Applicable Law for Mongolia Nationals
Under Japan's Act on General Rules for Application of Laws (法の適用に関する通則法, Article 36), the inheritance of a person is governed by the national law of the decedent.
Mongolia's Civil Code (2002) governs succession. Mongolia generally follows the nationality principle for personal law. Immovable property follows the law of the location of the property.
Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Chiba, Mongolia succession law may govern inheritance rights — but Japanese tax law always determines the tax obligation on Japan-situs property.
Renvoi (反致): May Apply
Mongolian private international law refers immovable property to lex rei sitae. For real estate in Japan, this results in renvoi to Japanese law.
