Divorced Oct 2017. Both still legally own the house, he has always paid for it, & he still lives there. How do I file my taxes?

[DianeW · Accepted solution]

The deductions for the house can be divided any way you choose if the money used to pay the expenses was from a joint bank account and it was your main home during the time mortgage interest payments were made.  If all the expenses were paid from your ex-spouse's account then only he can deduct the expenses.

Since you were divorced before December 31st, you can use the standard deduction even if your ex-spouse itemizes deductions.
