1. Employee vs. Employer Contributions
This plan likely includes both employee salary deferrals and employer matching or profit-sharing contributions. The QDRO needs to spell out which types of funds are being divided—and that may come down to vesting status. Only vested employer contributions are transferable to the alternate payee (the ex-spouse receiving a portion of the account).
Plans often have a graded vesting schedule, such as 20% per year of service. Any unvested employer contributions as of the date of divorce (or agreed valuation date) won’t be available to the alternate payee and must be excluded from the QDRO amount.
