You may bring an action on behalf of your son as his guardian or next friend, against your father in law, sounding in negligence and seek to first make a demand on him for payment of the damages associated with the injury. If he does not respond, normally you hire an attorney, incur the expense of bringing a lawsuit and perhaps he has a homeowner's policy of insurance that may pay the claim. If the claim is less than the maximum amount you can sue for in small claims actions, you could sue in small claims court, represent your son there without an attorney and seek to obtain a judgment.
