Employer and Employee Contributions
One of the first things we look at in 401(k) divisions is the source of the funds. In the C.i.i. 401(k) Plan, there are likely contributions made both by the employee (deferrals from their paycheck) and by the employer (matching or profit-sharing contributions).
When dividing the plan, it’s important to specify whether the order will split only employee contributions, or both employer and employee balances. If employer contributions are subject to a vesting schedule, unvested amounts may not be available to the non-employee spouse.
