401(k) Vesting Schedules and Unvested Employer Contributions
A major issue in 401(k) QDROs is how to divide employer contributions that may not be fully vested. With corporate plans like the Mtr 401(k) Plan, employer contributions are often subject to a vesting schedule—meaning the employee must work for a certain number of years to have full ownership of those funds.
If a divorce occurs during employment, it’s critical to determine:
- Which employer contributions are already vested
- Which are still unvested (and possibly subject to forfeiture)
Most QDROs only divide the vested portion unless otherwise agreed in the divorce. You’ll need documentation showing the breakdown of employee vs. employer contributions and details on the vesting schedule. This is information the plan administrator can and should provide upon request.
