38 C.F.R. § 13.260
(a) Distribution of funds. Benefits deposited by VA in the personal funds of patients account for a veteran who was rated by VA as being unable to manage his or her VA benefits and who died leaving an account balance are payable to an eligible person. For purposes of this section, eligible person means an individual living at the time the account balance is distributed in the following order of preference:
(b) Application. A person who seeks distribution of a deceased veteran's funds from the personal funds of patients account under paragraph (a) of this section must file an application with VA not later than 5 years after the veteran's death. If any person who seeks such distribution is under a legal disability that prevents him or her from filing an application at the time of the veteran's death, the 5-year period will run from the date of termination or removal of the legal disability.
