Hello. Wonder if someone can point me in the right direction. I'm in the process of negotiating a payment for breaking a lease. I'm out of that state now. I will send them a check when we agree on the final amount however at the same time I want them to sign a form stating that the charges are paid in full and no further claims will be made against me. I don't know how to do this. If I send them the check (which will be lower than they said I needed to pay originally), what will keep them from cashing the check and still claim I owe more money? It seems when you get checks from insurance companies, your endorsement of the check means you sign off on that claim. How would it work in this case? Thanks for any help!
