Employee vs. Employer Contributions
401(k) accounts commonly include both employee and employer contributions. The employee’s contributions are always fully vested. However, employer contributions—such as matching or profit-sharing amounts—are often subject to a vesting schedule. This is especially relevant if the participant spouse hasn’t been with the employer long enough to vest fully.
The QDRO must clarify whether it includes just the vested portion (which is typical) or attempts to capture any unvested shares, which may be forfeited if the employee spouse leaves the company early. Being clear about this helps avoid confusion or overpromising the alternate payee (the non-employee spouse).
