What Is an IOU
An IOU is an informal loan agreement between a lender and a borrower. It puts the debt in writing, and the person who borrows your money has a responsibility to pay it back.
An IOU is sometimes referred to as:
Debt Acknowledgement Form
I Owe You
Many times this document is used between 2 people with a previous relationship. Even though it is not considered formal, the agreement can be enforceable and used in court.
An I Owe You states the amount of money borrowed and when it needs to be paid back by the borrower.
When to Use an IOU Template
Using a simple IOU form to complete every type of agreement is not recommendable. It is a much more informal type of loan agreement and shouldn’t be used for formal transactions.
However, an IOU is the best option in certain moments, for example:
You loan money to a friend or family member
You buy an item for someone who doesn’t have enough money
You pay for an event such as a wedding and want the money back
Using an IOU or not, depends on the relationship you have with the borrower. This document is often reserved for family members, friends, and coworkers.
If you do not use an IOU, you may have trouble getting your money back. This can cause strain in your relationship with the borrower as well as a legal dispute.
