Addendum
A written amendment adding to or changing the terms of an existing contract.
In plain English
An addendum modifies or adds to the original purchase agreement (commonly used for repair agreements, financing changes, or closing date extensions) and must be signed by both parties to take effect.
Why it matters
Any change to your original agreement should go through a proper addendum, not just a verbal or informal understanding.
