Dividing Employee vs. Employer Contributions
When dividing a 401(k) plan, it’s not as simple as just splitting the total account balance in half. You need to identify:
- The portion of the account that was earned during the marriage (marital vs. separate property)
- Which portions are employee contributions vs. employer contributions
- Whether any employer contributions are subject to a vesting schedule
In many plans, the employee’s contributions are 100% vested immediately. Employer contributions, on the other hand, often vest over time. If your spouse isn’t yet fully vested, the QDRO might include language that awards you a share of the vested portion only, or it could include language about future vesting if permitted under the plan terms.
