38 U.S. Code § 5311 - Prohibition of certain benefit payments
There shall be no payment of dependency and indemnity compensation, death compensation, or death pension which, because of a widow’s relationship with another man before enactment of Public Law 87–674, would not have been payable by the Veterans’ Administration under the standard for determining remarriage applied by that agency before said enactment.
Public Law 87–674, referred to in text, is Pub.
