Agentic UK grant of probate application preparation service for executors of straightforward estates (no IHT liability, single jurisdiction, under £500k gross) who need to apply to HMCTS for a Grant of Probate or Letters of Administration. Replaces the high-street solicitor who charges £1,500–£4,000 (or 1–2% of estate value) to complete the PA1P/PA1A forms, produce the IHT205/IHT400 schedules, and submit the online probate application — a process HMCTS has moved entirely online but which still baffles most grieving families.
Why now
No live signal batch today; grounded in HMCTS's confirmed digital probate service (apply-for-probate.service.gov.uk) which has processed 100%+ of applications online since 2022, and the Legal Services Board's 2024 report on unmet legal need in probate — both structural signals that the service is ripe for agentic replacement.
Commercial value
~250,000 probate applications filed in England and Wales annually; ~60% are straightforward estates handled by solicitors at £1,500–£4,000 each. An agentic service at £499–£799 flat fee captures an obvious saving. Even 0.5% of the market = 750 customers/yr at £650 avg = £490k ARR. Executors are highly motivated (estate distribution blocked until probate granted) and have a clear budget (solicitor fee already expected).
Go-to-market
Target executors searching 'how to apply for probate' on Google (high-intent, desperate). Partner with will-writing services (Farewill, Wills Online) for referral at point of death notification. List on Trustpilot and Which? Trusted Traders. Charge £599 flat fee. First 10 customers via Google Ads on 'probate application help' at £20–£40 CPC — probate search volume is high and commercial intent is clear.
2-week MVP
Single feature: executor completes a structured intake form (deceased details, assets, liabilities, beneficiaries); LLM populates the PA1P form fields and produces an IHT205 schedule draft as a PDF, with a step-by-step HMCTS submission checklist. A human reviewer (the founder, 30 mins/case) checks before delivery. Cut: automated HMCTS portal submission, IHT400 for taxable estates, multi-jurisdiction assets. Day-1 outcome: executor receives a completed, ready-to-submit PA1P + IHT205 pack they'd otherwise pay a solicitor £1,500–£4,000 to produce.
Agent score
0.62 — Commercial score is high — named solicitor budget (£1,500–£4,000), 250k annual applications, strong executor urgency, and a clear price anchor; speed is slightly lower because the human-in-the-loop review step requires founder time per case and Google Ads requires a small budget, but the MVP form-to-PDF is still shippable in ~2 weeks; defensibility is moderate — brand trust and Trustpilot reviews compound over time, but the core workflow is replicable without proprietary data.
