Federal Employee Divorce: FERS Annuity, TSP, FEHB, and FEGLI
Divorce is more complex for federal employees than for most workers. Your pension, TSP, health insurance, and life insurance each operate under separate federal rules — and private-sector QDRO attorneys often get them wrong. This guide explains how each benefit stream is actually divided.
How divorce affects federal benefits: the four streams
| Benefit | Governing rule | What can be divided |
|---|---|---|
| FERS / CSRS annuity | 5 CFR Part 838 (OPM COAP) | Share of monthly annuity + court-ordered survivor annuity |
| TSP account | 5 CFR Part 1653 (TSP RBCO) | Portion of account balance or future contributions |
| FEHB health coverage | 5 U.S.C. § 8905a (TCC) | Former spouse gets TCC up to 36 months at 102% premium |
| FEGLI life insurance | 5 U.S.C. § 8706 | Beneficiary designation only — assignment limited |
1. FERS annuity division — the OPM court order
Under 5 CFR Part 838, a state court can divide a FERS or CSRS pension by issuing a Court Order Acceptable for Processing (COAP).1 Unlike ERISA plans where a QDRO directs the plan administrator, OPM acts as its own administrator and applies specific acceptability standards to every order it receives.
What OPM requires
To be "acceptable for processing," a COAP must:1
- Specify the former spouse's benefit using only information OPM can compute from its own files (no external court decisions or state statutes)
- Express the award as a fixed dollar amount, a percentage of the annuity, or a self-contained formula
- Permit OPM to collect the annuity reduction required by 5 U.S.C. § 8419 (for FERS survivor annuity cost) from the employee's annuity
- Not use ERISA QDRO language — an order styled as a QDRO is not acceptable for federal retirement benefits
Marital fraction formula — how courts typically divide the annuity
The most common approach is a "marital service fraction" formula. The court specifies the percentage of the total annuity attributable to federal service that occurred during the marriage, then awards the former spouse a share of that fraction. A well-drafted order might read:
"Former spouse shall receive 50 percent of the marital share of participant's CSRS/FERS annuity. The marital share is a fraction, the numerator of which is the number of months of participant's creditable federal service performed during the marriage (from date of marriage to date of divorce), and the denominator of which is the total number of months of participant's creditable federal service at retirement."
For a GS-14 with 28 years of total service and 18 years of marital service, this yields a marital fraction of 18/28 = 0.643. The former spouse's share under a 50% award would be: 0.643 × 50% = 32.1% of the total annuity. On a $40,600/yr annuity, that is roughly $13,050/yr paid directly by OPM to the former spouse once the employee retires.
Court-ordered survivor annuity (COSA)
Separately, the court can order that the former spouse receive a survivor annuity — meaning the former spouse continues to collect after the employee dies. Under FERS (5 U.S.C. § 8419), a court-ordered survivor annuity costs the employee the same 10% annuity reduction (for a full, 50% survivor benefit) or 5% reduction (for a partial, 25% benefit) as a voluntarily elected survivor annuity.2
Critical difference from a voluntary election: a court-ordered survivor annuity cannot be removed later, even if the employee remarries. If you have a COSA in your divorce decree, your annuity will be reduced for life. A voluntary survivor annuity election, by contrast, can be changed upon remarriage.
If the employee dies before retiring, a former spouse who was awarded a COSA by court order is entitled to a survivor annuity based on the employee's projected benefit at time of death, provided the court order was filed with OPM before death. This is why submitting the COAP to OPM promptly after divorce matters.
FERS supplement — can it be divided?
The FERS Special Retirement Supplement (paid from retirement until age 62) is part of the FERS annuity and can in principle be subject to a COAP. However, the supplement terminates unconditionally at age 62 regardless of any court order. Any award based on the supplement simply stops. A well-drafted settlement should address this cliff explicitly — particularly if the former spouse is relying on that income stream.
2. TSP division — the Retirement Benefits Court Order (RBCO)
The Thrift Savings Plan is a defined contribution plan, but it is not subject to ERISA — which means the standard QDRO process does not apply. To divide a TSP account, the court must issue a Retirement Benefits Court Order (RBCO) that meets the requirements of 5 CFR Part 1653.3
RBCO vs. QDRO: the critical distinction
Family law attorneys who handle private-sector divorces regularly use QDRO language and templates. Those do not work for TSP. TSP's rules require the order to:3
- Expressly refer to the TSP account (not a "pension plan" or "defined benefit plan")
- Award a specific dollar amount or a percentage of the account balance as of a specific date, not a formula tied to future benefits
- Identify whether it applies to the civilian TSP account, the uniformed services account, or both (if the employee has both)
- Not use language appropriate only for a defined benefit plan (benefit formulas, retirement income percentages, etc.)
An order filed as a QDRO will not be processed. This is one of the most common errors in federal employee divorces — the attorney uses a QDRO template, TSP rejects it, and years can pass before anyone realizes the account was never actually divided.
How TSP pays the former spouse
Once TSP approves the RBCO, it creates a separate TSP account (or issues a direct payment) to the former spouse. The former spouse can keep the funds in TSP under their own account, roll them over to an IRA or eligible plan, or take a taxable distribution. Importantly: the 10% early withdrawal penalty does not apply to RBCO distributions taken directly from TSP — the same tax break as with QDRO-derived distributions from private plans.
What the RBCO cannot do
An RBCO can only divide the account balance that exists at the time the order is processed. It cannot require the employee to make future contributions, change investment elections, or otherwise alter future TSP behavior. It also cannot divide the TSP loan balance — outstanding TSP loans must be resolved separately.
3. FEHB after divorce — coverage for the former spouse
When a divorce is finalized, the former spouse loses FEHB coverage. The employee continues their own coverage (usually changing from "self and family" to "self only" or "self and family" if dependent children remain enrolled). The former spouse has two primary options:4
Option A: Temporary Continuation of Coverage (TCC)
Under 5 U.S.C. § 8905a, former spouses who were covered by the employee's FEHB family enrollment for at least 18 months before the divorce may elect TCC — continuing the same FEHB plan for up to 36 months.4 Cost: the full premium (both the employee's share and the government's share) plus a 2% administrative charge. This is typically two to four times more expensive than what the employee pays.
The notification window is 60 days after the divorce is final. Both the employee and former spouse share responsibility for notifying the employing office within that window. Missing the 60-day deadline eliminates the TCC option entirely.
Option B: Spouse equity enrollment
If the divorce decree awards the former spouse a court-ordered survivor annuity or a portion of the employee's annuity, the former spouse may qualify for "spouse equity" FEHB enrollment — enrolling in FEHB on their own, independent of TCC. Spouse equity enrollment continues for life (not just 36 months) but requires the former spouse to pay the full premium and requires the court order to be on file with OPM. This is a better long-term solution than TCC for former spouses who will not otherwise have access to employer-sponsored coverage.
FEHB upon the employee's death
If the employee dies after retirement and the former spouse was receiving a court-ordered survivor annuity, the former spouse's FEHB coverage (whether through spouse equity or TCC) can continue under the survivor annuity. If there is no survivor annuity in place, FEHB ends when the employee dies.
4. FEGLI life insurance after divorce
FEGLI does not automatically update upon divorce. The beneficiary designation on file with OPM (SF-2823) controls where death benefits go — regardless of what a divorce decree says. If the employee dies before updating their designation, the ex-spouse named as beneficiary receives the proceeds even if the divorce decree purports to strip that right.5
Action item: update SF-2823 as soon as possible after the divorce is final. Unlike TSP (which has a statutory default order that prioritizes the current spouse), FEGLI has no automatic spouse default — the named beneficiary on file governs.
FEGLI assignment is generally not available to private individuals in the context of divorce. Courts cannot order the employee to maintain FEGLI coverage for the benefit of the former spouse in the way a QDRO can earmark 401(k) assets. However, courts often address this by requiring the employee to carry a specified amount of private life insurance or by using the survivor annuity as a substitute income-protection mechanism.
Social Security for divorced federal employees
FERS employees fully participate in Social Security, and the standard divorced-spouse SS rules apply. If the marriage lasted at least 10 years, the former spouse may claim up to 50% of the federal employee's Social Security benefit at the employee's full retirement age — without reducing the employee's own benefit.6
Eligibility rules for the former spouse:6
- Marriage lasted ≥10 years
- Former spouse is currently unmarried
- Former spouse is at least 62
- The divorce has been final for ≥2 years (former spouse can claim without waiting for employee to file)
CSRS and the WEP/GPO repeal: CSRS employees historically received little or no Social Security benefit due to the Windfall Elimination Provision, and ex-spouses of CSRS employees received little or no ex-spousal benefit due to the Government Pension Offset. The Social Security Fairness Act, signed January 2025, repealed both WEP and GPO effective for January 2024 and later benefits.7 Former spouses of CSRS employees who had been blocked by GPO should now consult SSA to determine their restored benefit.
Alimony and federal tax treatment
For divorces finalized after December 31, 2018, alimony is no longer deductible by the paying spouse and no longer includible in the recipient's taxable income (TCJA § 11051).8 This changes the negotiation math significantly: a $2,000/month alimony payment under a post-2018 divorce has exactly the same after-tax cost to the payer as $2,000/month in any other expenditure — there is no deduction to offset it.
Pre-2019 divorce agreements that were not modified after 2018 retain the old deductibility rules. Modifying an existing pre-2019 agreement can trigger the new no-deduction rule depending on how the modification is drafted.
Worked example: GS-14, 28 years service, 18-year marriage
Maria is a GS-14 Step 7 at the Department of Veterans Affairs. She is 55 years old, has 28 years of FERS service, and a high-3 salary of $145,000. She was married for 18 of those 28 years. Her TSP balance is $680,000. She and her spouse are divorcing.
FERS annuity, if the court awards 50% of marital share:
- Total FERS annuity at retirement: 1% × $145,000 × 28 = $40,600/yr
- Marital fraction: 18 ÷ 28 = 0.643
- Former spouse share: 50% × 0.643 × $40,600 = ~$13,050/yr paid by OPM to former spouse
- Maria's net annuity after division: $40,600 − $13,050 = $27,550/yr
If court also orders a full court-ordered survivor annuity (COSA) at 50%:
- Additional 10% reduction: $40,600 × 10% = $4,060/yr
- Maria's net annuity: $40,600 − $13,050 − $4,060 = $23,490/yr ($1,957/mo)
- Former spouse survivor benefit upon Maria's death: 50% × $40,600 = $20,300/yr
TSP, if the court awards 50% of marital-period balance:
- Total TSP: $680,000
- Court typically awards by specific dollar amount or percentage of account balance as of a specific date
- If the order awards 50% of account balance as of the date of divorce: former spouse receives ~$340,000 via a separate TSP account or direct rollover
- 10% early withdrawal penalty waived on RBCO-qualified distributions
FEHB:
- Former spouse must elect TCC within 60 days of divorce
- TCC cost for a BCBS Standard family plan (hypothetical): ~$850–1,100/mo depending on plan
- If the court order awards a COSA, former spouse may qualify for long-term spouse equity enrollment
Note: these numbers illustrate mechanics, not outcomes. The actual settlement depends on negotiation, state law, and each party's full financial picture. These calculations alone justify the cost of a federal benefits specialist in the divorce proceeding.
The advisor case: why this is not a standard divorce
The most expensive mistakes in federal employee divorces happen before anyone talks to a federal benefits specialist:
- QDRO drafted for TSP — rejected; TSP not divided; years pass before anyone catches it
- COSA not included in divorce decree — employee remarries; survivor annuity benefits new spouse; former spouse loses protection
- Former spouse misses 60-day TCC window — loses access to federal health coverage bridge
- COAP filed with OPM years after retirement instead of after divorce — former spouse's share not being withheld from annuity payments that already went out
- FERS supplement not addressed in settlement — terminates at 62 with no notice or recourse
A generalist family law attorney can handle the marital asset framework. But the federal-specific documents — the RBCO language for TSP, the OPM COAP for the annuity, the COSA requirements — need someone who has drafted and submitted these orders before. A fee-only financial advisor who specializes in federal employee benefits can model the financial impact of each scenario before the settlement is finalized.
