Employee vs. Employer Contributions
Participant accounts in employer-sponsored 401(k) plans generally include two types of contributions: those made by the employee (typically pre-tax or Roth) and those made by the employer (often subject to vesting requirements).
When dividing the plan, you typically only have access to what your ex is entitled to. Unvested employer contributions may not be divisible. Carefully review:
- Employee deferral amounts—these are always divisible, and usually immediately vested
- Employer matching or discretionary contributions—may be partially or fully unvested based on the participant’s years of service
If a portion is unvested on the date of division, that amount could be forfeited later. A well-drafted QDRO should clearly state who gets the benefit of any future vesting.
