Employee and Employer Contribution Splits
In a typical 401(k) QDRO, contributions made by the employee and employer are subject to division. The exact terms depend on:
- The length of the marriage
- The dates of employment and plan participation
- The marital property laws in your state
It’s common to divide the marital portion—the part accumulated from the marriage start date to the separation or divorce date. If the employee started contributing before the marriage or continued after separation, a coverture fraction or detailed accounting may be required.
