1. Dividing Employee vs. Employer Contributions
In many 401(k) plans, the account consists of two buckets: contributions made by the employee (participant) and those made by the employer. Each has its own treatment under plan rules.
If you are the alternate payee (usually the ex-spouse receiving a share), be aware:
- Employee contributions are typically fully vested immediately.
- Employer contributions may be subject to a vesting schedule.
Your QDRO should clearly define whether you’re receiving a portion of the total plan balance or only the marital portion accrued during your marriage. Specific allocation language helps avoid confusion when the plan administrator processes the division.
