Partner with INHERIT
We built INHERIT for ourselves, saw the wider value, and open-sourced it because interoperability only works when everyone can use it.
Why we open-sourced INHERIT
Testate Technologies builds software for estate planning — MyFamilyInherits, LegacyLists, WillsInFaith, and WillScan.ai. We needed a standard format for estate data, so we built one. Then we realised: a data format only works if everyone can use it. So we open-sourced it.
INHERIT is free to use, free to implement, and free to build upon. Apache 2.0, irrevocable.

How you can partner with us
INHERIT serves different communities in different ways. Choose the partnership type that fits your organisation — or reach out and we'll figure it out together.
Succession Law Partners
A probate solicitor and an Islamic scholar are both succession law experts, just in different traditions. We need help with intestacy distribution, forced heirship, will formalities, court processes, and religious succession rules — across all 21 jurisdictions INHERIT supports. You contribute legal knowledge; we handle the schema engineering. No technical skills needed.
See succession coverage by jurisdiction →Tax Treatment Partners
Tax advisers, accountants, wealth planners, and cross-border tax specialists — most of our extensions have outline-level tax coverage. We need help with inheritance tax thresholds, reliefs, exemptions, and double taxation treaties. Check the extensions page to see which jurisdictions need your expertise most.

Law societies, regulatory bodies, professional associations, and academic institutions can endorse the standard at whatever level of involvement suits them. Start as an observer, deepen engagement over time.
