Land Act Article 18 stipulates:“Only those aliens may acquire or create rights over land in the Republic of China who are nationals of States that have diplomatic relations with the Republic of China and permit, according either to treaty or to their municipal Acts, Chinese nationals to enjoy the same rights in their respective countries.”The Act made clear the intention to take the principle of reciprocity. Base on the Article above, whether a foreign spouse shall acquire rights over land by succession in the Republic of China, in case their country do not permit Taiwanese to enjoy the same rights over land, would be a difficult issue. In the Supreme Court Judgment of 2008 Tai-Shan No. 2051, the judge tried to put forward a equitable solution to resolve the conflict between the foreign heirs (spouse)protection and the restrictions for foreigners to acquire land in Taiwan land policy. The judgment’s legal reasoning and it’s position on foreigner’s right protection are worth to study. The purpose of this article is to analyze and comment the reasoning of the judgment for our courts and academic reference on the issue of civil status of foreigners.
