Employee vs. Employer Contributions
Contributions made by the employee are always 100% vested. However, employer matching or profit-sharing contributions may be subject to a vesting schedule, especially in private-sector business entities like those in the general business industry.
In a QDRO, you can divide only the vested portion of the account. Be sure your settlement specifies whether the alternate payee is entitled to a share of the entire account or only amounts that are vested as of the divorce date or another fixed date.
