Dividing a Military Pension in a Montana Divorce

Federal Law Controls Military Pension Division

Dividing military retirement pay in a Montana divorce involves an extra layer of complexity because federal law — the Uniformed Services Former Spouses' Protection Act (USFSPA) — governs how military pensions can be split. Montana's own equitable distribution statute (MCA § 40-4-202) determines whether and how much of the pension is divisible, but DFAS (the Defense Finance and Accounting Service) is the entity that actually processes the division, and DFAS follows its own regulations.

The intersection of state and federal rules creates traps that don't exist with civilian retirement accounts. A QDRO won't work for military pensions. The division order has to conform to DFAS requirements, and even small drafting errors can result in rejection.

What's Divisible and What's Not

Under the USFSPA, Montana courts can treat military retired pay as marital property subject to division. The key distinctions:

Disposable retired pay. This is the amount DFAS uses for direct property payments — gross retired pay minus authorized deductions. Those deductions can include amounts waived to receive VA disability compensation and Survivor Benefit Plan (SBP) premiums, among other statutory deductions; federal tax withholding is not an authorized deduction for this calculation. The court order must state the award in terms DFAS can divide.

VA disability compensation. VA disability pay is the service member's separate property and cannot be divided by a state court. This is a federal protection under 38 U.S.C. § 5301. If a military retiree waives a portion of their retired pay to receive VA disability (which is tax-free), the former spouse's share of disposable retired pay shrinks. This is one of the most common sources of post-decree disputes in military divorces.

Combat-Related Special Compensation (CRSC). Like VA disability, CRSC is not divisible.

Concurrent Retirement and Disability Pay (CRDP). CRDP restores some of the retired pay that was waived for VA disability, but only for retirees with 50% or greater disability ratings. CRDP is generally treated as disposable retired pay and can be divided.

The 10/10 Rule Explained

The 10/10 rule determines whether a former spouse can receive direct property payments from DFAS. If the marriage overlapped with at least 10 years of creditable military service, DFAS may send the former spouse their court-ordered share directly after a qualifying application is approved. If the overlap is less than 10 years, the former spouse still has a legal right to their share of the pension — but they have to collect it from the service member, not from DFAS.

The practical difference is significant. Direct payment from DFAS is a collection mechanism that requires a qualifying order and application. Collecting from an ex-spouse requires enforcement through contempt proceedings if payments stop.

Note that the 10/10 rule is about direct payment mechanics only. It does not affect whether the pension is divisible. A Montana court can award a former spouse a share of military retired pay regardless of the length of the marriage. The question is simply who writes the check.

How Much the Former Spouse Gets

USFSPA caps the maximum amount DFAS will pay directly to a former spouse at 50% of disposable retired pay. The actual percentage awarded is determined by the Montana court based on the equitable distribution factors in MCA § 40-4-202.

The most common approach is the coverture fraction, which calculates the marital share of the pension:

Marital months of service ÷ total months of service × 50% (or the court-ordered percentage)

For example, if the service member served 20 years (240 months) and the marriage lasted 15 of those years (180 months), the coverture fraction is 180/240 = 75%. The former spouse's share would be 75% × 50% = 37.5% of disposable retired pay.

Some couples use a fixed dollar amount instead of a percentage. This provides certainty but doesn't account for future cost-of-living adjustments (COLAs), which increase military retired pay annually. A percentage-based award automatically includes COLAs; a fixed-dollar award doesn't.

The Survivor Benefit Plan: Critical and Often Overlooked

The Survivor Benefit Plan (SBP) is a federal annuity program that provides a monthly payment to a surviving beneficiary after the retiree's death. Without SBP coverage, the former spouse's pension payments stop the day the retiree dies — even if the former spouse was supposed to receive payments for life.

Election deadlines matter. SBP coverage for a former spouse must be elected within one year of the divorce decree. If the decree requires coverage, the former spouse can make a "deemed election" by requesting it from DFAS with a copy of the court order, but that request must also be submitted within one year of the order requiring coverage. The decree should explicitly require the service member to elect former-spouse SBP coverage.

Cost. SBP premiums are 6.5% of the covered amount, deducted from the retiree's gross retired pay before the disposable retired pay calculation. This cost is negotiable — some agreements split the premium, while others assign it entirely to one party.

The payout. If the retiree dies, the former spouse receives 55% of the SBP-covered amount for life. Without SBP, they receive nothing.

Drafting the Military Pension Division Order

DFAS has specific format requirements for pension division orders. The order must include:

• The service member's full name, Social Security number, and branch of service
• The former spouse's full name, Social Security number, and mailing address
• The specific amount or percentage of disposable retired pay awarded
• Whether the award includes COLAs
• Whether SBP coverage is ordered
• Language specifying that the court has jurisdiction under the USFSPA

DFAS reviews every order for compliance before processing it. Common reasons for rejection include using QDRO language (which applies to ERISA plans, not military pensions), failing to specify disposable retired pay (instead of gross), and omitting the jurisdictional language.

After the order is entered by the Montana District Court, the former spouse submits it to DFAS along with DD Form 2293 (Application for Former Spouse Payments). Processing typically takes 30 to 90 days.

Coordinating with the Rest of Your Property Division

Military pension division doesn't exist in isolation. The value of the pension share affects the overall equalization of your marital estate. If one spouse is receiving a significant portion of the other's military retired pay, that value should appear on the MP-500 Proposed Property Distribution and factor into the four-column ledger that balances the total split.

The Montana Divorce Financial Split & Asset Division Guide covers both civilian retirement division (QDROs and Montana FLOs) and the military pension framework, with worksheets that help you calculate coverture fractions and integrate pension values into your overall property division.
