Employee vs. Employer Contributions
Within a 401(k), participants typically have both employee and employer contributions. A QDRO can award a portion of each type to a former spouse (known as the alternate payee). However, this plan may have a vesting schedule on employer contributions, which affects what’s divisible.
Only the vested portion of employer contributions can be divided through a QDRO. If the employee (the “participant”) has not worked long enough with the company to be fully vested, some employer contributions may not yet belong to them—and therefore can’t be shared.
