Bethenny Frankel's Husband Declares Divorce War

Bethenny Frankel's estranged husband has made it clear ... he's not going down without a fight in divorce court, because he's gunning for exactly the same spoils Bethenny wants from him.

TMZ has learned Jason Hoppy has filed his response to Bethenny's divorce petition, in which he's requesting PRIMARY CUSTODY of the couple's 2-year-old daughter. We broke the story, Bethenny also wants primary custody.

Jason also wants child support from Bethenny -- she wants the same from him.

Jason is asking for Bethenny to foot the bill for medical and dental insurance as well as related expenses for himself and daughter Bryn. In Bethenny's legal docs she asks that Jason pay for her medical and dental bills, as well as Bryn's.

Jason wants Bethenny to maintain life insurance on herself, making both Bryn and him beneficiaries. She wants him to maintain a life insurance policy for her benefit as well as Bryn's.

And last but not least ... Jason wants "exclusive use and occupancy of the marital residence." Surprise -- Bethenny wants that too.

Ah, one last thing. He wants her to pay for his lawyer, accountant, etc.

This one's not gonna end nicely.
