2. The date of borrowing must be clearly written, and it is best to be accurate to the day. The repayment date can be agreed in the IOU. If there is no agreed repayment date, the borrower can claim repayment at any time. If the repayment date is agreed, the request can only be made when the repayment date expires. If the repayment date is not returned, the lender will lose the right to win the case within three years.
3. The loan amount should be capitalized in Arabic numerals and Chinese at the same time, and the currency should be clearly written, such as "RMB 100000.00 Yuan only (RMB one hundred thousand Yuan only)" to prevent the loan holder from tampering.
4. Payment shall be made by bank transfer as far as possible, and the account number and transfer date of the other party may be indicated on the debit note. When handling the transfer, you can indicate the purpose of the loan. If the amount is small, it should be indicated on the IOU that both parties' loans are paid in cash. Either way, the borrower needs to write a receipt for the money received separately. The IOU can only prove that there is a loan contract relationship between the two parties, which is not enough to prove that the borrower has fulfilled the obligation to repay the money.
5. If the amount is large, you can ask a lawyer or a third party to witness and sign.
