You can't file them together, if that's what you mean, because the state court is going to have jurisdiction over your divorce and the federal bankruptcy court will have jurisdiction over the bankruptcy. You can file either or both from where you are living now (Ohio), assuming you meet the residency requirements. For example, to file for divorce in California, I think you have to have lived in the state for six months and in the county in which you file for three months, or something along those lines. So, you should first check out the residency requirements for your county court and for the bankruptcy court and then you can time them so they are filed together. I had to do something similar many years ago. My ex-husband was dragging his feet, quit his job and took off to another state to "find himself" while I raised our three small children. I had all of our creditors hounding me and was barely making enough to keep a roof over our heads and food on the table at the time. I initiated the bankruptcy first and gave him the option of helping me pay for it and joining in, so that it was a joint bankruptcy. Otherwise, the bankruptcy court would have wiped the slate clean for me and creditors would have still been able to go after him. I then filed for the divorce in my county, which was not where he was or where we'd been married. It's based on where the filing party lives. If your estranged husband is being cooperative, perhaps you can suggest that you go ahead and file everything from where you are and he can join in the bankruptcy and work with you to make sure things run smoothly. I hope this helps.
Oh, and if you haven't lived there long enough, maybe you could kind of orchestrate things from where you are and file where your husband is living. In other words, you could hire someone to do the divorce and bankruptcy, list your husband as the petitioning party, since he will meet the residency requirements, and just walk everything through and make sure it gets done.
