What you have written is the classic attempt by someone to pay less than what he or she is legally obligated to pay on the judgment by writing "final payment" on the check. Since there is a set amount owed you per the court's judgment, you should make a copy of the check and cross out the "final payment" and write partial payment and then cash the check.By having a copy of the check, you now know where the landlord banks for levy purposes to collect the balance that is owed you.
