Employee vs. Employer Contributions
In a defined benefit plan, you generally can’t pinpoint employee and employer contributions like you can in a defined contribution plan. Since the monthly pension payout reflects both contributions, the QDRO typically assigns a percentage of the benefit based on marital service time.
You may have heard of the “coverture formula,” which is standard in these cases. It allocates a proportion of the monthly benefit to the former spouse based on how much of the participant’s service occurred during the marriage.
