Employee and Employer Contributions
The participant’s own contributions (made through salary deferrals) are always considered marital property if earned during the marriage. Employer contributions, however, can get tricky. Many 401(k) plans like the Arkestro 401(k) Plan involve employer matching contributions that may be subject to a vesting schedule. This means the participant must work a certain number of years before the employer’s contributions fully belong to them.
If part of the employer money isn’t vested at the time of divorce, that portion might be excluded from the division—or included with conditions. A properly crafted QDRO will distinguish between vested and unvested funds and set up how any newly vested funds should be handled if the plan allows for that type of dynamic treatment.
