We rented our fields out to someone who supplied the rental agreement, contained things such as who he would allow on the land, liability for fences, his insurance, dates of start and finish. I amended his grazing/ haymaking to just grazing. Didn't cover the dead sheep lying on the land, or the trailer which he must have put then in which we could smell 400metres up at the house.
That didn't last long.
Next one, 6month, £20 acre with verbal agreement he would do something with the docks, thistles and rushes. Did s*d all, and left sheep on for an extra month no extra rent.
Next time I'll ask for extra money up front.
So J&J, depends how you value your land and the farmers reputation ?
