A wills and estates practice runs on instructions: what the client wants, who gets what, who acts as executor, and what happens if a beneficiary dies first. None of that is hard law. It is hard admin. A principal in Sydney or a suburban practice in Melbourne can spend more time transcribing a two-hour instruction-taking meeting than actually applying the Succession Act to it. Claude is useful here precisely because the bottleneck is rarely legal judgment, it is the volume of notes, drafts and follow-up questions between the meeting and the signed will. The same pattern shows up in probate and estate administration matters, where the actual legal question (is this a valid claim, does this asset form part of the estate) is usually settled quickly, and the weeks disappear into paperwork instead.
Where the hours actually go
Ask any wills and estates lawyer where their week disappears and the answer is rarely drafting clauses. It is the surrounding admin: chasing clients for asset lists, reconciling verbal instructions against an old will, and writing the same explanatory letter about testamentary trusts for the fifth time this month. A typical Australian suburban practice handling 15 to 20 new estate planning matters a month loses a meaningful chunk of fee-earner time to this cycle.
Transcribing and structuring instruction-taking notes into a usable checklist for the file
Drafting the first pass of standard clauses (executor appointment, specific gifts, residue, guardianship) from those notes
Writing client-facing explanatory letters covering testamentary trusts, powers of attorney, and enduring guardianship in plain English
Cross-checking a new will against a prior version to flag what has actually changed
Preparing probate and letters of administration affidavits from raw asset and liability schedules
What Claude actually does with client instructions
The workable pattern is narrow and specific: a solicitor or paralegal feeds Claude the instruction-taking notes (typed or transcribed from a recording, with consent) along with the firm's clause library and precedent set. Claude produces a structured instruction summary, a first-pass draft using the firm's own precedents, and a list of gaps, missing asset details, unclear beneficiary names, an executor who hasn't been asked whether they will accept.
That first draft still goes to a solicitor for review before it goes anywhere near a client. The value is not that Claude drafts a will unsupervised, it is that the solicitor is reviewing and refining a 70 percent draft instead of starting from a blank page or a two-year-old template. For estate administration files, the same pattern applies to summarising bank statements, super fund correspondence, and the deceased's asset register into a schedule the executor can actually use.
Firms that get the most out of this start with the highest-volume, lowest-complexity matter type first, usually simple mirror wills for couples with no blended family or trust structure, before extending the same workflow to enduring power of attorney documents and then to estate administration files. That sequencing matters more than the tool itself: a firm that tries to automate a contested estate dispute in week one will conclude the whole exercise doesn't work, when the real lesson is to start with the routine 60 percent of the file load.
The guardrails that matter in succession law
Wills and estates work carries risks that a generic AI drafting tool will not understand unless the firm builds them in. Testamentary capacity, undue influence and the formal execution requirements under each state's Succession Act are not things you delegate to a model. Claude should never be the one assessing capacity, and it should never be given identifying client information beyond what the matter requires; the Privacy Act 1988 and the Australian Privacy Principles still apply in full to how client instructions are stored and processed, whether a human or a tool is doing the drafting.
A solicitor signs off on every draft before it reaches a client; nothing goes out over the firm's letterhead unreviewed
Capacity and undue influence assessments stay entirely with the solicitor, based on direct client contact
Client data is handled under the same Privacy Act and confidentiality obligations that apply to any file note or dictation
Execution formalities (witnessing, signing pages, superseding clauses) are checked against the relevant state Act, not assumed from a generic template
What this is worth in hours and dollars
For a two-partner Australian practice doing simple and mid-complexity wills at a blended rate around $350 an hour, cutting two hours of drafting and admin time off each matter is worth roughly $700 in recovered fee-earner capacity per file. Across 180 estate planning matters a year, that is in the order of $120,000 in time that can go toward client-facing work, more matters, or actually leaving the office by 6pm. On the administration side, a moderately complex deceased estate with scattered assets can take 15 to 25 hours to reconcile manually; a Claude-assisted first pass at the asset schedule and affidavit drafting has cut that by roughly a third in practices we have worked with, which on a $45,000 estate administration fee base translates to real margin, not just a time saving on paper.
None of this replaces the judgment a wills and estates solicitor brings to a family with a complicated blended structure or a contested estate. It changes how much of the week is spent on judgment versus on typing.
