Employee vs. Employer Contributions
The QDRO must clarify which parts of the 401(k) are being divided. Employee contributions are generally always available for division. However, employer contributions may be subject to a vesting schedule, meaning your ex may not be entitled to the full employer-funded portion.
When drafting the QDRO, we often include language that specifies the alternate payee receives a percentage of only the vested portion, or we set a clear valuation date before the vesting schedule is finalized.
