My mom & biological father have been seperated for 29 years after 7 years of marriage. My bio has commited bigamy because I know he has been married @ least 3 times after they were seperated. I'm trying to find out for my mom how to divorce him since he doesn't want to sign divorce papers? Is there a way she can do it without him signing the papers? They live in seperate states as well. She's in OK & he's in CA. Thank you for any help
