Military Divorce Retirement Pay: 10/10 Rule, Frozen Benefit Calculator

Military retired pay is often the largest asset in a military divorce, and it runs on federal rules most state family courts apply only at the edges. The Uniformed Services Former Spouses’ Protection Act, 10 U.S.C. § 1408, lets a state court treat retired pay as property “in accordance with the law of the jurisdiction of such court.” Then it sets the limits: how much, which pay, who sends the check, and what the order must say before DFAS will honor it. Every rule below was read in the U.S. Code and on DFAS’s own pages in October 2026.

Military retirement divorce calculator

For a divorce final before the member retires. Federal law freezes the divisible pay at the member's High-3 and years of service on the date of the decree, then adds cost-of-living raises. Enter the numbers as of that date.

Monthly High-3 at the decree ($) Years of service at the decree Retirement system High-3 (2.5% a year) Blended Retirement System (2% a year) Years married while serving Spouse's award of the marital share (%) Total years married (for 20/20/20)

Estimate in today's dollars, before cost-of-living raises. The marital fraction (years married while serving divided by years served at the decree) is the most common state formula, but your state court sets the formula, and the order controls. Leaves out REDUX, disability retirement, Reserve points, and any VA disability waiver, which lowers the divisible pay. Not legal advice.

The frozen benefit rule: the divorce date fixes the number

Before 2017, many courts divided the member’s eventual retired pay, including raises and promotions earned years after the divorce. Congress ended that for any decree that becomes final after December 23, 2016. Under § 1408(a)(4)(B), when the divorce is final before the member retires, the divisible retired pay is the amount the member “would have been entitled” to using the member’s retired pay base and years of service “on the date of the decree,” increased by the cost-of-living adjustments between the decree and retirement and after it.

In practice: a member divorced at 14 years with a $6,000 monthly High-3 has a frozen benefit of 35% of $6,000 under the legacy High-3 system (2.5% a year under § 1409(b)), which is $2,100 a month before COLAs. Under the Blended Retirement System the multiplier is 2% a year (§ 1409(b)(4)), so the same facts give $1,680. Whatever the member earns by serving to 20 or 30 years belongs to the member.

The marital share then depends on state law. The common formula is the years married while serving divided by the years served at the decree. With 10 years of overlap out of 14, that is 71.4% of $2,100. A 50% award of that marital share is about $750 a month, which is what the calculator above shows on its default numbers.

For the order to work, it has to carry the inputs the statute uses: the member’s High-3 and years of service (or Reserve retirement points) on the decree date. DFAS’s FAQ is blunt about vague wording: the order “must provide enough information to enable DFAS to compute the amount of the award,” and awards such as “50 percent of the marital portion of military retired pay” “do not suffice.” DFAS sends those back, and the former spouse has to return to court for a clarifying order. DFAS points to Appendix A of Chapter 29 of the DoD Financial Management Regulation, Volume 7B, for acceptable language.

The limits federal law puts on every award

The jurisdiction rule surprises people. A member stationed in a state is not resident there for this purpose “because of military assignment.” To divide the retired pay, the divorce court needs the member’s legal residence, domicile, or consent. Filing where you happen to be stationed can produce a divorce that is valid on everything except the pension.

The VA rule is the other trap. A member who later takes VA disability compensation must waive the same amount of retired pay, and the waived amount drops out of disposable retired pay, which can shrink the former spouse’s share after the fact. Settlements that anticipate it say so in the decree.

Where the SCRA comes in

DFAS will not pay on an order just because a court signed it. Section 1408(b)(1)(D) makes service of a court order effective only if the order or the documents served with it “certify that the rights of the member under the Servicemembers Civil Relief Act … were observed.” DFAS’s application page says it reviews every order to determine whether the SCRA and the USFSPA’s jurisdictional and 10/10 requirements have been met.

That links the pension directly to how the divorce was run. A divorce pushed through by default against a member who was deployed and never appeared, with no SCRA affidavit and no appointed attorney, is the kind of order DFAS can refuse, and the member can move to reopen under 50 U.S.C. § 3931(g). The safe paths are a member who appears or signs a written waiver, or a court that followed the SCRA’s affidavit and stay rules. The court side, including how to divorce or be divorced while deployed, is in the SCRA divorce and custody guide.

Survivor Benefit Plan: the one-year deadline

The retired pay award ends when the member dies. Survivor Benefit Plan coverage is what keeps a former spouse paid after that, and it runs on a strict clock:

• The member’s deadline. A retired member who covers a spouse and is ordered to cover the former spouse must send a written, signed election that DFAS receives “within one year after the date of the decree” (10 U.S.C. § 1448(b)(3)(A)(iii)).
• The former spouse’s backstop. If the member does not, the former spouse can send DFAS a written request for a “deemed election” with a copy of the court order. DFAS must receive it “within one year of the date of the court order” (§ 1450(f)(3)(C)).

A former spouse who misses that year can lose SBP coverage even when the decree requires it. Calendar the date the decree is signed.

20/20/20: keeping TRICARE and base privileges

Under 10 U.S.C. § 1072(2)(F), an unremarried former spouse married to the member for at least 20 years, during which the member performed at least 20 years of creditable service, and who “does not have medical coverage under an employer-sponsored health plan,” counts as a dependent for military benefits such as TRICARE, commissary, and exchange privileges. A 19-year overlap does not qualify, which is why the timing of a decree near the 20-year mark matters to both sides.

How a former spouse applies to DFAS

Apply for direct payment from DFAS

1. Get a copy of the final decree and any property settlement certified by the clerk of court. DFAS accepts a photocopy of the certified order.
2. Check the order states the member’s High-3 and years of service (or retirement points) on the decree date, the award as a percentage or formula, and the SCRA certification.
3. Complete DD Form 2293, Application for Former Spouse Payments From Retired Pay, and sign it.
4. Send both to DFAS Garnishment Law Directorate, P.O. Box 998002, Cleveland, OH 44199-8002, by fax to 877-622-5930 (toll free), or online through Garnishment askDFAS. Include the member’s Social Security number on every page; DFAS says documents without it will not be processed. DFAS’s phone line is 888-332-7411.
5. If the decree requires SBP coverage, send the deemed election request within one year of the order, separately from the payment application.

What this page is not

It is not a prediction of what a court will award. Federal law sets the ceiling, the frozen inputs, and the payment rules; the share inside those limits is state law, and some states use formulas other than the marital fraction. A decree that became final on or before December 23, 2016 is not frozen. REDUX, disability retirement, and Reserve retirement computed by points work differently from the active-duty High-3 and BRS math in the calculator. Take the numbers to a family law attorney in your state, or to your installation legal assistance office if you are a servicemember or dependent.
