Yep do that first and find out what the access agreement says just to make sure you're in the right, then you can go after them.Will have to dig out the deeds, we bought the land 2000 and put up the corral to aid catching/ transporting cattle back to the steading . The sewage works have been there as long as I can remember .
never been a problem until last 2 years.
Was there a gate when you bought the land? Does the track part even belong to you?
