Employee and Employer Contributions
Most 401(k) plans have two sources of money: employee contributions and employer matching contributions. A QDRO can divide the entire account—including both sources. However, employer contributions may be subject to a vesting schedule. That means not all of those funds are guaranteed unless the employee has met specific service requirements with the company.
If you’re the alternate payee, make sure the QDRO only includes vested portions at the time of division, unless both parties agree to include future vesting. If you’re the employee-participant, be aware of this clause before signing off on the language.
