Employee and Employer Contributions
Typically, both the employee and employer make contributions to a 401(k) plan. Most court orders divide total account balances, regardless of who contributed what. But here’s the catch: employer contributions may not be 100% vested. Unvested funds could be forfeited if certain service requirements haven’t been met.
That means your QDRO should specify whether the alternate payee receives a share of just the vested amounts or also includes unvested employer contributions that later vest. Plans like the Irvine Park Railroad Inc.. 401(k) Plan often include these types of schedules, especially for corporate employers.
