Family Law AI and the Best AI for Family Law Firms by Job and Price

What does family law AI actually do?

Family law AI is not one product. It is four tools aimed at the four places a divorce or custody matter eats hours. The first is the money: financial affidavits, child support guidelines, spousal support, property division and the what-if scenarios a client asks for at every settlement conference. The second is paper: petitions, parenting plans, marital settlement agreements and discovery requests built from the same facts typed into intake. The third is the record: depositions, hearing transcripts and the stack of bank statements and tax returns that come back in discovery. The fourth is the law: what courts in your state have actually done with a relocation request, a commingled inheritance or a cohabitation clause.

Most of the "best AI for family law" lists mix all four together and rank tools that do different jobs against each other. That is how a firm ends up paying for a practice management suite when it needed a support calculator, or buying a research platform on a three year term to answer two relocation questions a quarter. The useful question is which of the four jobs costs your team the most hours, and what the cheapest tool that does that job well costs.

How much does family law AI cost?

Less than most firms expect, if you buy by job. Family Law Software lists three cloud plans: Basic at 39.95 dollars a month for financial affidavits and support calculations, Individual at 69.95 dollars for a single user who also needs property division, alimony buyout and arrears tools, and Firm at 79.95 dollars for multi-user access, each with a 99 dollar initial charge and a two month money-back guarantee. Gavel starts at 83 dollars a month on its Lite plan and reaches 290 dollars on Pro, which adds organization seats, a legal template library and payment collection, with a seven day trial and no card required.

CaseMark charges 25 dollars per legal summary and 5 dollars an hour for transcription, with no monthly fee, so a firm that summarizes three depositions a month spends about 75 dollars. Clio Manage starts at 49 dollars per user, and Clio Work launched in October 2025 as a 199 dollar per user add-on for Clio Manage subscribers. The expensive line is usually research: Westlaw Edge for one state starts at 107.25 dollars a month on a three year term, and Lexis+ Essential at 114 dollars, both on multi-year commitments.

Which family law AI tools do case law research?

Few of them. Family Law Software, Gavel and CaseMark do not search case law at all, and that is by design. Clio Work includes research through vLex, the legal database Clio acquired in 2025, but it is sold per user on top of Clio Manage. Westlaw and Lexis+ do research thoroughly, with KeyCite and Shepard's, but entry plans start above 100 dollars a month and the online prices assume a one to three year term.

Family law questions are state questions, which makes research both narrower and more important than it looks. Nine states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin) are community property states and the rest divide property equitably, so whether a premarital asset became marital through commingling turns on your own appellate courts. Relocation, grandparent visitation and the weight given to a child's preference vary the same way. A plain-English research tool lets you ask the question as you would say it to a colleague and read the controlling decisions.

Where CaseSearch fits in a family law practice

CaseSearch does the research job and nothing else. Ask in plain English, for example whether Florida courts have allowed a parent to relocate more than 50 miles over the other parent's objection where the move was for a job offer, and you get the on-point decisions with citations, the holding in plain language and a signal showing whether each one is still good law. That is the research behind a relocation petition, a response to a modification motion or a memo on whether an inheritance kept its separate character.

It does not calculate support, draft parenting plans or summarize transcripts, and it is not legal advice. It costs 49 dollars a month, or 24 a month billed yearly, with no sales call and no multi-year term, and one real question at the top of this page runs without an account. Paired with a support calculator and a document automation plan, it gives a small family law firm the whole stack for less than one entry-level research platform seat.
