1. Employee vs. Employer Contributions
Most 401(k) plans include separate pots for employee contributions (which are always vested) and employer matches (which may be subject to vesting). It’s important to determine:
- What contributions were made during the marriage?
- Are all employer contributions fully vested?
- Should only the vested portion be divided?
Unvested employer contributions typically revert to the plan if the employee leaves the company, so they aren’t always included in the marital split unless expressly agreed upon.
