1. Employer Contributions & Vesting Schedules
Many 401(k) plans feature employer matching contributions that are subject to a vesting schedule. If the employee isn’t fully vested at the time of divorce, the unvested portion isn’t divisible. It’s essential to determine what part of the balance is fully vested vs. unvested to avoid assigning something that doesn’t legally belong to the employee yet.
Some plans also include a forfeiture clause—meaning any unvested money goes back to the plan if the employee leaves employment. If that happens before the QDRO process is completed, the funds may no longer be available for division.
