T777 work space in home expense when property under spouse

We moved into a home just over a year ago. My wife did some contracting work over the last few years. We were in the house last year and we were looking to deduct some expenses cause she worked from home.

The property title, mortgage, insurance etc is all under my name. Can my spouse still deduct from income? Or would she need to be on title, property etc. To be able to make the claim?

When we rented, we were both on the lease so it wasn't a concern then. Different story now.

Edit. Seems like only commission employees can claim insurance and property taxes, so this may be irrelevant since she didn't earn commission. Can someone confirm?

Tia.
