1. If the company doesn't have a formatted IOU, write it like this: IOU, I am an employee of a company, and I borrowed RMB (in words and figures) from a company for something (such as advance travel expenses, advance salary, etc.). Payee: XXX. Mark the year, month and day.

2. Legal basis:

Article 668 of the Civil Code of People's Republic of China (PRC)

A loan contract shall be in written form, unless otherwise agreed between natural persons. The contents of a loan contract generally include terms such as loan type, currency, purpose, amount, interest rate, term and repayment method.

Second, what should I pay attention to when writing IOUs?

1. The IOU must be written by the borrower, not the lender, which can prevent the borrower from refusing to recognize the validity of the IOU on the grounds that the lender has written the contents without authorization;

2. IOUs should be as concise as possible. Don't use ambiguous language. For example, the language "A borrows 10,000 yuan from B" can't make it clear who borrows money from whom. In the absence of a clear direction, you should use "borrow" instead of "borrow";

Don't write the reasons for borrowing money from you, such as: Why do I borrow money from you? This has nothing to do with borrowing money itself. If I join, it may lead to a civil act of conditional lending and cause the borrower to invoke a conditional defense;

4. Attach the ID numbers of the borrower and the lender as much as possible, which will be reflected in the IOUs, so as to avoid the unnecessary process of confirming the parties to the IOUs. Because sometimes some people's daily names are different from those on their ID cards. If the borrower associates with you and writes an IOU under a pseudonym or nickname, then the signature of the IOU is seriously flawed.

Most importantly, the borrower's signature must be seen with his own eyes. If the borrower signs his name with someone else's hand, it will lead to the loss of loan proof. Therefore, don't accept written IOUs or IOUs written afterwards. You must ask the borrower to write the IOU in person. The loan itself must be a complete piece of paper, not a torn or scratched piece of paper. There is a real case in which a borrower repaid the loan several times. The borrower used the torn part of the loan as a defense, and finally the judge accepted the borrower's combination with other documents and ruled that the lender lost the case.
