Employee vs. Employer Contributions
It’s important to understand that this 401(k) contains both employee contributions (money the participant voluntarily defers from their pay) and employer contributions (such as a company match). In most divorces, only the portion contributed and earned during the marriage is subject to division — usually based on a specific marital time period.
However, employer contributions may be subject to a vesting schedule. If not fully vested at the time of divorce or separation, some of those amounts may be forfeited when the employee leaves the company. Always review the vesting records before finalizing your QDRO.
