Why You Need a Certified Translation of the US Single Affidavit and US Joint Affidavit for Marrying in Japan

If you’re a US citizen planning to marry a Japanese national or another US citizen in Japan, you’ll need specific legal documents to prove your eligibility to marry. Two crucial documents in this process are the US Single Affidavit for Single Status and the US Joint Affidavit for Marriage. A certified translation of these affidavits is often required to meet Japanese legal requirements and ensure a smooth marriage registration process.

Explanation:
Here’s why you need a certified translation of these affidavits:

  1. US Single Affidavit for Single Status to Marry a Japanese Spouse:
    This document is required to prove that you are legally single and eligible to marry a Japanese national. Japanese city offices often request a certified translation of this affidavit to confirm that the information provided aligns with their regulations. Without a proper translation, your application for marriage could be delayed or rejected.
  2. US Joint Affidavit for Two US Citizens to Marry in Japan:
    If you and your partner are both US citizens wishing to marry in Japan, the US Joint Affidavit serves as a declaration of your mutual intent to marry and your legal eligibility. The Japanese authorities require a translated version to process your marriage application correctly, ensuring that all legal terms and conditions are understood.

Why Do You Need These Translations?

  • Marriage Registration: Both affidavits are crucial for registering your marriage in Japan. A certified translation ensures that the Japanese officials fully understand your legal standing and intentions.
  • Compliance with Japanese Law: Having a translated affidavit demonstrates your compliance with Japanese legal requirements, avoiding any misunderstandings or legal complications.
  • Facilitating the Marriage Process: A certified translation can streamline the marriage process by reducing the risk of delays or refusals due to language barriers.
