Tasneem - I would not accept this at all. It is your property and yes you cannot just evict a "squatter" - but think about it another way - it is your property - start "renovations" and make life a little difficult for them - deactivate the gate, deactivate the garage motor if you have motors on them, go to the municipality and ask them to switch the power off, if you have palisade fence in the front, remove a few panels (its really not difficult to put them back) - Try to change the coding on the gate motor receiver while they are out, so that they can't get back in - rather let them come after you than you spend money going after them.
