David built in his backyard a garage that encroached two feet across the property line onto property owned by his neighbor, Prudence. Thereafter, David sold his property to Drake. Prudence was unaware, prior to David's sale to Drake, of the encroachment of the garage onto her property. When she thereafter learned of the encroachment, she sued David for damages for trespass. In this action, will Prudence prevail? 
No, unless David was aware of the encroachment when the garage was built.  No, because David no longer owns or possesses the garage.  Yes, because David knew where the garage was located, whether or not he knew where the property line was.  Yes, unless Drake was aware of the encroachment when he purchased the property.
