Employee Contributions vs. Employer Contributions
The employee’s contributions to a 401(k) are always 100% vested. That means they fully belong to the account holder from day one. However, employer contributions — such as matches or profit-sharing — might be subject to a vesting schedule. If your QDRO divides the account as of a certain date, it’s important to know whether the employer contributions were vested at that time. Otherwise, the alternate payee (usually the non-employee spouse) could receive less than expected.
