Employee Contributions vs. Employer Contributions
If the participant spouse has made direct contributions to the plan (similar to 401(k) deferrals), those typically belong solely to them unless otherwise divided. Employer contributions, however, are subject to plan vesting. Depending on the vesting schedule, part of the account may be “non-vested” and revert to the employer upon divorce.
In drafting a QDRO, it’s critical to clarify whether only the vested portion is to be divided or if future vesting rights are to be shared. Courts vary on this, so your divorce judgment or settlement matters here too.
