Illegal construction confirmation and forced demolition are highly frequent dispute types in expropriation and demolition practices. A large number of houses have incomplete formalities or missing certificates due to historical construction backgrounds, policy legacy issues and special land use attributes, and are easily and arbitrarily identified as illegal buildings and forcibly demolished by administrative authorities. In practice, many buildings are legitimate historical structures, homestead self-built houses and agricultural supporting buildings rather than genuine illegal constructions. However, to reduce demolition costs and accelerate progress, expropriating authorities arbitrarily apply illegal construction penalty procedures and conduct forced demolition without legitimate investigation, public announcement, prior notification and defense procedures. Such actions violate statutory procedures and seriously infringe upon clients’ property rights and interests. Most parties cannot distinguish procedural illegalities from substantive illegal construction, lack knowledge of statutory forced demolition procedures, and miss the time limit for statement, defense, reconsideration and litigation, ultimately resulting in demolished houses and zero compensation.
