Let me give you some proper... PROPER advice.
Go meet the lawyer who wrote your Deed... get a copy
Goto the land registrar and get a copy of your Deed
Goto the cops and put a complaint but DO NOT ask them to come to the land OR that you are taking any action.
Go find the BIGGEST and the most criminal thugs you can ever find and pay for ... got around 4.30 pm (when cops change duty... so even if someone calls the cops, it will take more than 1 hours for them to come)
BEAT THE FUCK out of the people living there and chase them out.... Change the locks, put a new barricade .... Distribute the arrak bottles to the thugs and spend the night there OR till the cops arrives.
when they do.. show them you own the land and if they want to contest it, ask them to sue you...
then leave the thugs at the land.. goto the cop station and put another case against the people you chased away from the land that they are trying to take over you land and take an immediate stay order from the courts on the following day.
trust me !
This is the easiest way
