Employee and Employer Contributions
In most QDROs for 401(k) plans, employee contributions are fully vested and easily divided. However, employer contributions may be subject to a vesting schedule. That means if the plan participant hasn’t worked long enough to meet the vesting requirements, some or all of the employer contributions may not be eligible for division.
Your QDRO must explicitly state whether the alternate payee receives a share of all accounts or just the vested portion, and how forfeited amounts will be handled.
