Employee and Employer Contributions
One of the first things to look at is what portion of the account is made up of the employee’s own contributions versus the employer’s. The employee’s contributions are always fully vested. However, employer contributions might be subject to a vesting schedule—something spouses often overlook.
If some of the employer contributions are unvested at the time of divorce, the former spouse (alternate payee) generally isn’t entitled to those funds. That makes timing a key factor. Be sure your QDRO uses a clear valuation date—typically the date of separation, divorce filing, or another agreed-upon date—to fairly split funds that have already vested.
