Cross-Border Coordination for an Inheritance Registration: Three U.S.-Based Heirs Renouncing Japanese Real Property

Inheritance — coordinating three U.S.-based heirs so a Japanese inheritance registration could be completed.

Background

Three individuals residing in the United States were co-heirs to real property in Yokohama through their late mother. None of the three had any prior experience with Japanese legal procedures. The objective was to have them formally consent to a division agreement transferring the property to a Japan-based heir, so that the resulting registration could be completed at the Legal Affairs Bureau.

Challenge

The heirs were spread across three different U.S. states, each with distinct personal circumstances. One heir was seasonally relocating between two states, had an outdated address on her driver’s license, and lived in a gated private community where regular mail delivery — and even courier access — was not available. Japanese identity verification procedures assume postal and address conditions that simply did not exist in this case, and coordinating notarization across multiple states while meeting Japanese registration standards added further complexity.

What We Did

Acting in cooperation with the lead Japanese firm handling the registration, our office took charge of all communication and coordination with the three U.S.-based heirs. We guided them through notarization and document preparation via email, and conducted identity and intent verification calls with each heir by international phone. When the standard verification method broke down due to local postal and housing conditions, we investigated the facts through direct interviews, explained the U.S. realities to the Japanese side in terms they could act on, and coordinated through several rounds until a compliant alternative was agreed and completed. Our familiarity with U.S. address conventions, notarization practices, and postal infrastructure was what made that translation between the two systems possible.

Outcome

From initial contact with the U.S. heirs to completion of our coordination role, approximately four months. The registration was subsequently filed by the lead firm and completed.
