Notice to Buyer to Perform
Also called: NBP
A formal notice a seller sends when a buyer misses a contract deadline, giving them a short time to act before the seller may cancel.
If a buyer misses a deadline — removing a contingency, delivering their deposit, or providing loan documents — a seller usually cannot just cancel. The Notice to Buyer to Perform (a California form) tells the buyer to do what the contract requires.
The notice gives the buyer a short period to perform, typically two days after it is delivered unless the contract says otherwise. If the buyer still does not act, the seller may then be able to cancel the contract in writing.
What it means for you as a seller
This is the formal step between "the buyer is late" and "I can cancel". Timing and delivery matter, so talk to your agent before sending one.
