1. Employer Contributions and Vesting Rules
One of the most important issues in dividing a 401(k) account is how to handle employer contributions. Not all of these are immediately “owned” by the employee spouse. Many plans—including those in general business settings like this one—use a vesting schedule. That means the employee must work for the company for a certain number of years before the employer contributions become non-forfeitable.
If the participant spouse has not fully vested, the unvested portion of employer contributions cannot be divided—and may even be forfeited after termination. Make sure your QDRO only addresses the vested amount or specifies that any allocation is “subject to vesting.”
