Employee vs. Employer Contributions
Both spouses must understand what’s being divided. The participant in this 401(k) may have only partially vested employer contributions. While employee contributions are always 100% vested, company matches typically follow a vesting schedule. The alternate payee is only entitled to what’s vested at the time of the divorce or the QDRO valuation date.
If your divorce order tries to divide unvested benefits, the QDRO will be rejected or may result in less than expected payouts. Make sure this is clear in the order and verified through the participant’s benefit statements and/or plan documents.
