I've just spoken with a surveyor who has done several jobs for us over many years. He has 40 years' experience as a surveyor (but he is not a lawyer). We need to replace a fence at an IP. For at least 25 years that this house has been in our family, the back corner fence has been truncated. The plan shows our block to be rectangular and I can only guess that long ago this corner was fenced off to allow access to a carport for the landlocked neighbour at the corner, maybe to get to what looks like where they parked their cars in a carport. It looks like this carport isn't used for vehicles now. The surveyor said that unlike Victoria, in Queensland the fact that the fence may have been truncated for years doesn't give the neighbour any claim under the adverse possession laws. He said Queensland doesn't work like Victoria in this regard. The surveyor said if we rebuild the fence on the current truncated line, we are not agreeing to give up any land, but it seems sensible to built it on the property boundary. The truncated length is 3.5m and my dodgy maths tells me that could be something like 2.5m x 2.5m corner of land in their yard that belongs to us. It isn't a big bit of land, but our block is only 453sqm so we need every bit we can get. It looks like it no longer is used for vehicles so perhaps they won't mind if we put the new fence back in the correct spot. If they do object, I want to know where we stand legally.
