Sibling 2 purchased a headstone and slab for the grave with their own money . Sibling 1 is angry because , this should have done this through the insurance policy & is threatening to sue the memorial place and sibling 2 . Sibling 1 states that permission was not given to put headstone or slab down because he is owner . . It has been over 10 years since the death . Sibling 1 never complained about the slab that was put down immediately after the death but is complaining about the headstone . Can he sue Sibling 2 or the memorial company and prevail ? Although Sibling 1 is the beneficiary , this is also Sibling 2's mother as well , what are Sibling 2's rights ?
