Military Divorce Retirement Pension Rules: What Changed?
by Grant Marsten - August 2025 | Updated September 2026
Divorce can make retirement planning complicated for anyone. But when one spouse is a member of the U.S. military, dividing retirement benefits can involve an additional layer of federal rules, state family law, and military regulations.
One of the most important changes to understand is the 2017 change to the military retired-pay division rules, commonly referred to as the Frozen Benefit Rule.
The change can affect how a former spouse's share of military retired pay is calculated when the divorce occurs before the service member begins receiving retired pay.
However, the rules are more specific than simply saying that a military pension is "frozen" at divorce. The calculation depends on the date of the divorce, whether the member has retired, the type of retirement, the language in the court order, and other circumstances.
What Is a Military Retirement Pension?
A military retirement pension is a defined benefit based on a service member's military career and applicable retirement system.
Unlike an individual investment account such as an IRA or 401(k), a military retirement pension can provide ongoing monthly retired pay after the member becomes eligible for retirement.
Military retired pay is administered through the appropriate military pay system, with the Defense Finance and Accounting Service (DFAS) responsible for processing many court orders involving military retired pay.
What Is the USFSPA?
The Uniformed Services Former Spouses' Protection Act (USFSPA) is a federal law that provides a mechanism for state courts to treat disposable military retired pay as property in divorce proceedings.
One important point is often misunderstood: USFSPA does not automatically give a former spouse a share of a military pension.
The former spouse generally must receive an award through a qualifying court order or property settlement. State law determines whether and how the pension is treated as marital or community property.
USFSPA also provides a mechanism for DFAS to make certain payments directly to a former spouse when the applicable requirements are satisfied.
What Changed With the 2017 Frozen Benefit Rule?
The National Defense Authorization Act (NDAA) for Fiscal Year 2017 changed the definition of disposable retired pay used for certain divisions of military retired pay.
The law was signed on December 23, 2016. For a divorce or legal separation order that becomes final after that date, when the member has not yet begun receiving retired pay, the calculation can be based on the retired pay the member would have been entitled to using the applicable retired-pay base and years of service at the date of the court order.
That amount is then increased by applicable cost-of-living adjustments between the divorce and the member's retirement.
This is why the change is commonly called the "Frozen Benefit Rule."
The important distinction is that the former spouse's calculation can be tied to the service member's status at divorce rather than automatically benefiting from every promotion or additional year of service that occurs afterward.
A Simple Example of the Frozen Benefit Rule
Imagine a service member divorces after 15 years of creditable service. At the time of divorce, the member holds a particular pay grade and has a particular retired-pay base.
The service member then continues working for another 15 years and eventually retires at a higher rank.
Under the applicable post-2016 rules, the calculation used for the former spouse's share may be based on the member's retirement-pay information at the time of divorce, rather than automatically using the member's higher rank and additional service at retirement.
The actual calculation can be more complicated, particularly for members covered by different retirement systems or Reserve/Guard retirement rules. The language in the divorce order is also critical.
What Does the Frozen Benefit Rule Actually Freeze?
The term "frozen benefit" can be misleading.
It does not mean that the service member's entire military retirement benefit is frozen forever at the date of divorce.
Instead, for qualifying cases, the amount used to calculate the former spouse's share is tied to specific retirement-pay information from the divorce date. DFAS then applies the cost-of-living adjustments permitted under the law.
Future promotions and additional service after the divorce therefore may not increase the former spouse's calculated share in the same way they could under older approaches.
Does USFSPA Require a 50/50 Split?
No.
USFSPA does not establish a mandatory 50/50 division of military retired pay. It also does not require every military pension to be divided.
State law and the divorce agreement or court order determine how the retirement benefit is treated in the divorce.
This is one reason military divorce cases can become highly fact-specific. The same military pension can produce different outcomes depending on the applicable state law and the terms of the settlement.
The 10/10 Rule
The 10/10 Rule is another commonly misunderstood military divorce rule.
Generally, for DFAS to make direct payments to a former spouse for a division of retired pay as property under USFSPA, the marriage must have overlapped at least 10 years of creditable military service.
The 10/10 rule is about direct payment through the military pay system. It does not necessarily determine whether a state court can divide the military pension as part of a divorce settlement.
DFAS also has requirements concerning the wording and content of the court order.
The 20/20/20 Rule
The 20/20/20 Rule concerns certain benefits available to qualifying former spouses.
Generally, the former spouse must have:
- Been married to the service member for at least 20 years;
- Had a service member spouse with at least 20 years of creditable service; and
- Had at least 20 years of overlap between the marriage and creditable military service.
A qualifying former spouse may be eligible for certain military benefits, subject to the applicable requirements.
What About the 20/20/15 Rule?
The 20/20/15 Rule applies to a different set of circumstances.
Generally, it involves a marriage of at least 20 years, at least 20 years of creditable service, and at least 15 years of overlap between the marriage and military service.
Benefits are different from those available under the 20/20/20 rule, so former spouses should not assume that meeting one set of requirements means they automatically qualify for every military benefit.
What Happens to the Survivor Benefit Plan?
The Survivor Benefit Plan (SBP) is another important part of military divorce planning.
SBP can provide continuing income to an eligible beneficiary after the service member dies. In a divorce, a former spouse may be designated as the beneficiary under certain circumstances, including where a court order requires former-spouse coverage.
The timing and wording of the required election can be critical. A divorce agreement should therefore address SBP explicitly rather than assuming the former spouse will automatically remain covered.
How Divorce Can Affect the Service Member
Divorce can substantially change a service member's retirement projection.
The pension may become part of the property settlement, while other assets such as a Thrift Savings Plan account, investment accounts, home equity, or other property may also be divided.
The service member should understand exactly how the court order affects future retirement income before making long-term financial decisions.
A promotion after divorce may also have different consequences for the service member and former spouse depending on the applicable retired-pay division rules.
How Divorce Can Affect the Former Spouse
A former spouse may be depending on a portion of military retired pay as part of their own retirement income.
The former spouse should therefore consider the pension alongside other assets and sources of income rather than treating the military pension as the entire retirement plan.
Potential settlement considerations can include:
- Military retired pay
- Thrift Savings Plan assets
- Other retirement accounts
- Home equity
- Investment accounts
- Other property
- Spousal support or other court-ordered payments
- Future healthcare costs
Why the Divorce Decree Matters So Much
A court order dividing military retired pay needs to contain the information required for DFAS to process it.
For certain post-2016 cases, DFAS requires specific information concerning the member's rank or retired-pay base and years of service at the time of divorce. Reserve and Guard cases can involve additional information such as creditable reserve points.
If the required information is missing, DFAS may not be able to approve the order for payment without clarification.
This is why using generic divorce paperwork without understanding the military retirement provisions can create problems later.
Military Divorce Is a State and Federal Legal Issue
Military divorce does not operate under one single set of rules.
State law governs many aspects of the divorce and property division, while federal law determines how military retired pay can be treated and how DFAS can process certain awards.
The result can also depend on whether the service member is active duty, Reserve, or National Guard, which retirement system applies, whether the member is already retired, and the exact terms of the court order.
Because of these differences, this article is general information and should not be used as a substitute for legal advice.
Practical Steps for Couples Going Through a Military Divorce
- Work with an attorney familiar with military divorce. Military retirement benefits have rules that do not apply to ordinary civilian retirement accounts.
- Determine which retirement system applies. The applicable military retirement system can affect the calculations.
- Identify the date the divorce becomes final. The timing of the divorce can matter when determining which retired-pay rules apply.
- Review the exact court-order language. DFAS has specific requirements for processing military retired-pay division orders.
- Address SBP separately. Survivor benefits can be an important part of the overall settlement.
- Review healthcare and other military benefits. Retirement income is only one part of the financial picture.
- Build separate retirement projections. Both people may need to create a new retirement plan after the settlement.
- Keep copies of all final orders and supporting documents. Retirement benefits can continue for decades after the divorce.
Fun Facts
- The USFSPA became federal law in 1982 and provides a mechanism for certain former spouses to receive a portion of military retired pay.
- The NDAA change associated with the Frozen Benefit Rule was signed on December 23, 2016.
- The 10/10 rule concerns eligibility for certain direct payments through the military pay system; it is not the same thing as a requirement that a court divide the pension.
- A 20/20/20 former spouse may qualify for certain military benefits if all applicable requirements are satisfied.
- Military retired-pay division and Survivor Benefit Plan coverage are separate issues that may both need to be addressed during a divorce.
Final Thoughts
Military retirement pensions can be one of the most significant financial assets in a military divorce. The rules surrounding them are also more complicated than simply dividing a retirement account in half.
The 2017 changes can affect how a former spouse's share of military retired pay is calculated when the divorce occurs before retirement. The USFSPA, state law, the 10/10 rule, healthcare eligibility, and SBP can all play important roles in the final financial picture.
Both the service member and former spouse should understand the retirement consequences before agreeing to a settlement. A military divorce attorney, financial professional, and the appropriate military resources can help clarify the rules that apply to a particular situation.
Once the settlement is known, the next step is to rebuild the retirement plan around the income and assets each person will actually have.
