Is there a time limitation of 25years or reach 65 years of age before the required restitution for a Federal Court conviction could be totally paid off?

There is no specific time limitation of 25 years or age limit of 65 for restitution to be paid off from a Federal Court conviction. Restitution payment requirements are typically determined based on the court order and the individual's financial situation. The court may allow for a repayment plan that extends beyond 25 years or age 65 if necessary.
