Employee and Employer Contributions
Many 401(k)-style plans like the Dutchess Day School 403(b) Plan include both employee deferrals and employer matching contributions. In divorce, you can choose to divide just the participant’s contributions or also include employer matches.
Watch out for vesting. Portions of the employer contributions may be unvested at the time of divorce. That means they may not legally be part of what can be divided—unless the vesting has already occurred by the time of QDRO processing.
