Employee and Employer Contributions
The participant’s contributions (taken from their paycheck) are always fully vested. However, employer contributions may be subject to a vesting schedule. This means if the employee hasn’t worked long enough, they may lose some of the employer-funded portion upon leaving the company, and the non-vested portion can’t be awarded to the alternate payee.
In a QDRO, it’s important to define the timing of the division—usually as of a specific date: date of separation, date of divorce, or another agreed-upon date. This cutoff point determines what assets get split.
