1. Employee and Employer Contributions
401(k) plans generally contain:
- Employee contributions: Always 100% vested. These can be divided via QDRO.
- Employer contributions: These may be subject to a vesting schedule. Only the vested portion can be awarded to an alternate payee.
If timing matters—such as cutting off the division at separation rather than final divorce—you’ll want to specify that clearly in the QDRO.
