1. Dividing Employee and Employer Contributions
401(k) balances often include both the employee’s contributions and additional contributions made by the employer. Some employer contributions are subject to a vesting schedule. In divorce, only the vested portion can be divided through a QDRO. That means:
- If the employee isn’t fully vested, only the vested part at the time of divorce will transfer.
- The QDRO should clearly distinguish between vested and unvested funds as of the division date (often the date of dissolution or separation).
Always request a breakdown of contributions and the vesting schedule before drafting the QDRO.
