Employee Contributions vs. Employer Contributions
Participants often make contributions to their 401(k) account from their paycheck, known as employee contributions. Employers may also contribute, often through matching based on the employee’s deferral rate. These employer contributions are usually subject to a vesting schedule. If the participant isn’t fully vested at the time of divorce, some employer funds may not be included in the divisible balance.
Your QDRO needs to specify how employee and employer contributions will be treated and whether only vested amounts are to be divided.
