Second, it is not an illegal building. If the local government says that the demolition will not be compensated, you will not sign the demolition contract! If they don't sign, it's illegal for them to tear down the house! Whether you have a real estate license or not, as long as you can prove that the house is yours and legally built, the compensation for demolition is the same! You can appeal to the county, the city or even the province, and you can sue the court in case of forced demolition!
