Employee vs. Employer Contributions
Typically, the employee’s deferral contributions are 100% theirs and fully divisible through a QDRO. However, employer matching or profit-sharing contributions may be subject to a vesting schedule—meaning the participant only gains ownership over time. If the participant is not yet fully vested, a portion of the employer contributions may be forfeited upon separation.
Make sure your QDRO addresses which date’s balance is being divided (such as the date of separation or date of divorce), and whether the alternate payee is entitled to earned but unvested employer contributions, if and when they become vested. This can make a big difference.
