1. Vesting and Forfeiture Rules
401(k) accounts often contain both employee and employer contributions. While employee contributions are always 100% vested, employer contributions might be subject to a vesting schedule. If the participant hasn’t worked at the company long enough, some of those employer contributions may not be available to divide—and could be forfeited.
Your QDRO should clearly state whether the alternate payee’s award includes only vested balances or whether it will increase if additional amounts become vested later. Failing to clarify this can lead to contested distributions or delays.
