Employer Contributions and Vesting
Since this is a profit-sharing 401(k) plan offered by a corporation in the general business sector, it’s highly likely that the employer makes discretionary contributions. These contributions are often subject to a vesting schedule. That means even if there appears to be a large plan balance, some of it might not be considered marital property if it’s not vested at the time of the divorce.
A properly drafted QDRO will need to include language clarifying whether the division is limited to the vested portion of the balance or includes unvested amounts (which may be forfeited if the participant leaves the company). Spouses need to be cautious assuming they’ll receive 50% of the entire account value on paper.
