I suggest you just sit around and wait for the SSA to send you a letter asking for the funds to be repaid. It's a letter stating that the plan miscalculated your benefits, they should have paid you less.Some clients may receive what is called a Notice of Overpayment. This is a letter that states that the Social Security Administration (SSA) overpaid you. If you need more information than is available online, fill out the above form. You can either mail it or bring it to the Court. Use EFILETEXAS to file new cases and add additional documents to existing small claims, eviction or debt claim cases.
