What is an Affidavit of One and the Same Person?

An Affidavit of One and the Same Person is a written document that establishes that two different names found on different documents refer to one person, the Affiant.

The Affidavit of One and the Same Person is usually used when a person knows or discovers that a document contains a name different from the one that he or she currently uses. The difference can be due to the following:

  • The erroneous spelling of the name,
  • Missing first or second name, or even an additional name, among others,
  • Marriage of the affiant which changes her name,
  • Change of name due to an official correction of records after the paternity and filiation of the affiant are proved; or acknowledged, or in case of change of name by reason of adoption.

An Affidavit of One and the Same Person is executed to prove that the different names found in two or more documents refer to one and the same person. This may be needed for the following:

  • In case the affiant wants to correct the discrepancy or mistake,
  • In case a new document or replacement will be issued bearing the correct name, and
  • To properly identify the affiant in the documents bearing different names.
