What is a One And The Same Affidavit?

The One And The Same Affidavit is a crucial legal instrument in Irish law used when an individual needs to formally establish that they are known by two or more different names. This situation commonly arises due to marriage, divorce, professional use of different names, or variations in how names appear on official documents. The affidavit must be sworn or affirmed before an authorized official such as a Commissioner for Oaths or Practicing Solicitor in Ireland. It typically includes comprehensive personal details, explanations for the name variations, and supporting documentation as evidence. This document is particularly important for property transactions, banking procedures, immigration matters, and other official purposes where the legal identity of an individual needs to be definitively established across different name variations.

About the One And The Same Affidavit

A One And The Same Affidavit is a sworn legal document that allows you to formally establish that you are the same person despite being known by different names. In Ireland, this document is governed by the Statutory Declarations Act 1938 and is essential when you need to prove your identity across various name variations for official or legal purposes.

When do you need this document?

You'll need a One And The Same Affidavit when dealing with official institutions that require certainty about your identity. This commonly occurs after marriage when your surname has changed, during property transactions where documents may show different name variations, or when opening bank accounts with institutions that have records under a previous name. The document is also crucial for immigration purposes, pension claims, or inheritance matters where historical records may reflect different versions of your name. Professional situations where you're known by a different name than your legal name also require this affidavit for formal documentation.

Key legal considerations

The affidavit must include comprehensive personal details and a clear explanation of how and why different names have been used throughout your life. You must provide truthful information as making false statements in an affidavit constitutes perjury, which carries serious legal consequences including potential imprisonment. The document requires supporting evidence such as birth certificates, marriage certificates, passports, or other official documents that demonstrate the name variations. All previous names must be disclosed, including maiden names, professional names, or any informal variations you've used. The affidavit creates a permanent legal record, so accuracy and completeness are essential.

Legal requirements in Ireland

Under Irish law, your One And The Same Affidavit must be sworn or affirmed before an authorized official as specified in the Statutory Declarations Act 1938 and Civil Law (Miscellaneous Provisions) Act 2008. Acceptable witnesses include Commissioners for Oaths, Practicing Solicitors, Notary Publics, or Peace Commissioners. The Rules of the Superior Courts (Affidavits) 2009 establish formal requirements for court-related affidavits, including specific formatting and content standards. The document must clearly identify the court jurisdiction if being filed with legal proceedings. For property-related matters, the Registration of Deeds and Title Act 2006 may require additional specificity about name usage in property transactions. The witness must verify your identity and ensure you understand the legal significance of the sworn statement before administering the oath.
