For co-owners in the UK

A diligent little record
of who paid what.

If you own a home with someone you're not married to, your beneficial share shifts with every deposit, mortgage payment, and bit of DIY. TrustBadger is the honest, timestamped ledger you'll both actually keep up with - and the PDF your solicitor will accept.

How it works

Three small habits. One honest record.

  1. 01

    Tell us the basics

    Address, purchase price, deposits, who's on the mortgage. Five minutes, one sitting.

  2. 02

    Log what each of you pays

    Mortgage, renovation, fees. A tap on your phone after a direct debit clears. Both of you see it.

  3. 03

    Export the PDF when it matters

    Dated, paginated, formula-stamped, with a full audit trail. Take it to your solicitor.

Who it's for

Two people, one property, a Declaration of Trust that floats.

You're probably not married. You put in different amounts. The deed says your shares shift with what each of you pays. Right now that's a spreadsheet nobody's updated since July. We can do better than that.

  • Both co-owners log in. Both see identical screens.
  • Only you can edit your own entries. Disagree? Flag it - don't overwrite it.
  • Every change is stamped with who, when, and why.

Fair questions

Is this legal advice?

No. TrustBadger keeps a record. Your solicitor decides what it means. We say so on every screen, not just in the small print.

What if my co-owner and I disagree about an entry?

Neither of you can overwrite the other. You can flag an entry to mark it disputed - it stays visible, both sides of the conversation preserved, and shows up in the PDF.

How does the split calculation work?

One contribution-weighted formula with toggles. Deposits always count. You choose whether to include mortgage payments, overpayments, capital improvements, repairs, and bills. Turn them on or off any time from Settings. Every change is logged on the audit trail.

Can we cancel any time?

Yes. Your record stays exportable as a PDF even after cancellation - the honest thing to do, we think.
