We own property in the UP of Michigan that has been in our family for over 30 years. Property is landlocked on 3 sides, with a lake on the 4th side. Verbal permission from power company-some 30 yrs ago-was given to my father to travel the power line to our property. My father blazed the original road. This road starts at a State campground, travels across another piece of property and ends up at our property-following the power line only. Have had no problems until about 3 yrs ago when new owner of the property between ours and the campground started putting up gates and chains-blocking access to our land. He states that we have no right to this road since it is technically on his property. Have tried-unsuccesfully-to handle situation with the owner. Do we have any rights? And how to we prove it? Thanks!
