Employee vs. Employer Contributions
401(k) balances are typically made up of two types of contributions:
- Employee Contributions: These are fully vested and subject to marital division based on the period of the marriage.
- Employer Contributions: These may be partially or fully unvested at the time of divorce. If not vested, they may not be subject to division unless specific future vesting terms are addressed in the QDRO.
It’s important to confirm with the plan administrator what portion of the employer contributions are vested and available for assignment to an ex-spouse.
