The Hague Convention On Private International Law ratified by the Hague Conference on Private International Law may not only be suitable. For adoption as our country's own Law of Application Concerning Foreign Civil Cases, but if applied in conjunction with Article 30 of the aforesaid Law, it would provide a valuable reference for our studies. Article 13 of the R.O.C.'s Law of Application Concerning Foreign Civil Cases, for instance, is based on the primacy of national law and immutability, while the 1978 Hague Convention prioritizes instead the respondent's 'habitual residence'. Should the current Article 13(1) of the R.O.C.'s above-mentioned Law be amended such that it is based on legal residence, the Convention ought to provide a good model for our revision efforts. However, the Convention's treament of the respondent as the connecting factor and its basing of the Surrender Clause on the spouses' will requires further rexamination. As forensuring trade security and efficiency, future reforms should treat matters of matrimonial property and matters of third party involvement in matrimonial property separately. Similarly, matters concerning a spouse's individual property should be handled in accordance with martial residence law, while thrid party concerns in matrimonial property be handled in accordance with lex rei sitae. By adopting the above, not only is spousal equality maintained and trade security ensured, it also allows for greater convenience and in conformity with actual trading norms, and settles the dispute between mutability and immutability. Although the Hague Convention offers a great deal of useful information, it is still a product of compromise, which is reflected in its mixture of continental and Anglo- American law traditions along with the vested interests of the signatory countries. Nevertheless, the Convention is a valuable resource for our purposes.
