THERE IS AN ADJOINING PIECE OF PROPERTY BETWEEN MY NEIGHBOR AND I. MY SEPTIC TANK SITS ON THAT LOT SINCE 1970′S. IT HAS BEEN KNOWN AS COMMON GROUND. NEW OWNERS TOOK OVER IN 2005 AND ARE NOW SELLING ALL LOTS WHICH WERE NEVER FOR SALE UNTIL THE TAKE OVER. MY NEIGHBOR AND I HAVE ALWAYS AGREED TO BUY HALF OF THE ADJOINING LOT IF IT WAS EVER FOR SALE. WE HAVE NEVER HAD PROBLEMS AS NEIGHBORS AND HAVE ATTENDED PARTIES AND OTHER EVENTS TOGETHER ETC. HE HAS NOW WENT AND BOUGHT THAT LOT AND TOLD US HE ONLY WANTED UP TO THE GRASS (WHICH WE HAVE MAINTAINED SINCE WE HAVE LIVED HERE IN 1995). HE STATED HE ONLY WANTED THE DRIVEWAY. WE HAVE BOTH KEPT HALF OF THAT LOT MAINTAINED AND MY SEPTIC TANK SITS ON THAT LOT BUT CLOSER TO MY SIDE. NOW HE HAD THE ADJOINING LOT HE PURCHASED SURVEYED AND ACCORDING TO THE SURVEY LINES HE NOW OWNS AT LEAST HALF OF WHAT HAS BEEN OUR FRONT YARD AND WE HAVE BUILT AN ADDITION WITH A WRAP AROUND, COVERED PORCH WHICH NOW SITS ON HIS NEW PURCHASE OF THAT LOT.ANY HELP
