I did some work for this company and he refuses to pay me I told him that I was going to put a lien on his property he went and got a cashier's check but he want me to bring him a lien waiver release form what do I
If it’s a final payment, you use an Unconditional Release of Lien Form. He’s entitled to that in return for a cashier’s check.
If he is about to pay you with a cashier's check and you in fact thereby get paid, obviously at that point you have no basis for the lien. So do it.
