Employee vs. Employer Contributions
The participant’s own income contributions (elective deferrals) are always divisible. But employer contributions depend on whether they’ve vested. Many 401(k) plans, including those sponsored by business entities like The clorox company 401(k) plan, use a graded vesting schedule—meaning the longer the employee has worked there, the more of the employer contributions they “own.”
If you are the alternate payee (the non-employee spouse), and your ex hasn’t been with Clorox long enough, a portion of the account may still be unvested and therefore not subject to division through the QDRO.
