1. Vesting Rules and Unvested Employer Contributions
A common sticking point in 401(k) QDROs is determining which portions of the account are “vested.” Employer contributions often come with a vesting schedule. If the employee spouse isn’t fully vested at the time of the divorce, some of those funds might be forfeited later.
It’s important to examine whether:
- Employer contributions are fully or partially vested
- Unvested amounts are included in the division
- The alternate payee agreement accounts for future forfeitures
A well-drafted QDRO should specify how to handle unvested funds if they later become forfeited or vested, depending on employment outcomes after the divorce.
