Dividing Contributions
Generally, any contributions made to the 401(k) during the marriage are considered marital property and subject to division. That includes:
- Employee Contributions: Typically 100% vested from day one.
- Employer Contributions: May be subject to a vesting schedule, meaning the participant must work a certain number of years to keep them.
If the employer portion is not fully vested at the time of divorce, the non-employee spouse’s share may be reduced or subject to further conditions. Your QDRO should specifically address how unvested employer funds are treated—whether they’re awarded only if they eventually vest or ignored entirely.
