How do you file for a divorce for someone who is incarcerated and is there power of attorney?

He can file himself or hire an attorney to do it. A power of attorney does NOT permit the practice of law in a court.

Here, in short a person in that particular situation can file personally pro se or hire an attorney to do so, if you will. Consult an attorney in OH as soon as possible. Good luck!

Each state has a procedure to handle such cases. Consult with a local family law attorney for assistance.

Tell him to find a jailhouse lawyer who can help him out. Also many of the county courts have forms online to attempt to do it yourself. Be aware there are many required provisions that must be in a final judgment entry of divorce for it to be approved. The Cuyahoga County Domestic Relations Court has forms that may be useful if your county does not.
