IF I WRITE "PAID IN FULL" ON A CHECK AND THE OTHER PARTY CASHES THE CHECK, DO I OWE THEM ANYMORE MONEY?

If you have a credible dispute over payment according to an agreement or contract, and you send a check for less than the amount the creditor claims you owe, that check should be accompanied by a letter clearly stating that the check is being sent in full satisfaction of the claim, and that by cashing the check, the other party acknowledges they are accepting the settlement amount.  There are two exceptions. They apply to situations where a company cashes your check without realizing they are doing so in settlement of the claim. If the organization to whom you owe money has previously sent you a letter specifying that any such settlement checks are to be sent to a special designated address which they provide, then they have a defense against inadvertently cashing your check. The other exception is if the receiving party returns your check within 90 days. In the case of either exception, if you can prove they knew your check was a settlement offer before they cashed it, their defense fails. Did writing "Paid In Full" on your check settle your debt? You should meet with an attorney and discuss the issue in person. The advice offered here is general in nature and should not be relied upon as legal advice.
