Vesting Schedules and Unvested Employer Contributions
One key issue in 401(k) QDROs is dividing employer contributions that may not be fully vested. Many business entities—especially in the general business industry—offer contributions that vest over time. If your spouse’s account includes unvested employer contributions, those amounts may not be available for division.
If you’re the alternate payee, it’s important to know that your portion of the account can only include what the participant has earned and vested as of the “division date” set in your QDRO. That makes it crucial to select an accurate valuation date in your divorce agreement.
