Employee vs. Employer Contributions
In most 401(k) plans, employees contribute a portion of their income, and employers may match contributions based on a defined formula. A good QDRO will distinctively divide:
- Employee elective deferrals, which are always 100% vested
- Employer contributions, often subject to a vesting schedule
Only the vested portion of employer contributions can be divided. If the divorce occurs before full vesting, the alternate payee (usually the ex-spouse) may not be entitled to the full match. Your QDRO should clearly state whether non-vested funds are excluded or whether the alternate payee will be entitled to any newly vested amounts post-divorce.
