Why bother tracking at all?
When you buy a property with someone, you both know roughly who put in what at the start. Six months in, you probably still remember. Three years in, after a kitchen renovation, two overpayments, and a bathroom refit, the picture gets blurry. Ten years in, nobody remembers anything and your solicitor has nothing to work with if you ever need to untangle ownership.
A Declaration of Trust sets the rules. A contribution record proves you followed them. Without the record, the trust document is just a set of intentions with no evidence behind it.
What solicitors actually want to see
If you ever need to rely on your Declaration of Trust (a separation, a dispute, or simply selling and dividing the proceeds), your solicitor will ask for evidence of contributions. They want:
- Dates. When each payment was made, not approximately, but specifically.
- Amounts. Exact figures in pounds and pence, not rough estimates.
- Categories. Was it a mortgage payment, an overpayment, a deposit top-up, or a home improvement?
- Attribution. Which person made the payment.
- Continuity. A complete record from purchase to present, not a handful of entries from the months you remembered to write things down.
Bank statements can fill some of these gaps, but they show outgoings, not purpose. A direct debit to your mortgage lender is clear enough. A bank transfer to your partner who then paid the builder is not.
Why a spreadsheet falls short
Most couples start with a spreadsheet. It works for a while, then one of you forgets to update it. Or you both update it and end up with two versions. Or one of you edits a row and the other does not notice. Spreadsheets have no audit trail, no access control, and no way to prove that the data has not been tampered with after the fact.
The whole point of tracking contributions is to create a record that both of you trust. If either of you can silently edit the other's entries, the record means nothing.
What a good system looks like
A contribution tracker that a solicitor would take seriously needs a few things a spreadsheet cannot provide:
- Each person can only edit or delete their own entries. Your co-owner's data is theirs.
- Every edit and deletion is logged in an append-only audit trail that neither of you can clear.
- Either of you can flag an entry you disagree with. The flag is permanent and visible to both.
- The record can be exported as a dated PDF snapshot at any time, even after you stop paying for the service.
That is the model TrustBadger follows. Not because we think relationships will go wrong, but because a fair record is easier to keep when the tools enforce fairness by design.
TrustBadger keeps a timestamped, solicitor-ready record of every contribution you and your co-owner make to your shared home. 14-day free trial, no card needed. Start your trial.
