Claude for Lawyers: Keep Client Context Across Every Conversation

Published June 2026 · 7 min read

If you use Claude for legal work — drafting clauses, structuring arguments, researching statutes — you've hit the same wall every time: you open a new conversation and Claude has no idea who your client is, what the dispute is about, or what position you've already taken in correspondence.

You re-brief. You paste context. You explain the same background again.

That's not a problem with Claude. That's a problem with how information is stored between sessions. Stash fixes it.

What lawyers lose in every new session

Claude's context window is large, but it doesn't persist. Every session starts from zero. The things that don't make it back in are usually the things that matter most:

None of that lives in a document. All of it has to be in your head — or re-pasted every time.

What Stash stores for legal work

Stash is a lightweight MCP-connected record store. You add structured records — not documents, not PDFs, not sensitive case files — just the working context Claude needs to assist you usefully.

Category What you store Why it helps
Matter overview Parties, dispute summary, key dates, current stage Claude can draft accurately without a full re-brief
Client context Risk appetite, communication preferences, key concerns, decision-maker Advice is calibrated to the client, not generic
Position taken Arguments made, what's been conceded, open disputes Drafting is consistent with your existing position
Counterparty notes Opposing solicitor's style, their usual tactics, previous dealings Correspondence strategy matches reality
Open issues Unresolved points, things to raise at next call, pending requests Nothing falls through the cracks

Important note on confidentiality: Stash stores your working notes — the kind of thing you'd put in a matter file memo — not the actual documents, transcripts, or privileged communications. The distinction matters for professional responsibility. Don't store what you wouldn't put in a shared note.

A realistic example

Say you're acting for a landlord in a commercial lease dispute. The tenant has stopped paying rent and is arguing the premises were unfit. You've exchanged correspondence, there's been a without-prejudice meeting, and mediation is scheduled in three weeks.

You'd add something like:

Record in Stash Matter: Commercial lease dispute — [Landlord] v [Tenant]
Stage: Pre-mediation. Mediation 2026-07-01 with [Mediator Name].
Tenant's position: Alleges fitness issues (HVAC, roof leak) — disputed. No formal inspection report provided.
Our position: Rent arrears confirmed. Without-prejudice meeting held 2026-05-20 — no settlement. Full arrears demanded.
Open issues: Tenant to provide inspection report by 2026-06-15 (chased twice, not yet received). Consider without-prejudice offer closer to mediation date.

Now when you open a new Claude session and call context(), Claude gets that summary back. You can immediately ask:

You Draft a letter to the tenant's solicitor chasing the inspection report. Firm but professional — we've already chased twice.
Claude [Drafts a letter referencing the two previous chasers, the mediation date, and the deadline, without you having to explain any of it]

That's the difference. One call to context() and Claude is working from your reality, not a blank slate.

Multi-matter lawyers hit the free cap fast

If you're running 8–12 active matters and you use Claude for drafting, research, and correspondence prep — across all of them — you'll hit the 50 free queries per month well within your first month.

At that point, the question isn't whether Stash is useful. It's whether £8/month is worth the time you save not re-briefing Claude at the start of every session.

The maths: if Stash saves 5 minutes per session across 10 sessions a month, that's 50 minutes. At any professional billing rate, that's not a close call.

What Stash doesn't do

Stash is not:

Stash is the layer between Claude and the working context you carry in your head. It makes Claude useful for your specific matters — not just for generic legal questions.

Getting started

Add Stash to Claude in two steps:

  1. Sign in at stashlite.com → get your connector URL

Free tier: 2,500 records / 50 queries per month. Pro (£8/mo): 25,000 records / 500 queries. No contract. Cancel any time.

How it fits your workflow

Most lawyers use Stash the way they'd use a matter file note — brief, factual, updated as things change. You don't need to write an essay. A few lines of structured context per matter is enough for Claude to become genuinely useful rather than generically helpful.

Start with your three most active matters. Add a record per matter. Try it for a week. If it saves time, upgrade. If not, the free tier costs nothing.
