My STBX and were only seperted for 43 days at the end of the tax year.
My 17 year old daughter chose to live with her dad and that's fine.
Hope someone can provide some guidance before I have to spend yet even more on another lawyer,
He took all documents with him and only now informed me that he filed his taxes already, married filing seperatily and itemized (in Jan.) and claimed her as a dependant and claimed the mortage interest.
We are both on the home and on the loan. She lived with both of us.
I know I have to file married seperate and itemize, but can I also claim the interest and her if he already did? Will that flag his return? Do I also file as he did?

As it stands now without those, I will get $32 back. Our joint refund last year was 27K
The mortage was paid from a joint account. Granted all of my pay did not go into the account, but it was a joint account.
I'm at a loss as to what to do. There is no communication and we go to mediation March 3.
