Dividing TSP, Military Retirement, and Maryland State Pensions in Divorce

If your spouse works for the federal government, serves in the military, or is a Maryland state employee, their retirement can't be divided with a standard QDRO. Each plan type requires its own specialized court order with specific formatting rules — and the consequences of getting it wrong are worse than with private-sector plans.

Thrift Savings Plan (TSP)

The TSP — the federal government's version of a 401(k) — requires a retirement benefits court order that meets the Federal Employees' Retirement System Act requirements. The TSP will accept either a QDRO-style order or a court-approved property settlement, but the language must comply with the TSP's specific formatting requirements laid out in their booklet "Court Orders and Powers of Attorney."

Key TSP rules:

• Separate orders required. If both the TSP and a FERS/CSRS pension need dividing, you need two separate orders — the TSP won't process a combined order.
• Percentage or dollar amount. The order must specify either a fixed dollar amount or a percentage of the account balance as of a specific date.
• Loans complicate things. If the participant has an outstanding TSP loan, the order should specify whether the loan balance is included in or excluded from the amount to be divided.
• Processing timeline. The TSP Board typically processes orders within 60-90 days of receipt. The alternate payee can then transfer their share to an IRA or eligible retirement plan.

Federal CSRS and FERS Pensions

Federal employees under the Civil Service Retirement System (CSRS) or the Federal Employees Retirement System (FERS) have defined benefit pensions administered by the Office of Personnel Management (OPM). These plans are exempt from ERISA entirely, so a QDRO won't work.

Instead, you need a Court Order Acceptable for Processing (COAP). OPM has strict formatting requirements — they publish model language and will reject orders that deviate from it. The COAP must:

• Identify the employee by full name, date of birth, and Social Security number
• Specify the former spouse's entitlement as a fraction, percentage, or formula
• State whether the award is based on the employee's "gross" or "net" annuity
• Address survivor benefits (whether the former spouse receives a survivor annuity if the employee dies first)

OPM takes 4-6 months to process COAPs — significantly longer than most private plans. Submit early.

Maryland State Retirement and Pension System

Public school teachers, state police officers, correctional officers, and other state employees participate in the Maryland State Retirement and Pension System (MSRPS). This system requires a state-specific Domestic Relations Order (DRO) — not a QDRO.

The MSRPS is notoriously strict about order formatting:

• Identify the exact subsystem. The DRO must name the specific subsystem — Employees' Pension System, Teachers' Pension System, Law Enforcement Officers' Pension System (LEOPS), etc. A generic reference to "the Maryland State Retirement System" will be rejected.
• No lump-sum payouts. If the participant elects monthly benefits, the alternate payee receives their share as monthly payments. Immediate lump-sum distributions are not available.
• Payments start at retirement. The alternate payee only receives payments when the participant actually retires, withdraws accumulated contributions, or dies. If the participant is years from retirement, the alternate payee waits.

The DROP Account Trap

Certain public safety employees in LEOPS may participate in a Deferred Retirement Option Program (DROP). Under DROP, retirement-eligible members continue working while their monthly pension payments accumulate in a separate interest-bearing account. When they actually separate from service, they receive the accumulated balance as a lump sum.

If your DRO only references the participant's "basic allowance" and fails to include specific language about the DROP account, the plan administrator will exclude the DROP balance from the distribution. This can cost the alternate payee tens of thousands of dollars in marital assets. Every DRO for a LEOPS participant must explicitly address DROP.

Military Retirement

Military retirement pay is divisible under the Uniformed Services Former Spouses' Protection Act (USFSPA), but only the marital portion — meaning the overlap between the years of marriage and the years of creditable military service.

The Defense Finance and Accounting Service (DFAS) processes these orders and requires:

• A certified copy of the court order
• The service member's Social Security number and branch of service
• A specific formula or percentage for the former spouse's share

There's no requirement for a minimum length of marriage to divide the pension. The 10/10 rule (10 years of marriage overlapping with 10 years of service) only determines whether DFAS will pay the former spouse directly — below that threshold, the service member must make the payments themselves.

The Marital Share Formula

For all defined benefit pensions — state, federal, or military — Maryland courts typically use this formula to calculate the marital portion:

Marital Share = (Months of marriage during plan participation) ÷ (Total months of service credit)

The alternate payee usually receives 50% of this marital share fraction, paid as monthly benefits once the participant enters pay status.

Getting this formula wrong by even a few months can shift thousands of dollars over a retirement lifetime. The calculation should be based on documented service records, not estimates.

The Maryland After-Divorce Checklist includes a retirement division workflow that tracks each plan type — private QDRO, state DRO, federal COAP, TSP, and military — through its specific filing process, so the right order goes to the right administrator with the right language.
