31 U.S.C. § 776 - U.S. Code - Unannotated Title 31. Money and Finance § 776. Payment of survivor benefits

(b)(1) A surviving spouse's annuity ends when the spouse remarries before age 55 or dies.

(2) A dependent child's annuity ends when the child becomes 18 years of age (unless the child is then a student as described in section 771(1)(C) of this title), marries, or dies, whichever is earliest. However, if a child is not self-supporting because of a physical or mental disability, an annuity ends when the child recovers, marries, or dies.

(3) If a surviving spouse dies and a dependent child survives, the child's annuity is recomputed under section 774(c)(3) of this title.

(4) When a dependent child's annuity ends, the annuity of another dependent child is recomputed as if the child whose annuity has ended did not survive a Comptroller General or retired Comptroller General.

(1) for a reason except death, shall be paid to the survivor; and

(2) when a survivor dies, shall be paid in the following order of precedence:

(d)(1) A payment under subsection (c)(2)(B) of this section or section 775(d) of this title is a bar to recovery by another individual.

(2) A benefit under this section and sections 773-775 of this title is not assignable or subject to legal process.
