1. Employer Contributions and Vesting
Unlike IRAs, 401(k) plans often include employer matching or profit-sharing contributions that the employee doesn’t fully own until they are vested. If your former spouse earned part of the account during your marriage but wasn’t fully vested at the time of separation or divorce, you’ll need to consider:
- What portion of employer contributions are vested vs. unvested?
- Do unvested amounts get excluded?
- Will they vest later—after divorce?
A solid QDRO addresses what happens with these amounts to avoid future disputes.
