As part of the probate process, creditors are to be notified of a death to start handling the estate. Creditors must file a claim for the amounts due within a fixed period of time to either the personal representative or, in some states, with the court. If the claim is accepted by the executor, the bill is paid out of the estate. If the claim is rejected, creditors must sue for payment. If there are insufficient funds to pay debts, states have statutes establishing who gets paid first. Executors most likely will start selling property to pay off approved creditor claims.
