38 CFR § 3.106 - Renouncement.
(a) Any person entitled to pension, compensation, or dependency and indemnity compensation under any of the laws administered by the Department of Veterans Affairs may renounce his or her right to that benefit but may not renounce less than all of the component items which together comprise the total amount of the benefit to which the person is entitled nor any fixed monetary amounts less than the full amount of entitlement. The renouncement will be in writing over the person's signature. Upon receipt of such renouncement in the Department of Veterans Affairs, payment of such benefits and the right thereto will be terminated, and such person will be denied any and all rights thereto from such filing.
(b) The renouncement will not preclude the person from filing a new application for pension, compensation, or dependency and indemnity compensation at any future date. Such new application will be treated as an original application, and no payments will be made thereon for any period before the date such new application is received in the Department of Veterans Affairs.
(c) Notwithstanding the provisions of paragraph (b) of this section, if a new application for pension or parents' dependency and indemnity compensation is filed within one year after the date that the Department of Veterans Affairs receives a renouncement of that benefit, such application shall not be treated as an original application and benefits will be payable as if the renouncement had not occurred.
(d) The renouncement of dependency and indemnity compensation by one beneficiary will not serve to increase the rate payable to any other beneficiary in the same class.
(e) The renouncement of dependency and indemnity compensation by a surviving spouse will not serve to vest title to this benefit in children under the age of 18 years or to increase the rate payable to a child or children over the age of 18 years.
