Employee Contributions vs. Employer Contributions
A 401(k) plan typically includes contributions made by the employee (from paychecks) and the employer (as matching or profit-sharing). In a divorce, both of these components can be divided—but not always equally.
If, for example, the employee’s contributions were made entirely during the marriage, then they’re usually considered marital property. But employer contributions and their vesting schedules can complicate things.
