Employee and Employer Contributions
401(k) plans typically include both employee salary deferrals and employer matches or profit-sharing. Only the marital portion—the amount contributed between the marriage and separation dates—is subject to division. However, be cautious: employer contributions often have a vesting schedule. An unvested employer match is not always divisible or may not be accessible as part of a QDRO until the participant becomes vested, even post-divorce.
