unknown medical bills in collection

What is the name of your state? Ohio
My husband has 2 children from a previous marriage. I recently took one of the children to the hospital for a routine exam. Upon registering I found that my husbands name was listed as the "responsible party" with his ex wifes home address. I was concerned with this and changed the mailing address to our own. Low and behold, within a week we recieved a statement from the hospital ($435) that was over 150 days late. The hospital advises that there are other med bills that have been turned into a collection agency.The ex has set up these accounts as "self pay". (the bills that are not in collection will now be resubmitted to our ins.co) Needless to say, we provide excellent health insurance benefits for our children and the ex has updated ins. cards etc, for what ever reason she has chosen not to present the ins. card. We are waiting for an itemized statement from the hospital and will gladly pay what we owe, yet are extremly concerned because our credit rating could be effected by this. I know this seems vague, I guess I'm curious if we are able to hold her accountable for knowingly causing this. Had I not changed the mailing address, we would not be aware that this was going on. Any advice?

My response:

What would you like to do? Do you envision litigation to stop her? What do your husband's court orders state about billing for medical? Do you and your husband have sufficient funds to take her to court for damaging his credit rating?

I'm not sure if anything will stop her. Futhermore, I doubt that it will be worth our hassle, time and money to persue. As for his divorce order, he is ordered to carry medical coverage for the children. He is ordered to pay 20% of medical expenses not covered by insurance. The ex is to be responsible for prescriptions. Which leads me to another question....

The divorce order does not mention vision care. Both my husband and myself carry vision care for the children and she is aware of specific optical offices that are covered. Yet she has chosen recently to take the 11 year old to an optical center that is not covered. The total for new lenses and frames was $325. My husband refused to pay anything, out of frustration that she chose to go to a provider that she knew was not covered. We are now expecting to hear from her attorney. We were torn on this one. Any ideas?

Then, you've already answered all of your questions when you said,

"I'm not sure if anything will stop her. Futhermore, I doubt that it will be worth our hassle, time and money to persue."

Have a good life.
