Employee vs. Employer Contributions
Most 401(k) accounts include both employee deferrals and employer matching or profit-sharing contributions. In divorce, both types are typically subject to division if they were earned during the marriage. However, it’s important to separately list the contributions in the QDRO, because the employer portion may be subject to vesting requirements.
If a participant is not fully vested in employer contributions, only the vested balance as of the division date is legally divisible via QDRO. Anything unvested is usually forfeited if the employee leaves the company before vesting is complete.
