1. Know What Type of Contributions You’re Dealing With
401(k) plans typically have both employee and employer contributions. The employee contributions are fully vested immediately. However, employer contributions—especially matching and profit sharing—can be subject to a vesting schedule. In your QDRO, it’s important to clarify whether the alternate payee is entitled to:
- Only the vested portion at the date of divorce
- Or a coverture fraction that accounts for future vesting based on marriage length
Failure to specify this can result in disputes or denial by the plan administrator.
