The Majauskas Formula: How Pensions Are Divided in a New York Divorce

If you or your spouse has a pension through a New York State or municipal employer — NYSLRS, TRS, NYCERS, NYPD, FDNY — the Majauskas formula determines how much of that pension the non-employee spouse receives after divorce. Named after the 1984 Court of Appeals case Majauskas v. Majauskas, this coverture fraction is the standard method New York courts use to divide defined-benefit pensions.

How the Coverture Fraction Works

The formula isolates the portion of the pension that was earned during the marriage and divides it equally:

Marital Fraction = Months of Credited Service During the Marriage / Total Months of Credited Service at Retirement

Ex-Spouse's Share = Marital Fraction × 50% × Gross Monthly Pension Benefit

The numerator counts credited service months from the date of the wedding to the date the divorce action is commenced (when the summons is filed with the county clerk). It stops at filing, not at physical separation — a distinction that matters for couples who live apart for months or years before one spouse files.

The denominator is the total credited service at retirement, which will not be known until the employee actually retires. This means the exact dollar amount cannot be calculated until retirement, but the fractional share is locked in at divorce.

Example Calculation

A state employee married in 2005, filed for divorce in 2020, and retires in 2035 with a $5,000 monthly pension after 30 years of service.

• Months of credited service during marriage: 180 months (2005–2020)
• Total months of credited service at retirement: 360 months (2005–2035)
• Marital fraction: 180 / 360 = 0.50
• Ex-spouse's share: 0.50 × 50% × $5,000 = $1,250 per month

If the same employee had been working for 10 years before the marriage, the fraction shrinks:

• Months during marriage: 180
• Total months at retirement: 480 (1995–2035)
• Marital fraction: 180 / 480 = 0.375
• Ex-spouse's share: 0.375 × 50% × $5,000 = $937.50 per month

QDRO vs DRO: Which Order You Need

The type of retirement plan determines which court order is required:

Private employer plans (401(k), 403(b), corporate pensions) are governed by federal ERISA law and require a Qualified Domestic Relations Order (QDRO). The QDRO must be pre-approved by the plan administrator before the court signs it.

New York State and municipal pensions (NYSLRS, NYCERS, TRS) are exempt from ERISA. They require a state-court Domestic Relations Order (DRO) that complies with the specific retirement system's administrative rules. Each system — NYSLRS, NYCERS, TRS, NYPD Pension Fund, FDNY Pension Fund — has its own DRO template and submission process.

A divorce judgment that references the Majauskas formula is a legal promise, but the retirement system will not act on the judgment alone. You must draft and file the separate QDRO or DRO, get it signed by a Supreme Court judge, and submit it to the plan administrator.

Critical Details Most People Miss

Survivor benefits. If the DRO or QDRO does not explicitly name the ex-spouse as a surviving beneficiary, pension payments to the ex-spouse stop permanently when the employee dies. This can eliminate hundreds of thousands of dollars in expected retirement income. Insist on pre-retirement and post-retirement survivor benefit language.

COLAs. Cost-of-living adjustments can significantly increase pension payments over time. The DRO should specify whether the ex-spouse's share includes proportional COLA increases.

Defined contribution accounts (401(k), IRA). These are not divided using the Majauskas coverture fraction. Instead, the marital portion is the contributions and gains accrued between the wedding date and the filing date. A QDRO directs the plan to transfer that portion into the non-employee spouse's own retirement account. Transfers executed through a proper QDRO are tax-free — no income tax or early withdrawal penalty.

Social Security. Federal Social Security benefits are governed exclusively by federal law and cannot be divided by a New York divorce court. However, an ex-spouse who was married for at least 10 years may independently qualify for Social Security benefits based on the other spouse's earnings record.

Getting the Numbers Right

The Majauskas formula is mechanical, but the stakes are high. A missing survivor benefit clause, an incorrect commencement date in the numerator, or a failure to file the DRO at all can cost the non-employee spouse their entire expected pension income.
