Employee vs. Employer Contributions
Employee contributions are always 100% vested—they belong to the participant no matter what. But employer contributions (like profit-sharing or matching funds) may be subject to a vesting schedule.
If a portion of the employer contributions isn’t vested at the time of divorce, that amount may either be excluded from the alternate payee’s share or receive a “conditional award”—meaning the alternate payee only gets it if it vests later.
