Lana is planning to get married in Japan and wants to know if it's possible to arrange a prenuptial agreement.

"I am about to get married to a Japanese national and would like to inquire about 'prenup' agreements in Japan," she writes. "Are they upheld by the court? If we were to write up our own, will it have to be registered with the ward office, or any other office, to be legally binding? If you have experience handling prenup agreements in foreign marriages, can you please tell me about your service fees?"

Yes, it is possible to make a legally binding prenuptial agreement in Japan, although it isn't a common practice. According to attorney Kaoru Haraguchi of Haraguchi International Law Office: "It is possible for couples to enter into a contract concerning their property rights and duties before they get married (Article 755 of the Japanese Civil Code). They can seek remedy with the court as long as this is considered to be an official contract."
