Stolen property is in the house of someone and we are in the process of getting a court order to retrieve it. Should we contact the landlord / property owner?

A friend from my girlfriend’s past offered to take her in sort of as a roommate. After we made the house livable and provided food and household needs and Thanksgiving dinner, she locked my girlfriend out and kept her things.

She has detained about a thousand dollars worth of my girlfriend’s property and the court is now involved. She thinks since she is renting the house, she can keep the things and the law can’t touch her.

I’m pretty certain the judge will rule in our favor and order the house open to us to retrieve the property we listed. I’m sure the woman will resist to the point of arrest, even with a court order.

I am trying to save time for access to the house and want to be able to retrieve my GF;s property as soon as the order is issued. I do not want to wait for additrional orders such as contacting the property owner. Should we contact the property owner ourselves and let them know what’s going on with their tenet, who is illegally detaining or stole our property?
