1. Employee and Employer Contributions
Like many 401(k) plans, this one may include both employee deferrals and employer matching or profit-sharing contributions. But not all contributions are immediately owned by the employee. Some may be subject to a vesting schedule, especially employer contributions.
Your QDRO should clearly indicate whether the alternate payee (the non-employee spouse) will receive a share of just the vested account balance or both vested and unvested amounts at the time of division. If a portion is forfeited due to vesting, you may need provisions addressing this.
