Sorry I took so long in posting the answer to this. Tax time gets pretty busy for me.
The answer is yes. If both of your names appear on the 1098 provided by your lender. You will each have to state the portion of interest you paid.
If only one of your names appear on the 1098, you will need to attach additional documentation that illustrates the amount you paid.
The amount each of you claim will must equal the total amount reported on the 1098.
From IRS Pub 17:
More than one borrower. If you and at least one other person (other than your spouse if you file a joint return) were liable for and paid interest on a mortgage that was for your home, and the other person received a Form 1098 showing the interest that was paid during the year, attach a statement to your return explaining this. Show how much of the interest each of you paid, and give the name and address of the person who received the form. Deduct your share of the interest on Schedule A (Form 1040), line 11, and print “See attached” next to the line. Also, deduct your share of any qualified mortgage insurance premiums on Schedule A (Form 1040), line 13.
Similarly, if you are the payer of record on a mortgage on which there are other borrowers entitled to a deduction for the interest shown on the Form 1098 you received, deduct only your share of the interest on Schedule A (Form 1040), line 10. You should let each of the other borrowers know what his or her share is.
Any tax question I answer, I will always try to cite chapter and verse of the appropriate document(s). ANY tax advice you get should always be backed up by hard evidence. Remember, the IRS says YOU have the final responsibility to ensure you are filing a correct and accurate return.
Any one who calls themselves a tax professional should be able to point you to offical documentation regarding your question.
You should examine your relationship with preparers who are unwilling/unable to do so.
Anyone else with questions, be sure to post them in individual new treads, so they dont get overlooked.
