Employer Contributions and Vesting Schedules
It’s important to know that not all funds in a 401(k) account are automatically fully owned by the employee. While employee contributions are immediately vested, employer contributions often vest over time. If your spouse is not yet fully vested, and the employer contributions haven’t been fully earned, the amount you may be entitled to could be less than the account balance might suggest.
Your QDRO should clearly spell out whether it includes only vested funds as of the date of divorce or the order will track future vesting of any employer money. This is something many people overlook without experienced legal guidance.
