1. Employee vs. Employer Contributions
Most employees contribute a portion of their paycheck to their 401(k), but employers often add matching or discretionary contributions. Here’s where it gets tricky: employer contributions usually come with a vesting schedule. If the employee–participant isn’t fully vested at the time of divorce, the alternate payee could end up with less than expected.
QDROs should clarify whether the division includes just the vested balance or includes unvested amounts that may become vested later. If your divorce settlement intends to include future vesting, the language must reflect that clearly.
