Military pensions and the TSP in divorce: USFSPA and RBCOs

A military divorce divides retirement under a different rulebook. The QDRO that splits a private 401(k) has no power over military retired pay or the Thrift Savings Plan — each needs its own kind of order, each has its own federal statute, and the traps are different: a ten-year threshold that governs who sends the check, a “frozen benefit” rule that fixes the share at divorce-date rank, and a category of pay the Supreme Court has put entirely off the table.

A different rulebook: why the QDRO stops at the base gate

ERISA — the statute that makes QDROs work — doesn't govern federal military benefits. Congress wrote separate divorce provisions into the military retirement system and the Thrift Savings Plan, which means a settlement that says “retirement accounts will be divided by QDRO” has, for a military family, promised a tool that doesn't fit either lock. As with the non-401(k) accounts covered in our 401(k) guide, the first drafting decision is matching each benefit to the order that actually reaches it:

• Military retired pay — the defined-benefit pension — divides under a court order that satisfies the USFSPA, enforced through the Defense Finance and Accounting Service (DFAS).
• The Thrift Savings Plan — the defined-contribution account for service members and federal employees — divides under a retirement benefits court order (RBCO) served on the TSP.
• VA disability compensation — divides under nothing. Federal law keeps it out of the marital pot entirely, as covered below.

The USFSPA: what it permits and what it caps

The Uniformed Services Former Spouses' Protection Act is a permission slip, not a formula. It provides that a court “may treat disposable retired pay payable to a member … either as property solely of the member or as property of the member and his spouse in accordance with the law of the jurisdiction of such court.” State law still decides how much is marital and how it splits — typically through the same coverture-fraction logic used for civilian pensions.

Two federal limits sit on top of state law. First, only disposable retired pay divides: gross retired pay minus certain deductions, including amounts waived to receive VA disability compensation and disability retired pay computed from a disability percentage. Second, the statute caps division: the total payable under all property-division orders “may not exceed 50 percent of such disposable retired pay.” (Garnishments for alimony or child support ride on separate authority and can push total withholding higher.)

The 10/10 rule: who sends the check

No provision of the USFSPA is misread more often. The statute conditions direct payment from DFAS — not the award itself — on the marriage lasting ten years or more during which the member performed at least ten years of creditable service. Fail the test and the former spouse's share is just as valid; it simply arrives from the retiree instead of the government, with the enforcement headaches that implies. Meet the test, and the former spouse applies to DFAS with a certified copy of the order and receives their percentage of each month's disposable retired pay directly.

Settlement drafting should anticipate the difference: a share paid retiree-to-ex-spouse deserves the same protective clauses you'd put around any private stream — life-insurance security, clear tax allocation, and default remedies — because DFAS won't be standing behind it.

The frozen benefit rule: the share stops growing at divorce

For decades, states disagreed about whether an ex-spouse's percentage should apply to the pension as it stood at divorce or as it stood at retirement — the same fight that surrounds the valuation date in 401(k) orders. For military divorces, Congress settled it in the 2017 defense authorization act. For a member not yet retired when the decree becomes final, divisible pay is now computed from “the member's retired pay base and years of service on the date of the decree,” then increased by the cost-of-living adjustments that follow until and after retirement.

In practice: the ex-spouse's share is built on the rank and service the member had at divorce — a sergeant's pension, even if the member retires a sergeant major — with COLAs preserving its purchasing power. Post-divorce promotions and longevity belong to the member alone. Orders drafted for still-serving members must therefore state the retired-pay base and years of service as of the decree date; DFAS rejects orders that leave it unable to run this computation, the military cousin of the qualification failures that bounce civilian QDROs.

VA disability: off the table, even by the back door

Many retirees waive a slice of retired pay to receive VA disability compensation instead — the disability money is tax-free, so the waiver is nearly automatic. But waived amounts drop out of “disposable retired pay,” which shrinks the pool the ex-spouse's percentage applies to. The Supreme Court closed the obvious workaround in Howell v. Howell, 581 U.S. 214 (2017): “a state court may not order a veteran to indemnify a divorced spouse for the loss … caused by the veteran's waiver of retired pay to receive service-related disability benefits,” building on Mansell v. Mansell, 490 U.S. 581 (1989), which held federal law “completely pre-empts the States from treating waived military retirement pay as divisible community property.”

The planning consequence is blunt: a former spouse's share of retired pay can shrink after the divorce, and no indemnification clause can lawfully restore it from the disability money itself. What negotiators can do is price the risk up front — offset with other assets, secure the stream with life insurance, or account for a likely waiver when valuing the pension — rather than discover Howell at enforcement time.

The Survivor Benefit Plan: the one-year trap

Like a private pension's survivor annuity, military retired pay stops at the retiree's death unless survivor coverage exists — here, the Survivor Benefit Plan (SBP). A divorce decree can require former-spouse SBP coverage, but the designation isn't self-executing: if the member doesn't submit the election, the former spouse must request a deemed election, and under 10 U.S.C. §1450(f)(3) the request must be received “within one year of the date of the court order or filing involved.” Miss the window and a lifetime of protection can evaporate on a technicality. The stakes and the drafting logic mirror the survivor-benefit clauses in civilian QDROs — name the coverage, name who pays the premium, and calendar the deadline the day the decree is signed.

The TSP: divided by RBCO, frozen on arrival

The Thrift Savings Plan is the defined-contribution side of a military or federal career, and it divides by its own instrument. The TSP's official guidance is explicit that “the rules for qualified domestic relations orders (QDROs) that apply to private sector plans do not apply to the TSP” — what's needed is a retirement benefits court order that refers to the TSP specifically and states the award as a dollar amount or percentage as of a stated date, the same precision-drafting discipline covered in our model-language guide.

Timing matters more than most people expect: “a valid RBCO requires the TSP to freeze your account, preventing you from taking any new loans or withdrawals until the award is paid out or the order is otherwise resolved,” though contributions and investment changes continue. The payee's share is paid out or rolled over — and because the TSP is a balance-based account, the award math (gains, losses, and any outstanding loans between the valuation date and payment) follows the same logic as a civilian 401(k) split, including the loan questions an order should answer explicitly.
