My property line has been the same for over 30 years. This line is fenced. Now my neighbor says that the line is wrong and has decided to use what he considers his land. When he bought the ranch this fence was in place. I am located in Shepherd Montana. Shouldn't this land, under adverse possession, now belong to me. My parents bought the property in 1970 and I bought it from the estate when my Father passes away in 2005.
