A military pension can represent twenty or more years of a service member’s career, and in many military marriages it dwarfs every other asset on the balance sheet. When that marriage ends, dividing the pension correctly requires navigating Tennessee equitable distribution law alongside multiple layers of federal statute, including rules that changed significantly in 2016 and 2017. Getting even one piece wrong can cost the non-military spouse thousands of dollars a year in retirement income or leave them without death benefit protection entirely.
I’ve helped Williamson County families work through military divorce cases since 1988. In that time, I’ve seen the same misconceptions surface repeatedly: that a short marriage means the pension can’t be divided, that VA disability pay is just another form of retirement income, that one court order covers everything. None of those assumptions hold up under current law. What follows is a plain-language explanation of how Tennessee courts actually approach military retirement assets, and where the process most often goes wrong.
How Tennessee Law Treats Military Retirement as Marital Property
Military retired pay wasn’t always divisible in divorce. The Uniformed Services Former Spouses’ Protection Act (USFSPA), codified at 10 U.S.C. § 1408 and enacted in 1982, is the federal statute that grants state courts authority to treat military retirement pay as marital property subject to division. Without it, a service member’s pension would be entirely off the table regardless of how long the marriage lasted.
Tennessee operates under equitable distribution principles established in Tenn. Code Ann. § 36-4-121. Courts divide marital assets fairly, which typically starts close to a 50/50 split and adjusts based on statutory factors like the length of the marriage, each spouse’s earning capacity, and contributions to the household. Only the portion of the retirement that accrued during the marriage is subject to division. Service time before the wedding date is the service member’s separate property and stays that way.
The 10/10 Rule: What It Actually Means
The 10/10 rule is probably the most widely misunderstood concept in military divorce. Many spouses assume it determines whether the pension can be divided at all. It doesn’t. The rule has exactly one function: it governs who writes the check.
When a marriage overlapped at least ten years of creditable military service, DFAS (the Defense Finance and Accounting Service) can pay the former spouse’s share directly. When that threshold isn’t met, the former spouse still has a court-enforceable right to a share of the pension. The service member just pays it personally rather than DFAS paying it automatically. Both the marriage duration and the service overlap are measured from the date of marriage to the date of divorce, not the date of separation.
The Frozen Benefit Rule & How It Changed the Math
For divorces involving active-duty service members, a 2016 federal law fundamentally changed how the divisible share is calculated. The National Defense Authorization Act for Fiscal Year 2017, signed December 23, 2016, introduced what practitioners call the frozen benefit rule: when a service member is still on active duty at the time of divorce, the former spouse’s share is calculated using the service member’s rank and years of service as of the divorce date, not the eventual retirement date.
Before this rule, a formula called the marital fraction applied the percentage of marriage-to-service overlap against whatever the service member ultimately retired at, meaning post-divorce promotions partially benefited the former spouse. The frozen benefit rule ends that. Any rank increases or additional service years earned after the divorce belong entirely to the service member. The former spouse’s portion can still receive cost-of-living adjustments over time, but the base is locked at divorce-date grade and service. This rule applies to divorces finalized after December 23, 2016; cases where the service member was already receiving retired pay at the time of divorce aren’t affected.
VA Disability Pay & the Howell v. Howell Risk
VA disability compensation isn’t divisible marital property under federal law. When a service member waives a portion of military retirement pay to receive VA disability benefits, the waived amount is removed from the pool of disposable retired pay available for division. This matters more than most people anticipate at the time of divorce.
In Howell v. Howell, decided unanimously by the U.S. Supreme Court on May 15, 2017, the Court held that state courts can’t order a veteran to reimburse a former spouse for any reduction in pension payments caused by a post-divorce VA disability waiver. It doesn’t matter what the original divorce decree says. If the service member later applies for and receives VA disability compensation and the corresponding retirement pay is reduced, the former spouse absorbs that loss. Tennessee courts can’t undo it.
This risk can be addressed during settlement. Options include negotiating indemnification language (which carries collection risk but creates a legal remedy), adjusting the overall asset division to account for the possibility of future waivers, or structuring alimony in a way that partially offsets the exposure. None of these solutions is perfect, but none of them are available after the decree is signed.
The Survivor Benefit Plan, the TSP, & Why Both Need Their Own Decree Language
The pension itself is only part of the financial picture. Two other assets require separate attention in every military divorce settlement.
Survivor Benefit Plan (SBP)
The Survivor Benefit Plan is a premium-based annuity that continues payments to a named beneficiary after the service member dies. In a military divorce, the former spouse can be named as the SBP beneficiary, but DFAS must be notified of the former spouse election within one year of the court order providing for SBP coverage. Miss that window and the opportunity is permanently gone, regardless of what the decree says. Because many service members outlive their former spouses by decades, this is either a significant financial protection or a significant gap depending on whether the deadline is met.
Thrift Savings Plan (TSP)
The Thrift Savings Plan is a defined-contribution retirement account, functionally similar to a 401(k), and it’s completely separate from the pension. It requires its own court order that can’t be folded into the Military Pension Division Order (MPDO). The TSP uses its own formula based on contributions and earnings during the marriage, and the order must meet TSP-specific requirements to be accepted by the TSP Service Office.
DFAS rejects orders with any of several common drafting errors: QDRO or ERISA language (which applies to private-sector plans, not military retirement), missing formulas or percentages for calculating the former spouse’s share, and failure to identify the service member by full legal name, Social Security number, and branch of service. A rejected order means going back to court, which adds time and cost.
Immediate Offset vs. Deferred Distribution
Tennessee courts recognize two structural approaches to dividing a military pension, and the right choice depends on what else is in the marital estate.
Immediate Offset
Immediate offset assigns the pension a present-value dollar amount today. The non-military spouse receives other marital assets of equivalent worth and the parties have no further financial connection through the pension. This approach works well when the marital estate includes significant non-pension assets like home equity, investment accounts, or a civilian retirement plan. The risk is that actuarial present-value calculations involve assumptions about life expectancy and discount rates that may not reflect what actually happens.
Deferred Distribution
Deferred distribution applies the marital fraction directly to each monthly pension payment once the service member retires. The former spouse receives a percentage for as long as retirement benefits are paid. When the pension is the primary or only significant marital asset, this is typically the only realistic option. One important drafting note: fixed-dollar DFAS awards don’t increase with cost-of-living adjustments, so a $600-per-month award today buys far less purchasing power in fifteen years. Percentage-based awards carry cost-of-living adjustments and are generally more protective for the former spouse over the long term.
Filing in Williamson County
Military divorce cases in Franklin are filed in the Williamson County Circuit Court or Williamson County Chancery Court, both located at the Judicial Center at 135 4th Ave South, Franklin, TN 37064. Williamson County sits in Tennessee’s 21st Judicial District, where the same judges sit as Chancellor when holding Chancery Court. Which court handles a given case depends on the specific issues involved, and both courts have authority to enter orders dividing military retirement benefits under USFSPA.
The intersection of Tennessee equitable distribution law, USFSPA, the frozen benefit rule, Howell v. Howell, TSP requirements, SBP deadlines, and DFAS order drafting requirements makes military pension division one of the most technically demanding areas of family law. A single drafting error or missed deadline can have permanent financial consequences. If you’re facing a military divorce in the Franklin area and want to understand your options, Julia E.
