If your tenant is not paying rent and has fallen into arrears, you have legal rights to recover the outstanding amount, but this is generally limited to the 36 months prior to filing a rent petition. You cannot file a criminal case for non-payment of rent, but you can seek eviction. It's advisable to consult a local lawyer experienced in civil cases to file a rent petition with the local rent controller and discuss the costs involved, such as legal notices, court fees, and lawyer fees. Any additional financial support provided beyond rent may require a separate recovery suit.
