Employee vs. Employer Contributions
The participant’s own contributions are straightforward: they’re usually 100% vested immediately and divisible. But employer contributions may be subject to a vesting schedule. If the employee hasn’t met the requirements (often based on years of service), some employer contributions may be unvested—and therefore not divisible in divorce.
The QDRO should clearly state how to handle these situations. For example, if only vested amounts are to be divided, the alternate payee can avoid confusion or delay.
