trust, will, power of attorney and health care directive templates, a design questionnaire that captures each family's situation, and a list of rules for when a plan needs a special provision: a blended family, a child with special needs, a business interest, property in another state. Probate and trust administration add a second workflow: inventories, creditor notices, accountings, distributions.
The firm's reasoning lives in how it adapts the templates. That is the record buyers describe: micro1 lists templates, playbooks, SOPs and task histories, and names legal and compliance. Lawyers are a GDPval occupation, and paralegals score 100 out of 100 on O*NET's email scale.
Every client file, though, holds a family's finances, health wishes and relationships. So the useful package starts with what the practice wrote for itself: the template library and its drafting notes, the design questionnaire, the signing-ceremony checklist, the funding instruction letters, the probate task list. Raise anything that describes a real family with the licensing company before it leaves the office.
Worth
What a practice's data may be worth
Pre-set for a typical practice: 20 staff and 15 years of records. No buyer publishes pricing by industry, so industry does not move the band. Our estimate, not a buyer quote.
Buyers
Which buyers want this data
Each reason is the buyer's own published statement about the tools, data or industries it takes, matched to how estate planning and probate practices work.

Buyer demand
How buyers' own tools rate estate planning and probate practices
No buyer publishes a price list by industry. These are settings inside buyers' and brokers' own estimators and intake forms, read from their public pages on 2026-10-14. They show how each company sorts industries, not what any practice was paid. The category shown is the one a practice would most likely pick; that match is ours.
| Company | Its category | How it rates the industry |
|---|---|---|
| Troveo | Legal | Tier 2 of 4: "Your industry carries above-average buyer demand." Price factor 1.15 in its estimator.23 |
| Polyshares | Legal | Marked premium in its intake list24 |
| VMS | Law | Higher weight in its estimator (factor 1.30)25 |
| Ventra | Legal, healthcare, financial services or accounting | Says it cannot take these industries right now26 |

What buyers value
What in a practice's records buyers value
The column on the right is not legal advice: it lists what to raise with the buyer before anything is exported.
| Data | Where it lives | Why a buyer values it | Raise with the buyer |
|---|---|---|---|
| Template library with drafting notes | WealthCounsel, Lawmatics or Word templates | Trust, will and directive templates plus the notes on which clause to use when, the core of how the practice drafts. | Nothing specific |
| Design questionnaire and intake rules | Web forms or the CRM | The questions that decide a plan's structure, and the rules that flag special cases. | Completed questionnaires, which describe real families and assets. |
| Signing-ceremony checklist | Shared drive | Witness, notary and execution steps that vary by document type and state. | Nothing specific |
| Funding instruction letters | Document assembly and email | How the firm tells clients to retitle accounts and property into a trust, written for non-lawyers. | Account names and property details in sent letters. |
| Probate and trust administration task lists | Clio, practice management or spreadsheets | Inventories, notices, accountings and distributions as a step-by-step workflow with deadlines. | Estate assets, heirs and creditor details in each matter. |
| Client education and seminar materials | Website, newsletters, slide decks | Plain-language explanations of planning concepts that the firm wrote to win clients. | Nothing specific |
A week of records
A week of data at a practice
- Monday: six design questionnaires come in; the paralegal flags two for blended-family provisions.
- Tuesday: the attorney adds a drafting note to the trust template after a client asks about a vacation property in another state.
- Wednesday: three signing ceremonies, each run from the checklist with two witnesses and a notary.
- Thursday: funding letters go out for last week's signings, with the standard retitling instructions.
- Friday: a probate inventory is filed and the administration task list moves to creditor notices.

- PII removed "when relevant"12

Selling or closing
Selling or closing your practice? License its data first
Estate planning is a practice where the founding attorney's retirement often decides the firm's future, and succession is usually the moment the archive gets looked at. If a sale or wind-down is ahead, ask each licensing company whether the template library, drafting notes and administration workflows can be licensed separately from client files. Pewter says it takes firms that are winding down or closed while the records still exist.2
FAQ
Estate planning and probate firms: questions, answered
No buyer prices estate practices on their own. Published ranges mostly run $100K to $2M, as the buyers' own claims: Nyne says its typical deal is $100K or more, Jottings quotes $100K-$250K for specialized histories, and monsterdata.ai $50K-$1M for a one-time sale. A package of templates and workflows should be priced as that from the first call.21,44,45
They are written by the firm for the public and are close to the internal docs and knowledge bases micro1 lists. They rarely name clients, so they are usually the easiest material to describe on a first call.1
