Why proof matters more than memory
When two people buy a home together and things are going well, nobody keeps receipts. You both just pay for things. The problem comes later, if you split up, sell, or fall out: suddenly the question of who paid what becomes worth tens of thousands of pounds, and "I'm sure I put in more" is not enough.
In England and Wales, if you cannot agree how to divide a jointly owned home, a court decides on the basis of evidence. Goodwill and a good memory carry no weight. Documents do. This guide explains what actually counts as proof, and how to keep it without it taking over your life.
What the law is actually looking for
Where you are both named on the title as joint legal owners, the starting point is that you own the home in equal shares. That presumption can be displaced, but only by evidence that you intended something different, or that your contributions point to a different split. Where only one of you is on the title, the other has to prove they have a share at all.
In both situations the court is trying to establish two things: what each of you contributed, and what you intended. Solid evidence answers both. The single best piece of evidence is a signed Declaration of Trust recording your shares, which is normally decisive short of fraud or mistake. Failing that, you are relying on a paper trail.
What counts as strong proof
- Bank statements. Transfers showing the deposit leaving your account and reaching the solicitor or the seller.
- The conveyancing file. The completion statement from your solicitor shows exactly where the deposit and purchase funds came from.
- Mortgage statements. A record of who made each monthly payment, and any overpayments.
- Invoices and receipts for capital improvements, tied to the bank payment that settled them.
- Written agreements or messages. Emails or texts where you discussed how the money would be split count as evidence of intention.
What counts as weak proof
Cash is the enemy of a clean record. "I gave you £5,000 in cash for the kitchen" with nothing to show for it is very hard to prove and easy to dispute. The same goes for vague recollections, round numbers with no source document, and contributions reconstructed years after the event. Courts are rightly sceptical of records created once a dispute has already started.
Why a contemporaneous record wins
A contemporaneous record is one made at the time, not afterwards. It carries far more weight than a spreadsheet you build the week before a mediation, because it cannot be accused of being self-serving hindsight. Each entry sits next to the date it happened and the document that backs it up.
This is exactly why a casual spreadsheet often falls short: it has no timestamps, it is easy to edit after the fact, and only one of you can usually see it. We wrote separately about why a spreadsheet will not cut it.
How to keep a record that holds up
- Log each contribution when it happens, not in a batch later.
- Record the date, the amount, what it was for, and who paid.
- Keep the source document (statement or invoice) alongside it.
- Make sure both co-owners can see the same record.
- Do not rely on memory for anything that matters.
The bottom line
You cannot prove a contribution you did not record. The cheapest insurance against a costly dispute is a timestamped, itemised record that both of you can see, backed by the underlying documents. Start it on day one, keep it current, and you will never have to reconstruct your own financial history from memory.
