Employee vs. Employer Contributions
The participant’s own contributions are fully theirs and usually 100% vested. But employer contributions vary depending on the vesting schedule. In most cases, the alternate payee may only receive the marital portion of vested employer contributions.
If the participant is not fully vested at the time of divorce, the unvested amount should not be included in the alternate payee’s share unless otherwise negotiated in the divorce settlement. Be clear about this in the QDRO to avoid delays or denials.
