Former Spouse Rights During Disability, Phased, and Deferred Retirement

Most COAPs are drafted with a standard retirement in mind — the employee works until eligibility, separates from service, and starts drawing their full annuity. But federal employees also retire through disability, phased retirement, and deferred annuity pathways, each of which changes the timing, amount, or structure of the pension. If your ex-spouse takes one of these routes, your court-ordered share may look different than you expected.

Disability Retirement

A FERS disability retirement triggers when an employee becomes unable to perform their job due to a medical condition, with at least 18 months of creditable civilian service. The annuity computation differs significantly from a standard retirement:

During the first 12 months: The disability annuity equals 60% of the high-three average salary, minus 100% of any Social Security disability benefit for months the employee is entitled to it. The employee receives the earned annuity if it is larger than this amount.

After the first 12 months: The annuity drops to 40% of the high-three average salary, minus 60% of any Social Security disability benefit for months the employee is entitled to it. The employee receives the earned annuity if it is larger than this amount.

At age 62: OPM recomputes the annuity using the standard FERS formula (1% or 1.1% per year of service × high-three salary), crediting the years on disability retirement as if the employee had continued working.

Your COAP's formula interacts with this shifting computation. If your order awards a percentage of "the employee's annuity," OPM applies your percentage to whatever the disability annuity amount is at each stage. During the first year, when the annuity is highest (60% of salary minus the SS offset), your share is larger. After the first year, when it drops to the 40% formula, your share drops too. At age 62, the recomputation usually increases the annuity, and your share adjusts upward.

At age 62, OPM's recomputation credits time on disability annuity rolls as service and increases the high-three used in the formula by FERS COLAs paid during disability. The effect on your marital fraction depends on the formula stated in your COAP.

Phased Retirement

Phased retirement allows eligible employees to work part-time while drawing a partial annuity. The employee reduces their schedule to half-time, and OPM pays a "phased retirement annuity" equal to the annuity computed at full retirement, prorated by the reduction in working time (typically 50%).

For former spouses, the key question is whether your COAP entitles you to a share during the phased period. OPM treats the phased retirement annuity as a partial employee annuity subject to court-ordered division. If your COAP awards you a percentage of the employee's annuity, OPM applies your percentage to the phased annuity amount.

However, phased retirement has a significant feature: when the employee fully retires, OPM recomputes the annuity using the combined pre-phased and phased-period service. The full-retirement annuity is typically larger than the phased annuity. Your share adjusts to the new, higher computation.

The practical impact: during the phased period, your monthly payment is smaller than it would be under a full retirement. If your ex-spouse enters phased retirement at 60 and doesn't fully retire until 65, you receive a reduced share for five years.

Deferred Retirement

A deferred annuity applies when an employee separates from federal service before meeting retirement eligibility but after completing at least 5 years of creditable civilian service (FERS) or certain other thresholds. The employee leaves their contributions in the retirement fund and becomes eligible for an annuity at age 62 (FERS) or age 60-62 (CSRS, depending on years of service).

The deferred annuity is computed using the high-three average salary at the time of separation, not at the time payments begin. If the employee separated at age 45 earning $85,000, the annuity is based on that salary even though payments don't start until age 62 — seventeen years of potential salary growth are excluded from the calculation.

For former spouses, this means:

• The annuity will be smaller than if the employee had continued working until retirement age, because the high-three salary is frozen at the separation date.
• You must track the employee's eligibility date. OPM does not notify former spouses when a separated employee becomes eligible for their deferred annuity. If the employee doesn't apply, payments don't start, and neither does your share. File your COAP with OPM now so it's on record when the employee eventually claims.
• The employee might take a refund instead. Before the deferred annuity starts, the separated employee can request a lump-sum refund of their retirement contributions, which extinguishes all future annuity rights — including your share. If your COAP includes refund-blocking language under 5 CFR § 838.431, OPM will deny the refund application. If it doesn't, you're unprotected.

What Your COAP Should Say

Ask your attorney to confirm that the order's terms can be applied to each annuity type relevant to your former spouse. OPM needs a determinable share based on the order, and the calculation can differ for disability, phased, and deferred retirement.

If your existing COAP references only "retirement annuity" without specifying disability, phased, or deferred scenarios, do not assume that generic wording resolves which annuity or calculation applies. The order must state a share and formula OPM can determine under 5 CFR Part 838.

The Former Spouse Federal Benefits Guide includes a COAP audit checklist that flags whether your existing order covers disability, phased, and deferred retirement scenarios, and provides model amendment language for orders that don't.
