Employee vs. Employer Contributions
Many 401(k) plans include both employee contributions (amounts the participant contributed directly from their paycheck) and employer matching or profit-sharing contributions. These employer contributions are often subject to a vesting schedule, which affects how much of that money is actually available for division in divorce.
If you’re the alternate payee, you’ll only be entitled to the vested portion of employer contributions as of the date defined in the QDRO—typically the date of separation or divorce. Any future vesting earned after that date typically remains with the participant.
