How is a military pension divided in a divorce?
A military pension divides in divorce the way any other pension does: it is property, your state's division rules apply, and there is no minimum length of marriage. Federal law (the USFSPA) lets state courts treat disposable retired pay as marital property. Almost everything else people believe about it is a myth, and the myths run in both directions.
One condition comes before all of it, and it is where this pension is most often lost: the court has to have the right connection to the service member. That means the member lives in the state for some reason other than being stationed there, is legally domiciled there, or agrees to the case being heard there. Being assigned to a base in the state is expressly not enough, and an order dividing the pension without one of those three is not one the government will honor. Raise it with your attorney before you file anywhere.
The ten-year rule is about the check, not the share
The "10/10 rule" people search for, ten years of marriage overlapping ten years of creditable service, decides one thing only: whether DFAS will pay the former spouse's share directly, instead of the retiree receiving it all and owing the ex their portion. A court can divide the pension after a two-year marriage. Under ten years of overlap just means the payment routes through your ex rather than the government, which is a collection headache, not a lost right.
If someone has told you a short marriage means no pension share, they have confused this rule with the ten-year Social Security rule, which really is a hard eligibility line. Different systems, different rules.
How much: the myth of half
The former spouse's share is capped at 50% of disposable retired pay for direct payment, but what a court actually awards is usually the marital fraction: half of the portion earned during the marriage, not half of the whole pension. Twenty years of service, ten of them married, comes out near a quarter, not a half.
And for members still serving at divorce, the amount is frozen. Under the 2017 change to federal law, the ex's share is computed from the member's rank and years of service at the date of divorce, adjusted only for cost-of-living increases afterward. Promotions and additional years after the decree belong to the member alone. Older advice that assumes the ex shares in post-divorce growth is describing the pre-2017 world.
How the share is written decides whether it keeps up. DFAS adds the annual cost-of-living increases to a share expressed as a percentage, and adds none at all to one written as a flat dollar figure, even where the court order says otherwise. Ask for a percentage.
Remarriage does not end it
The property share survives remarriage, both of you can remarry without touching it. Retired-pay division is a completed property transaction, like splitting a house, not an ongoing benefit. What remarriage does end is different things people conflate with the pension: 20/20/20 TRICARE eligibility, and (before age 55) survivor annuity payments. The pension share itself continues unless your own court order says otherwise.
Years later, and the silent decree
A share the decree awarded does not expire: if it was ordered, it is owed, even if nobody set up direct payment at the time. The harder case is a decree that never mentioned the pension. Reopening a final property division is difficult everywhere, though some states allow a claim to divide an asset the decree simply omitted. If your decree is silent about a pension you knew nothing about, that is a real conversation to have with an attorney, not a lost cause or a sure thing.
The VA disability trap
VA disability pay is not divisible, and this matters more than it sounds. A retiree who waives retired pay to receive disability compensation shrinks the pot the ex's percentage applies to, sometimes years after the divorce, and the Supreme Court has held that state courts cannot order the veteran to make up the difference. That does not always mean the share is gone. A retiree with twenty years of service and a rating of 50% or higher generally draws Concurrent Retirement and Disability Pay, which DFAS treats as retired pay and does divide with a former spouse. The one to watch is Combat-Related Special Compensation, which is not divisible, requires the waiver, and can be switched to during an open season each January, so a decree that says nothing about that election leaves the share exposed to a choice the retiree makes alone every year. The protection is contractual and it has to be built in before the decree is final: indemnification language, or an award structured against other assets. If you are the non-military spouse, raise this with your attorney by name, because it is the single most consequential drafting issue in a military divorce.
Death ends the pension
Retired pay stops when the retiree dies, and the ex-spouse's share stops with it. The only thing that continues is the Survivor Benefit Plan, which has its own unforgiving deadline.
Division runs under state law through the federal USFSPA framework (10 U.S.C. §1408), and the disability rules are Supreme Court law (Mansell, Howell). Military pension division is specialized enough that it is worth asking any attorney you interview how many military divorces they have actually handled.
