Lent Money to an Ex-Partner Who Won't Pay It Back? Proving a Relationship Loan in Hong Kong

While you are dating or living together, money is rarely counted precisely: you cover the rent this month, they cover it next month; you book the flights, they pay for dinner. Then one day one of you really needs money, a larger sum is transferred, and both of you assume it will obviously be repaid — who writes a loan note for that? After the breakup, the other person says "that wasn't a loan, it was just our shared living costs," and you discover you have almost nothing to show. This article is a companion to our piece on family loans that turn into "gifts", but couples add one more layer: a long stream of transfers in both directions, which makes it hard to point to which payment was the loan. It draws on CLIC — the Community Legal Information Centre and the Hong Kong Judiciary.

Why a Loan to a Partner Is Different From a Family Loan

The difficulty with family loans is mostly that relatives feel awkward asking for a signature. With couples there is an extra problem: regular transfers are part of the relationship itself.

You may have shared savings, taken turns paying rent, covered each other's credit cards, and split flights and hotels. Against that background a transfer could be a loan, a share of costs or a treat, and the bank record alone cannot tell you which. All the other person has to say later is "that was just part of our everyday spending," and you must explain why this payment differs from dozens of others.

So the real question is not "can this be recovered in law?" but "can I separate this payment from everything around it?"

The Law Does Not Take Sides Because You Dated

The good news and the bad news.

Per CLIC, Hong Kong civil cases — including this kind of money claim — apply the "balance of probabilities" standard: whichever account is more likely to be true is the one accepted. The burden is on the party making the assertion, which means you must show the payment was a loan. The law does not presume that a transfer between partners is a gift, and it does not presume it is a loan.

The bad news is that the burden is yours. The good news, per another CLIC page, is that proof is not limited to oral testimony: documents, photographs, recordings and electronic data all count. WhatsApp and Instagram messages and bank transfer records can all be used.

Separating a Loan From Everyday Expense-Sharing

The more of these you have, the stronger your position, and they are the points an Adjudicator is most likely to look at:

• A message that frames the payment as a loan — "I'll pay you back after payday" or "I'll return it in instalments" is far stronger than a vague "thanks"
• Any part-repayment — even a small one is an acknowledgement of the debt, and it may restart the limitation clock (see below)
• The transfer's reference field — if "loan" or "repayment" was typed at the time, that is the most direct contemporaneous record; a heart or emoji helps very little
• The size of the sum against the couple's usual pattern — if everyday transfers run from a few hundred to a few thousand dollars and this one is a round figure well above that, it looks more like a discrete loan than shared costs
• What the other person said afterwards — a message after the breakup such as "I know I still owe you…" can be used

Be realistic as well: if you transferred money to each other frequently over the past year, a tribunal may expect you to explain the net position. A simple timeline that separates the disputed payment from the rest of your dealings will serve you better than lumping everything together.

Where you can, also keep the surrounding context: a screenshot of the conversation that led up to the request ("I'm short this month, could you lend me…") is often more persuasive than the transfer alone, because it shows what both of you understood at the time. Export whole conversation threads rather than a few selected lines, so nobody can say the screenshots were cherry-picked.

Electronic records like these are usable in the tribunal: in a case involving an unpaid loan to a friend, the claim was brought on FPS screenshots and WhatsApp messages. It simply shows how this kind of evidence can be used; every matter turns on its own evidence, and it is not a promise about your claim.

One Large Transfer and Nothing Else

To be blunt: if all you have is one large transfer, with no mention of repayment before or after and no repayment ever made, proving it is clearly harder than a business debt with a signed note. It becomes your word against theirs, and the Adjudicator has no objective record to lean on. Some claims in that position are simply not recoverable.

It is not entirely hopeless. Your first chasing messages after the breakup, and the other person's replies (even "I don't have the money right now" implies a debt), can help. But they are after-the-fact evidence and carry less weight than contemporaneous records. The practical answer is to start keeping records today rather than wait for a dispute.

If you do have a written note or other document, our loan note guide has a template.

The Step to Take on Every Large Transfer From Now On

The simplest habit: whenever you send a sizeable sum to a partner, immediately follow it with a message such as:

"Just sent you $XX,XXX — remember this is a loan, repay when you can."

It need not be formal, and it does not signal distrust. It costs nothing, and if a dispute ever arises it is the most direct contemporaneous evidence you could have. Also type "loan" in the transfer's reference field.

How to Raise It After a Breakup Without Hurting Your Case

Emotions run high after a breakup, but the more heated your messages, the less they help you later. The steadier approach is to write (WhatsApp or email), in a plain tone, and stick to facts:

• Identify the exact payment: give the date and amount, for example "Do you remember I transferred $XX,XXX to you on [date]?", so the other person cannot claim not to know which one you mean
• Call it a loan: use the words "loan" and "repay" rather than something vague like "you owe me"
• Give a reasonable window to reply: for example, ask for a repayment proposal within two weeks, so that either a reply or silence is on record
• Do not threaten or shame them publicly: telling mutual friends or posting online that the person owes you money can create a separate defamation or harassment problem, and usually hardens the other side

If the other person answers "I'll pay you back" or offers instalments, keep the message — it may itself be an acknowledgement of the debt. A chasing message is one step in organising your evidence; it does not guarantee that they will pay, and if there is no response at all, filing a claim is the next thing to consider.

The Six-Year Limit and Filing at the Small Claims Tribunal

Watch the clock. Per oln-law.com's summary of the Limitation Ordinance (Cap. 347), a claim founded on a simple contract, including a private loan, generally has to be brought within six years, counted from the breach (usually the day repayment fell due and was missed), not from the day you lent the money. If the debtor acknowledges the debt in a signed writing, or makes a part-payment, within that period, the time runs afresh from the acknowledgement or last payment. So a repayment or a written "I will pay you back" after the breakup may be the new starting point. See our full limitation guide.

For claims of HK$75,000 or less, the Small Claims Tribunal is an option; per the Judiciary, filing fees are tiered by claim amount, from HK$20 to HK$120. Before filing, organise transfer records, message screenshots and your timeline into an evidence bundle, and see the Small Claims Tribunal guide for the process.
