The Condominium Act, B.E. 2522 (1979)/amendments 2, 3 and 4, allowed a Foreign National to legally own a unit within a condominium. A total of 49% of a condominium building may be allocated under this act. This may even be increased in certain areas such as Bangkok and Pattaya (as defined by the local land offices). In 2008, an amendment (No. 4) was made to the Condominium Act that made Property Developers responsible for accurately marketing their product and also required them to be responsible for taxes, maintenance fees and charges for any un-sold units in the building. The amendment also included various other regulations that were intended to protect the interests of property owners within a condominium.
