Employee vs. Employer Contributions
In most 401(k) plans, the employee (plan participant) contributes a portion of their salary, and the employer often matches a percentage of those contributions. In a QDRO, the division typically applies only to vested funds. So, while the employee’s contributions are almost always 100% vested, employer-matched funds could be subject to a vesting schedule.
This means if the plan participant hasn’t worked long enough to be fully vested, some employer contributions may be forfeited and can’t be divided. The QDRO needs to address this up front.
