Divorce to be filed in Ohio: Question follows description

While living in Arizona, my wife and I purchased a van in both of our names. Finance documents and Title were listed myself "AND" wife. We moved to Ohio, and choose to seperate. She wanted to use the van to transport our two kids, and let me use a car I purchased and paid in full in Ohio in my name. We both agreed to continue paying the loan on the van jointly, in order to provide safe/reliable transportation for the children.

A few months after we seperated, she let the finance company repo the van, as she could no longer afford the payments. I was making payments directly to her up until this time in order to keep the van ( my mistake, should have paid the finance company directly). I could not afford the entire loan on my salary, we agreed jointly on the repo.

Shortly after, the finance company hired a law firm in Ohio. We went to court, and they were granted judgement. They then successfully went to court to get garnishment order on my salary. The law firm stated that they did not pursue the wife at this time, as she had little income and had residential custody of the children.

My wife and I are trying to come to an agreement on the dissolution, but the van is the roadblock. She does not want to add the van to the dissolution. I tried to explain that since this was a marital asset/debt, it should be properly listed in the paperwork. Everytime I try to bring up adding the van to the paperwork, she says that I am only thinking of myself and the money.

My question:
How should this debt be technically listed in divorce decree? It is a marriage debt in both of our names. We have no other debt or assets.
Or, should I leave it out of the decree so that I can get the divorce finalized? I am paying on the debt anyways, divorced or not. She has no intention of ever repaying me or the finance company for the van.

Thank you for your support and knowledge,
