1. Employee and Employer Contribution Division
The participant’s own salary deferrals are 100% theirs to divide. But employer contributions might not be immediately vested. The plan may have a vesting schedule (commonly 3- or 5-year graduated or cliff vesting), and any unvested portion would not be available to the ex-spouse under the QDRO.
Tip: Request a “vesting statement” from the plan to determine how much of the employer contribution is actually divisible.
