Tenant car damange

[Kajal Aggarwal]

Hi,

We own a four-plex and one of the tenants guest parked their car in the garage. Due to a leak that we are not aware of until this incident, the car got some spots. The tenant is asking us to reimburse the guest for the spot removal. 

I'm wondering if we are responsible for paying the guest? We were not aware of the leak until this incident so its not an intentional or negligent maintenance of the property on our part.

TIA
