Sorry to hear you had a rough time at it. My original point still stands though. Transfer of code is fine, but if the contract stipulate that IP rights are transferred upon final payment then you have the copyright stick to wield in your fight for payment as they don't actually have a valid license for the software. Obviously I am not a lawyer and you should pay one to draft a generic contract you can use for contract work.
