1. Employee vs. Employer Contributions
In 401(k) plans, part of the account comes from the employee’s paycheck deferrals, and some may come from employer contributions, such as matching or profit-sharing. During divorce, only the marital portion is divided by QDRO—so if contributions were made before the marriage, those are usually considered separate property.
Also, many employers only contribute if the employee stays a certain length of time—this brings us to vesting.
