The lender didn't sign the iou. Can I sign it privately in the future?
cannot

If the content of the IOU is changed by itself, and the original creditor-debtor relationship is affected, or the original conditions are changed at the time of conclusion, it is invalid.

However, it is valid if both parties agree.

For example, the added content is signed and sealed by both parties.

The contract is a fair and voluntary performance of both parties. If only one party expresses it, its validity is to be determined.
