Employee vs. Employer Contributions
Employee contributions to a 401(k) are 100% vested immediately—this means that amount is always subject to division. However, employer contributions may be subject to a vesting schedule. If the employee spouse hasn’t worked long enough to vest fully, the non-employee spouse may end up with less than expected. It’s important to review the plan’s Summary Plan Description (SPD) to determine vesting details before finalizing a QDRO.
