A state court has the right to divide a federal military pension because the federal government passed a law allowing states to do so. That law is called "The Uniformed Services Former Spouses Protection Act (USFSPA). The USFSPA set specific parameters on what the state courts can actually do. The Act creates a coverture fraction to determine the spousal share to the retirement. The spousal share is limited to the disposable retirement pay. The Court is limited to awarding no more than 50% of the members disposable retired pay (gross retired pay less authorized deductions).
