What would happen if one died before slip fall case was filed?

I'll keep it simple. Take this up with the representative of his decedent estate. Why would you want his claim to die with him?

Your question is missing some information. I assume your father hired the attorney to handle the case, so it was alright for the attorney to proceed forward, but the attorney had no ability to settle the case without either your father's signature or, since he was dead, that of the administrator of his estate. The insurance company would not settle without getting that signature. So I do not see how the attorney could settle without the approval of the person handling the estate. Upon your father's death, any claim he had for pain and suffering disappeared. There is a one year statute of limitations to sue for malpractice.

Dad?s estate is entitled to payment for any medical expenses, but not pain and suffering. Slip and fall cases are usually discounted because of questionable liability.
