Employee vs. Employer Contributions
The Mechanical Partners, Inc.. 401(k) Plan likely includes both employee contributions (from wages) and employer contributions (matching or profit-sharing). One common issue in QDROs is dividing funds that haven’t fully vested. If the spouse participating in the plan is not 100% vested in employer contributions, the non-employee spouse may only receive the portion that’s vested as of the date used in the court order (often the date of separation or divorce).
It’s critical to identify exactly what portion of the account is vested and include language in the QDRO that either limits the alternate payee’s rights to the vested amount or anticipates future vesting if appropriate under the decree.
