Employee vs. Employer Contributions
401(k) plans usually contain both employee-deferrals (from wages) and employer-matching contributions. Often, only a portion of the employer money is “vested,” or fully owned by the participant. When dividing benefits, only the vested amount is available for distribution to an ex-spouse. If you’re not sure how much was vested as of the date of divorce or agreed-upon division, you’ll need to get a participant statement or contact the plan administrator.
