Home business expense deduction - wife owns house

Married Filing Jointly.  My wife bought our house in her name and is the only name on the deed and mortgage, though we both contribute to the costs equally (mortgage, taxes, repairs, etc).  I use the basement to run my business,  the entire basement is used exclusively for my business and it is the primary and only location.

 

Can I deduct any of the home expenses (based on sqft % etc) - ie. mortgage, repairs, utilities on my business?
