Who are you?

I work in estate administration

Solicitors, probate practitioners, will writers, tax advisers. Your estates team handles the same data in different formats for every case — wills as PDFs, asset lists as spreadsheets, tax calculations in separate tools. INHERIT gives estate data one structured format that validates automatically.

I build software that handles estate data

Practice management, wealth platforms, court filing systems. Your users' estate data is trapped in your platform. INHERIT makes it portable — structured, validated, and interoperable with any other INHERIT-compatible system.

I’m evaluating this for my organisation

Law societies, regulators, professional bodies, insurers. You need to know who’s behind it, how it’s governed, and how mature the coverage is for your jurisdiction.

The same answer. Every time.

INHERIT uses a rules-based system, not artificial intelligence. The same document always produces the same validation result — no matter who runs it, when, or where. No ambiguity. No hallucinations. No surprises.

How It Works →

Jurisdiction-aware by design

Estate law varies dramatically between countries and legal traditions. INHERIT encodes these differences so your data is valid wherever it needs to be.

🇬🇧 England & Wales 🇬🇧 Scotland 🇬🇧 Northern Ireland 🇮🇪 Ireland 🇺🇸 United States 🇦🇺 Australia

21 jurisdictions across 7 legal traditions — from IHT nil-rate bands to Islamic forced heirship.

What makes INHERIT different

Purpose-built for estate planning, not retrofitted from another domain.

🩹

Healthcare interoperability

Sensitivity markers, redaction support, and data classification at the field level. Built for GDPR and beyond.
