there is a 7ft wide easement alongside our common driveway. i have put some rocks on the easement, along the concrete driveway, to stop rain-driven mud from covering the drive. we are 1 of 8 neighbors, we all own the easement, and we are the only homeowners currently living in this 8parcel tract. 1 landowner has asked me to remove the rocks. he claims "encroachment" and says it will be harder to sell his land as this will "cloud" his title?? PLEASE advise.
