medical deduction filing married filing separately domestic abuse

my husband cheated and such we are living separately.  I want to file married filing separately.  

The condo is in my name and I am making the mortgage and property tax payments as I always have.  We have no joint bank accounts.  He has refused to reimburse me for the health insurance premiums which are automatically deducted from my pension.  we are not together.  He refuses to sign paperwork to have his insurance premium payments paid by himself instead of withdrawn from my pension.  Can I claim his health insurance premiums as an itemized medical deduction?  In this case must he also itemize vs using a standard deduction?  We are not talking.  I'm pretty sure he does not have enough to itemize and deduct on his own.

 

So can I itemize his health insurance premiums which I paid for and what or how do I do that?  Any special forms?  Must I talk to him through his attorney?  Please help.  Thank you.
