Loans and transfers in sugar relationships: proving what happened
Money in a sugar relationship rarely comes with an IOU. When it ends, one side calls the payments loans and the other calls them gifts. A single bank record cannot settle that.

A transfer proves movement, not intention
Money in a sugar or extramarital relationship often moves as red packets, rent, shopping or a monthly allowance. Few people write an IOU. After it ends, the payer calls the money a loan and the recipient calls it a gift.
A payment record proves only that an amount left one account and entered another at a particular time. It does not prove that the parties agreed on a loan, interest or a repayment date.
Articles 667 and 679 of the Civil Code require both a lending agreement and actual delivery for a loan between natural persons. This is general information, not legal advice; consult a lawyer or the 12348 public legal service. The Code is in the National Laws and Regulations Database.
Build a chain, not a single screenshot
Courts look for evidence that corroborates itself: delivery, intent, acknowledgement, part-performance and identity. Two or three connected links are stronger than one screenshot.
| Link | What it shows | Typical material |
|---|---|---|
| Delivery | Money reached the borrower | Bank statement, WeChat or Alipay transfer certificate |
| Intent | The parties spoke of borrowing | Chat logs, voice messages, a written note |
| Acknowledgement | A duty to repay was accepted | Repayment plan, 'I will pay next month', recorded call |
| Part-performance | Something was actually repaid | Incoming transfers, receipt, confirming message |
| Identity | Chat account and receiving account match | Real-name data, phone number, witness |

The decisive link: did anyone say 'borrow'?
Without an IOU, chat logs often decide the case. 'I will lend you 20,000 for rent, repay me after payday' differs from 'take it, you do not need to return it'.
A transfer with no explanation is the weakest position: the recipient can call it a gift, allowance or compensation, all plausible in an intimate relationship.
Save the whole conversation with names, handles and timestamps. A cropped line can be attacked as incomplete.
Export payment records properly
Request a transfer certificate or transaction statement from WeChat Pay or Alipay rather than relying on screenshots. Menu names change, so search in-app help.
Check the real names, amount, time and order number. Those details connect the person in the chat to the account that received the money.
If you only have a nickname, a court investigation order or a lawyer may be needed to obtain real-name data. Buying personal data privately can itself be unlawful.
Promises and part-payments carry weight
A written schedule, a transfer marked repayment or 'I will pay the rest next month' is stronger than 'of course I will pay'.
Part-payment helps too: if someone who denies borrowing keeps sending matching instalments, a court may infer a loan.
Keep proof of reminders. You may record a call you take part in, provided the recording is not obtained through serious illegality. If interest was not agreed, a loan between natural persons is generally interest-free.
Recordings, witnesses and electronic data
You may record your own call; planting a device, hacking an account or copying contacts can violate privacy and be excluded.
Keep recordings continuous and unedited; state the date, parties and amount at the start. A clip beginning with 'fine' proves little.
Witnesses matter if they saw cash change hands or heard repayment discussed. Evidence rules require courts to assess electronic data by how it was generated, stored and transmitted, and whether it is complete.
The three-year limitation period
Article 188 sets a three-year period from the day the creditor knew or should have known of the harm and the debtor. With no repayment date, it generally starts after a demand and a reasonable grace period; with a fixed date, the day after.
Article 195 restarts the clock when the creditor demands performance, the debtor agrees to perform, or a suit or arbitration is filed.
A demand must be provable: keep the message and reply. Limitation is a defence, but once raised it can end the claim.
When a spouse is involved
If the money lent came from joint marital property, the lender's spouse may also be a joint creditor and may claim in a divorce.
Article 1064 limits joint marital debts to those jointly signed or ratified, or incurred for ordinary family needs. A personal loan beyond that is not joint unless the lender proves it was used for shared life, a joint business or a common intention.
Money spent on an extramarital relationship is hard to call an ordinary family need, so the borrower's spouse may dispute the debt. Trace the source and ownership before claiming.
Five things not to do
- Do not backdate or forge an IOU; altered dates can lead to fines, detention or criminal liability.
- Do not threaten exposure or contact family or employers; a lawful debt pursued by threats can become extortion.
- Do not fabricate chats, screenshots or receipts.
- Do not send another transfer to 'create evidence'.
- Do not keep the only copy on a device the other person can access.
Common questions
Can I sue with only a transfer record?
You can file, but if the other side claims a gift you need material showing a loan agreement, or you may fail on the burden of proof.
Does a transfer note saying 'loan' settle the case?
No. Courts also look at the chat context, the relationship, repayment behaviour and interest terms. A unilateral note is not agreement.
What if more than three years have passed?
You can still sue, but limitation may be raised. Check for a demand, repayment promise or part-payment that interrupted the period.
