Employee vs. Employer Contributions
In most 401(k) plans, the account balance includes both employee salary deferrals and employer matching or profit-sharing contributions. These two sources aren’t always treated the same in a QDRO:
- Employee contributions are usually 100% vested and immediately divisible.
- Employer contributions may be subject to a vesting schedule. Unvested amounts cannot be divided unless and until they become vested.
If the participating spouse (known as the “participant”) leaves the employer before becoming fully vested, the alternate payee (the ex-spouse) may lose part of their awarded amount. This is why it’s essential to request a detailed account statement with vesting information before finalizing the QDRO.
