Employee vs. Employer Contributions
In most 401(k) plans, the participant contributes part of their income (pre-tax or Roth) into the plan. The employer may also contribute, either through true-up matching or profit-sharing formulas. In divorce cases, it’s common to split the marital portion of the total balance, regardless of contribution source, but watch out for employer contributions that aren’t fully vested. Unvested portions are not guaranteed and can be lost if the employee leaves early.
