Unvested Employer Contributions
401(k)s usually include employer contributions (matching or profit-sharing) that are subject to a vesting schedule. If the employee spouse hasn’t been with the company long enough, some of the employer contributions may not yet belong to them—and can’t be divided.
In your QDRO, you’ll want to avoid allocating any unvested funds to the alternate payee. We usually include language to restrict division to only vested balances as of a specific date, like the date of separation or divorce.
