Employee Contributions vs. Employer Contributions
With 401(k) plans like the Barbier Security Group 401(k) Profit Sharing and Trust, there are two funding sources: what the employee contributes, and what the employer puts in. Generally, everything earned during the marriage — no matter who contributed it — is subject to division. However, employer contributions may come with a vesting schedule. This means the participant may not be entitled to keep all employer-matching contributions unless they meet certain time requirements.
In a QDRO, it’s critical to account for this. If you’re the alternate payee (the non-employee spouse), make sure the order specifies whether you’re awarded only vested amounts or whether you’ll share in future vesting.
