Usually banks will pay funeral expenses out of a deceased person's account. But you must do things officially and properly, or the banks will not cooperate. After all, if you could just tell a bank to hand over someone else's money, anyone could come along and claim to be the son of a dead person and help themselves to someones money if there were no safeguards. Ask CAB, ask the banks concerned. get lots of officially-issued copies of the death certiificate - photocopies won't do.
