Questioner

A company has settled behind our gardens, since 1988 the previous company has determined the property boundary by placing a fence behind the gardens, after years of vacancy a completely new building has been placed here and the current owner believes that the property boundary should return to directly behind the sheds and not 80 cm behind the sheds (as recorded in the land registry but designated as the property boundary by the previous company for all those years), it was also promised that 6 meter high trees would be planted so that the ugly gray hall would no longer be visible, now these trees can no longer be delivered in the short term and he wants to start asphalting so the trees can no longer be planted so they should just be placed against our sheds? We have discussed everything properly and this large company is currently changing everything according to its own insight. Even on signed documents it is now said that we have misunderstood this, My question is, do we have to swallow all this?

Lawyer

If you have actually taken possession of the strip of approximately 80 cm behind your shed since 1988 (i.e. as if you were the owner / have used the strip without the permission of the actual owner), then you can take the position that you have become the owner of the strip by prescription (20 years or more of possession not in good faith) and you can legally oppose the reduction of the actual boundary in accordance with the cadastral boundary. Unless otherwise provided in a local regulation, trees may not be planted within a 2-metre wide strip along the property boundary.
