IOUs generally consist of three parts: title, text and signature.
(1) title
The title of IOU is generally composed of language names, that is, the word "IOU" is written in large font at the top and middle of the text. Some people write the words "temporarily owed" or "now owed" in this position as the title, but the text of this title is written in the top box of the next line.
(2) Text
The subject of the IOU should write down what the person or unit owes, what it owes and how much it owes, and indicate the repayment date.
(3) Signature
Signature should be accompanied by the name of the owed unit and the personal signature of the handler, and the personal name of the owed party should be attached to the debit note issued by the individual. Meanwhile, the date of signing the debt. Units should build official seals and individuals should build private seals.

Writing of IOUs:
1. It's best to attach the ID numbers of the lender and the borrower in the debit note to avoid unnecessary disputes.
2. When the borrower signs, the lender must see his signature with his own eyes to prevent the borrower from signing with others, and finally refuse to recognize the IOU.
3. The borrower must be the borrower, not the lender, otherwise the borrower will argue that the content is not the original.
4. Try to avoid using different languages. Simple and semantically simple IOUs are the most standard IOUs. Avoid vague language like "A borrows money from B", because it is easy to tell who is the lender and who is the borrower.
The name should be written as IOU, not IOU. Their legal meanings are quite different. IOUs are valid for 20 years and IOUs for 2 years.
