Binding Once Signed — With Narrow Exceptions
Once both parties have signed, a sale and purchase agreement is binding. You can't cancel simply because you've changed your mind, found a better property, or had a change of circumstances that isn't covered by a specific clause. Cancellation is only available through the specific conditions written into the agreement — and only if you use them properly and in good faith.
This is why the conditions clauses matter so much: they're not just formalities, they're the only structured exit routes a buyer generally has once they've signed.

Cancellation typically needs to be given in writing, following the notice requirements in the agreement.
