Hi to everyone out there. We have lived in our house for 10 years and have a 1/2 acre paddock. We have a casual agreement with a neighbor who keeps a few Sheep on the paddock, usually it's just for a week or 2 then he moves them. It keeps down the grass for us and we don't take payment and the neighbor tops it occasionally. My neighbour is also a builder and has started getting planning on various plots of land in the hamlet. He has also kept the same sheep on my field for weeks now. My question, I maybe paranoid but, could he make claim to my paddock if he keeps his sheep in there long enough?
