I'm a beneficiary on my uncle's life insurance and when he died I signed an assignment to a funeral home which I faxed to them. They say they need an original in order to process the insurance claim. I now want to rescind this assignment and file the life insurance claim for myself. I did not sign a contract with the funeral home, his wife made all the arrangements. I agreed at that time because they said they could not bury him without it. Am I still liable for this?
