1. Employee vs. Employer Contributions
401(k) balances usually include two main types of contributions:
- Employee contributions: These are fully vested and will be divided per the QDRO terms.
- Employer contributions: May be subject to a vesting schedule—meaning they could be partially or completely non-divisible if not yet vested at the time of divorce.
If the employed spouse hasn’t met full vesting under the plan’s rules, the alternate payee might not receive part of those employer-contributed funds. Timing matters, so knowing the employee’s years of service and the plan’s vesting timeline is essential in QDRO drafting.
