is he registered as a sex offender?

i would go above local authorities, but first consult a some kind of legal defense organization in your state-outside of your town and ask for advise.

you can also seek out advice from a national hotline that deals with victims of sex abuse...they might have some advice.

good luck.

Have you tried the district attorney or the state attorney, they are both outside of your town. You can even try victim rights advocacy or state human resources office. You might have to file a report of abuse or something not sure what it falls under. But don't give on them they need you, Please thats the most important thing never give. keep banging and kicking down doors. Your girls will know you keep fighting and thats important for when they become women and have their own families. Good Luck

I agree, keep fighting, but equip your children. Talk to them about it being wrong if ANYONE touches them against their will. Get a cheap cell phone and make sure one of them can reach you when they are with him. Tell them, if your father or a relative or teacher or friend touches them and they don't like it, they need to tell you or call you instantly and you will help them. Keep telling them this, make them repeat it back to you. Tell them that NO ONE has the right to do this, but, they must tell you, even if they are told not to, so that you can help them. Keep reinforcing this and I tell my kids, they are not tattling and anyone who tells them to keep a secret from me, that person is trying to hurt them. You may not be able to stop their father, but, equip the children so they know they are not alone and they can say NO.

Keep fighting, you can go to Family Court without an attorney. Try to gather as much evidence as you can and make as much noise with the authorities as you can.

I have been let down by the system, so, it may do nothing for you. But, empower your kids & equip them. I was so relieved when my children were old enough to talk, but, with abuse, sometimes they won't tell. Keep talking about the subject, so they feel comfortable talking to you about it.
