Back Up Contract Addendum FAQ

What is a Back Up Contract Addendum?

A Back Up Contract Addendum is a supplementary agreement attached to a real estate purchase contract that positions a buyer’s offer as a “back up” in case the primary contract falls through. It establishes the terms under which the secondary buyer’s contract becomes active, protecting both the seller and the back up buyer.

Why is a Back Up Contract Addendum important?

It provides clarity and reduces uncertainty during real estate transactions. If the first buyer fails to close due to financing, inspection issues, or other contingencies, the back up contract immediately comes into effect without requiring renegotiation. This saves time for sellers and ensures serious buyers remain in line for the property.

When should you use a Back Up Contract Addendum?

It should be used when multiple offers exist and the seller wants a safety net in case the primary contract fails. Buyers who are strongly interested in a property but not selected as the first choice can agree to such an addendum, giving them a clear second position.

What should a Back Up Contract Addendum include?

It should state the property details, seller and buyer information, original purchase agreement reference, the priority of contracts, conditions under which the addendum becomes effective, deadlines for notification, and any special terms agreed by the parties.
