A military pension in divorce gets locked in at the decree date for members still serving, so First Command Financial Services checks three items early: the frozen share, the SBP premium and the TSP-3. Picture the kitchen table on the evening the attorney's draft settlement arrives, with the retired-pay clause still showing a blank where the High-3 should be. If you do nothing, that blank gets filled by whatever the draft or DFAS (the Defense Finance and Accounting Service) fills in, and the 1-year deadlines for the Survivor Benefit Plan (SBP) and the Thrift Savings Plan (TSP) beneficiary form pass without a filing.

Run the budget on the net pension, not the gross. If $4,222 is what lands each month, that's the number every other decision has to fit.

The decree date sets the pension number
Three beliefs about a military pension in divorce travel through break rooms, and each one misleads.
'Under 10 years of marriage means no share.' Wrong. The Uniformed Services Former Spouses' Protection Act lets a state court divide disposable retired pay (your pension after certain deductions) with no minimum marriage length. The 10/10 test, 10 years of marriage overlapping 10 years of service, only decides whether DFAS pays the former spouse directly.
'The ex automatically gets half.' Also wrong. No federal percentage exists, so the state court sets the share. DFAS caps direct payments at 50% of disposable retired pay for property. If garnishments for child support and alimony are layered on top, the combined ceiling rises to 65%.
'Every promotion raises the ex's cut.' For decrees final after December 23, 2016, it doesn't. The share is frozen at your High-3 (the average of your highest 36 months of base pay) and your years of service at the decree date, then rises only with retiree cost-of-living adjustments until you retire.
The 2.5%-per-year math has exceptions. A member already retired at the decree has actual retired pay divided, not a frozen figure. Guard and Reserve members are measured in reserve points. Blended Retirement System members use a 2.0% multiplier. And if the marriage overlapped fewer than 10 years of service, you pay the former spouse yourself each month.
Some things are hard to undo. A decree that leaves out the High-3 and the years (or points) at the decree date can stall DFAS processing for months. Before mediation, pull your High-3 estimate and your service-credit count, and ask the attorney to write both numbers into the order.
VA disability compensation can't be divided as property. Any retired pay you give up to collect it no longer counts as disposable retired pay. A percentage award can therefore shrink later, which is a downside for the former spouse and a source of future conflict. State law decides how the pension is divided, and none of this replaces a family law attorney.
Three beliefs and where each goes wrong
Where the 2.5% math stops working
How long do you have to file the SBP election and new TSP-3?
You have 1 year from the divorce to make a court-ordered SBP former-spouse election. If you miss it, the former spouse can request a deemed election, and that request must reach DFAS within 1 year after the court order is issued.
The TSP-3 beneficiary form doesn't change when a divorce becomes final, so the Thrift Savings Plan still pays whoever is named on it. File the new TSP-3 in the same week as the SBP paperwork. Both forms cost nothing to file, and both are among the hardest things to repair once a deadline passes or a death occurs.
How much of a $5,500 pension is left after the split?
Of a $5,500 gross pension, Reena keeps $4,222 each month after a $1,200 former-spouse share and a $78 SBP premium, or $50,664 each year. The calculator on this site runs the same steps with your own High-3, years and award.
$12,000 estimated tax savings
Hypothetical estimate for illustration only.
A hypothetical couple, Reena and Bao, carry an older divorce into retirement. Reena, 49, retires as an Air Force lieutenant colonel after 22 years. Bao, 51, is a civilian ICU nurse. They hold about $700,000 across the TSP and traditional IRAs, and Reena plans a 9-month break before her next job. Her first divorce became final at 43, after 16 years of service, 12 of them during that marriage, so the 10/10 test was met.
Step 1: High-3 times 2.5% times years at the decree. With a $6,250 High-3, 16 years is 40%, so $2,500 a month. Step 2: multiply by the award. Her ex got 40%, or $1,000. Step 3: add retiree COLAs, assumed at 20% for illustration, which makes $1,200. Step 4: at 49 her pension is 22 × 2.5% = 55% of a $10,000 High-3, or $5,500. Subtract $1,200 and the 6.5% SBP premium on a $1,200 base ($78), and $4,222 is left.
Find the last row first: if Reena dies before her former spouse, the ex receives $660 and Bao receives nothing.
Agreeing at the decree to former-spouse SBP on the full retired pay costs $0 that year, because no premiums are due before retirement. At 49 it would cost 6.5% × $5,500 = $357.50 each month ($4,290 each year) instead of $78, and Bao still couldn't be covered.
When DFAS pays the former spouse directly, the $1,200 goes on the former spouse's own Form 1099-R, not Reena's. SBP premiums are excluded from her taxable retired pay, which leaves $50,664 in her gap year, plus Bao's ICU salary, before the $32,200 married-filing-jointly standard deduction (the IRS figure for 2026). If the 10/10 test isn't met and she pays privately, the full pension appears on her 1099-R, and a CPA has to sort out the reporting.
Before First Command Financial Services builds the gap-year budget, it has Reena set aside the first 6 months of the $1,200 share and the premiums as fixed bills, so a slump in the TSP's C Fund never forces a sale to cover them. TSP and IRA balances can fall, and money sold in a down year can come back as less than was put in. How much to convert to Roth that year belongs on the Roth conversion strategy page.
The four-step math
A choice that costs nothing this year
What the 1099-R shows
Quick test before you sign: gross pension minus the former-spouse share minus the SBP premium. If that monthly number is below your fixed bills, negotiate the SBP base or the TSP split first. A final decree is far harder to change than a draft.
| Reena's age | What happens | What to do |
|---|---|---|
| 43, decree final | Frozen pay set at $2,500 | Write High-3 and years into order |
| By 44 | 1-year SBP former-spouse deadline | File election and new TSP-3 |
| 49, retires | DFAS pays ex $1,200 each month | Budget on $4,222, not $5,500 |
| 49–50, gap year | Taxable retired pay about $50,664 | Confirm 1099-R split before converting |
| Any later VA rating | Waived pay leaves disposable pay | Ask attorney about state remedies |
| At Reena's death | Ex gets $660; Bao none | Price term life for Bao |
Later years can still move the numbers
Retirement year brings its own traps. Sizing a Roth conversion before DFAS direct payments to the ex have started can backfire, because the first months may land as full pay on Reena's 1099-R and push taxable income above the estimate. First Command Financial Services advisors ask for the first retiree account statement before sizing any conversion. A VA rating granted after retirement also reduces disposable retired pay, so ask the attorney now how the state treats that change. Federal law bars dividing the compensation itself.
SBP gets tricky after remarriage. While former-spouse coverage stays in place, Reena can't elect spouse coverage for Bao, and changing it generally takes a modified court order. If the former spouse remarries before age 55, the annuity is suspended. Term life insurance for Bao is the usual hedge, and the SBP vs. life insurance comparison covers that choice.
The table sets the two SBP bases Reena could have agreed to side by side.
Bring these questions to the family law attorney, the CPA and DFAS:
| Feature | Base on $1,200 share | Base on full $5,500 |
|---|---|---|
| Monthly premium | $78 | $357.50 |
| Yearly premium | $936 | $4,290 |
| Annuity to ex if Reena dies | $660 | $3,025 |
| Cost in decree year | $0 | $0 |
| SBP spouse coverage for Bao | Blocked while ex covered | Blocked while ex covered |
- Does the order state the High-3 and years (or points) at the decree date?
- Is the SBP base the $1,200 share or the full retired pay?
- Who files the SBP election, and by what date?
- How will the first year's 1099-Rs split the pension?
- What happens to the share if a VA waiver starts?
- Has the TSP-3 been updated, and is there a retirement benefits court order for any TSP split?
Questions about a military pension in divorce
My decree gives my ex 40% of my retired pay and the VA just raised my rating; will her payment shrink?
It can. VA disability compensation can't be divided as property, and retired pay waived to receive it drops out of disposable retired pay. If the order awards a percentage of disposable pay, her payment falls as the waiver grows. Ask your attorney how your state handles that change.
Why would I need a financial planner if my divorce attorney already wrote the pension clause?
The attorney writes the clause; a planner tests whether your budget works after it. That means turning the share, the SBP premium and taxes into one monthly number, setting cash aside so the TSP isn't sold in a bad year, and pricing life insurance for a new spouse.
When does my former spouse's pension share stop growing?
For decrees final after December 23, 2016, the share is frozen at your High-3 and years of service (or points) at the decree date. After that it rises only with retiree COLAs until you retire. Later promotions and extra years don't raise it. Older decrees may differ, so check the wording.
Is it better to give my ex more of the TSP so the pension stays whole?
Sometimes, but it trades money that can fall for a steady lifetime paycheck. A bigger TSP split keeps your monthly pension higher, yet a bad market year then hits your own account. Run both versions as monthly budgets first, and confirm the TSP split needs its own court order.
Where First Command Financial Services fits once the order is signed
Households bring the signed decree, a retired-pay estimate and the latest TSP and IRA statements to a first conversation by video or telephone. First Command Financial Services then turns those figures into a written plan that shows the monthly budget after the split and the cash set aside so the TSP isn't sold in a bad year. The exact cost is in a written agreement the household reads before any work begins.
Agreeing to former-spouse SBP on the full retired pay costs $0 in the year of the decree, and $4,290 a year once you retire.
