1. Employee vs. Employer Contributions
Contributions made by the employee are always 100% vested. But employer contributions (such as matching or profit-sharing) often have time-based vesting schedules. Only vested funds can be distributed under a QDRO.
In the case of the Public Library of Science 401(k) Profit Sharing and Trust, figuring out the vesting schedule is crucial. If the participant hasn’t been with the employer long, some employer contributions may not be available for division.
