Employee vs. Employer Contributions
Employer and employee contributions are handled differently when a QDRO is involved. Employee contributions (including any voluntary, pretax, or Roth contributions) are straightforward. These are considered fully vested and can be divided based on the marital coverture fraction or a fixed percentage.
However, employer contributions often come with a vesting schedule. If a portion of the employer contributions has not vested as of the date of separation or divorce, that unvested balance can’t be awarded to the alternate payee unless and until it vests. This can cause confusion down the line if not addressed clearly in the QDRO.
