Civil Service Retirement and Divorce: Dividing FERS and CSRS Pensions

If your spouse is a federal employee or retiree, their pension isn't handled like a private-sector 401(k). Federal civilian retirement plans — the Federal Employees Retirement System (FERS) and the older Civil Service Retirement System (CSRS) — are exempt from ERISA. That means a standard QDRO won't work. Instead, you need a Court Order Acceptable for Processing, known as a COAP, and it must meet the Office of Personnel Management's specific requirements or OPM will reject it outright.

FERS vs CSRS: What You're Dividing

CSRS covers federal employees hired before January 1, 1984. It's a traditional defined-benefit pension based on years of service and the employee's highest three years of average pay ("high-3"). CSRS employees do not pay into Social Security for their federal service, so the pension is often their primary retirement income.

FERS covers employees hired after 1983 (and CSRS employees who switched). FERS has three components: a defined-benefit pension (smaller than CSRS), Social Security coverage, and the Thrift Savings Plan (TSP) — a defined-contribution plan similar to a 401(k).

In a divorce, the FERS basic pension and CSRS pension are divided through a COAP filed with OPM. The TSP portion requires a separate order — a retirement benefits court order processed by the TSP's own office, the Federal Retirement Thrift Investment Board.

What a COAP Must Include

OPM publishes detailed guidance on acceptable court order language. The COAP must:

• Identify the employee by full name and date of birth (Social Security number is helpful but not required in the court order itself — it can be included in a separate cover letter).
• Expressly divide the CSRS or FERS retirement benefits. General language dividing "all marital property" or "retirement accounts" is insufficient. The order must specifically reference the civil service retirement system.
• State the former spouse's share as a formula or fixed amount. OPM accepts a fraction of the annuity (e.g., "50% of the marital portion") or a fixed dollar amount. If using a marital-portion formula, the order must define the period of marriage that overlapped with creditable federal service.
• Specify whether the award includes or excludes COLAs. CSRS and FERS pensions include cost-of-living adjustments. If the COAP is silent, OPM applies COLAs to the former spouse's share — which may or may not be what the parties negotiated.
• Address the former spouse survivor annuity. This is critical. If the COAP doesn't mention survivor benefits, OPM defaults to no survivor annuity for the former spouse. The former spouse's payments stop permanently when the retiree dies.

The OPM Review Process

Once the court signs the order, a certified copy must be sent to OPM's Court-Ordered Benefits Section. OPM reviews the order for compliance with its regulations (5 CFR Part 838). If the order meets requirements, OPM processes the division.

Processing times are long. OPM currently takes 12 to 14 months to process court orders for active employees and somewhat less for retirees already receiving payments. During this period, the employee's annuity is not adjusted — any overpayment to the retiree is recovered retroactively once the order is processed.

If OPM rejects the order, they issue a letter explaining the deficiency. The former spouse must then go back to court, amend the order, get it re-signed by the judge, and resubmit — adding months to an already slow process.

Former Spouse Survivor Annuity

Unlike private-sector plans where the QDRO handles survivor benefits automatically if drafted correctly, federal plans require explicit attention to the former spouse survivor annuity.

Under FERS, a former spouse survivor annuity provides 50% of the employee's unreduced annuity (or a proportional share based on the court order). Under CSRS, the maximum former spouse survivor annuity is 55% of the employee's annuity.

The retiree pays for the survivor annuity through a reduction in their monthly payment — approximately 10% of the annuity amount for CSRS and about 10% of the base annuity for FERS. The court order should specify whether this cost is borne entirely by the retiree or shared.

If the court order awards the former spouse a share of the annuity but is silent on survivor benefits, the former spouse receives payments only while the retiree is alive. There is no default survivor protection for former spouses — it must be in the order.

The TSP Requires a Separate Order

The Thrift Savings Plan is the federal equivalent of a 401(k), but it's not covered by the COAP. Dividing the TSP requires a separate retirement benefits court order sent to the TSP Record Keeper. The TSP has its own model language and specific requirements, including that the order must be the most recent order — a superseding order replaces any prior one entirely.

TSP distributions to a former spouse can be rolled into an IRA or other eligible retirement plan tax-free. If taken as cash, the distribution is subject to income tax but exempt from the 10% early withdrawal penalty.

Common Mistakes with Federal Pension Division

Using QDRO language instead of COAP language. OPM does not accept QDROs. If the order references ERISA or uses QDRO terminology, OPM will reject it.

Failing to specify the division period. An order that says "50% of the annuity" without limiting it to the marital portion gives the former spouse 50% of the entire benefit — including pre-marriage service years. If the parties intended to divide only the marital portion, the order must define the marriage dates and the formula.

Forgetting the TSP. The FERS pension and the TSP are separate benefits requiring separate orders sent to separate agencies. Dividing one but forgetting the other leaves money on the table.
