Employee vs. Employer Contributions
Employee contributions are typically fully vested immediately, but employer contributions may be subject to a vesting schedule. That means if the employee spouse hasn’t worked long enough, some of the employer contributions may not be “owned” by the participant yet—and may not be transferable to the ex-spouse through a QDRO.
You’ll want to include language that addresses only “vested” employer contributions, or you could end up dividing amounts that don’t actually exist.
