Just to back Ethel up:
Nobody can make a claim against the estate in respect of a funeral, other than the person (or public body, such as the local council) arranging the funeral. Even then, the 'expenses' claimed should only cover essentials such as, for example, travelling from their home to meet the vicar/priest/etc who will be conducting the funeral, or the costs of contacting all those who might wish to attend. It would be questionable as to whether the person arranging the funeral was entitled to charge for their own travel (and/or accommodation) to actually attend the funeral. Certainly nobody else can claim unless, of course, the testator made provision in their will for such payments to be made.
