Employee vs. Employer Contributions
401(k) plans commonly contain both employee and employer contributions. Employee deferrals are always fully vested, but employer matches might be subject to a vesting schedule. That means the alternate payee (the spouse receiving a portion of the account) may not be entitled to the entire balance if the participant was not fully vested at the time of divorce.
If you’re drafting a QDRO for the Vitalsmarts 401(k) Plan, check with the plan administrator to understand the vesting schedule and use a valuation date that accurately reflects the marital portion of the plan.
