Ledger & Lease
Private proof records for property compliance — converting landlord and agent evidence into dated proof records with third-party verification links.
The messy workflow
When a tenancy dispute happens, the question is always the same: what was sent, when, and for which property? Landlords and agents do send the right notices and documents — but the proof is scattered across email threads, screenshots and PDFs, with no reliable record of timing or context.
Ledger & Lease preserves that proof at the moment it's created, so it holds up later — without asking users to become compliance experts.

System flow
The AI layer — and its limits
AI interprets the evidence, drafts the record and guides the user through what's missing. It does not give legal advice or assert that a notice is legally valid — it preserves and organises proof, and is explicit about being a record-keeping tool, not a legal authority.
Guardrails
- User reviews and confirms each record before it's saved
- Records are dated and tied to a specific tenancy
- Verification links let a third party confirm a record independently
- Privacy-first: evidence folders are private by default
- Clear framing of limits — proof, not legal judgement

What I learned
Trust in a compliance product comes from restraint. The temptation is to claim the tool makes you compliant; the honest — and more defensible — position is that it preserves verifiable proof and is clear about its limits. Designing the UX to never over-promise was the most important product decision.
