Employee vs. Employer Contributions
401(k) plans typically include both employee and employer contributions. Employee contributions are always 100% vested, meaning they fully belong to the participant regardless of service time. However, employer contributions may be subject to a vesting schedule.
In your QDRO, you need to clearly state whether the alternate payee is receiving a portion of just the vested funds or also unvested contributions that may vest later. Unvested employer contributions could be forfeited, which might decrease the alternate payee’s share if not properly accounted for during the division.
