Employee vs. Employer Contributions
One of the most important distinctions in dividing a 401(k) plan is the source of contributions:
- Employee contributions are always 100% vested and available for QDRO division.
- Employer contributions may be subject to a vesting schedule. If the participant isn’t fully vested in the employer portion, only the vested portion can be assigned to the alternate payee in the QDRO.
Be sure to confirm the participant’s vested balance as of the cutoff date (usually the date of separation or divorce) and account only for that amount in the QDRO.
