Employee vs. Employer Contributions
In most 401(k) plans, contributions come from both the employee and the employer. Only the participant’s contributions are always fully vested. Employer contributions, on the other hand, might only vest over time. A QDRO must identify whether it applies to all contributions or only vested balances. It’s common for a spouse to be awarded a percentage of the vested balance as of a certain date—such as the date of separation or divorce filing.
