1. Employee and Employer Contributions
The first step is understanding what kind of contributions are in the account. Most 401(k) plans consist of:
- Employee contributions: These are the funds the participant deferred from their paycheck. They are always 100% vested and divisible in a QDRO.
- Employer contributions: May be subject to a vesting schedule. If some employer contributions aren’t vested as of the date of divorce, they aren’t part of the divisible amount under the QDRO.
To avoid disputes, make sure your QDRO clearly defines the “cutoff date” for division—typically the date of divorce or separation—and whether it includes market gains/losses from that point forward.
