When someone has a pension and gets divorced, not all of it is necessarily up for division. The portion of the pension that was earned during the marriage is marital property. The portion earned before the wedding — or after separation — is generally the employee's alone.
To figure out which is which, courts use a simple ratio called a coverture fraction. The word sounds old-fashioned (it comes from old English common law), but the math is straightforward:
For example: if someone worked at a company for 25 years and was married for 20 of them, the marital share is 80% (20 ÷ 25). If the pension pays $3,000/month, the marital portion is $2,400/month. The other $600/month — earned in the five years before the marriage — stays with the employee.
Once the marital portion is established, it gets divided between the spouses. In most states, 50/50 is the starting point — each spouse is entitled to half of the marital portion. Courts in equitable distribution states (most of the country) can deviate from that based on the full financial picture, but 50/50 is usually the baseline used in negotiations.
The legal tool used to actually transfer the pension benefit to the non-employee spouse is called a QDRO — a Qualified Domestic Relations Order. A QDRO is a court order that instructs the pension plan administrator to pay a portion of the benefit directly to the other spouse when the employee retires. For more on how this works, see What is a QDRO? A Plain English Explanation.
Maria started her teaching job in 2002. She got married in 2009. The couple separated in 2024. Her pension is projected to pay $4,200/month at retirement.
Total years worked: 2024 − 2002 = 22 years.
Years married while working: 2024 − 2009 = 15 years.
Coverture fraction: 15 ÷ 22 = 68.2%.
Marital portion: $4,200 × 68.2% = $2,864/month.
Each spouse's starting point: $1,432/month.
The remaining $1,336/month — earned in the seven years before the marriage — belongs to Maria as her separate property and is not subject to division. The $1,432/month marital share would be paid to her spouse via a QDRO when Maria retires. This is illustrative only — actual outcomes depend on your state, the plan's rules, and any other terms negotiated in the settlement.
| Factor | How it affects the marital share |
|---|---|
| Married before the job started | The entire pension is marital property — coverture fraction = 100% |
| Married after separation | No marital portion — 0% of the pension is subject to division |
| Date used for "separation" | Some states use date of separation; others use date of trial or retirement. This can meaningfully change the fraction. |
| Pension value used | Monthly benefit vs. present value (lump sum) will produce different-looking numbers — but both represent the same underlying asset. |
| State property rules | Community property states (CA, TX, etc.) may handle this differently than equitable distribution states — always verify with your attorney. |
