I had this same problem with a trailer and lotI used to own. I owned it for 7 years and recieved it from my grandfather. The driveway went through the corner of the neighboring lot, which originally was owned by my father. I had some trouble with a SOB neighbor later that fenced off the driveway!!!! I went to a lawyer, and in VA if the road has been in use for at least 20 years (it was in existence for 31years)you have legal rights to passage, except in the case of relatives. This was the case, so I did not have a leg to stand on! Check to see if there is a time limitation in AL. Good Luck!
