1. Employee vs. Employer Contributions
401(k) plans often include both:
- Employee deferrals: Fully vested and divisible.
- Employer matching contributions: May be subject to a vesting schedule, meaning not all of these funds may be available to divide.
It’s common for QDROs to specify that the alternate payee receives a portion of only the fully vested funds as of the date of division—for example, the date of separation or divorce filing depending on state law.
