How to do an oath for an affidavit

Updated March 21, 2017

When a person wants to make a sworn statement to a court of law, that person may submit an affidavit to the court. Affidavits can be drawn up by attorneys or set out in established forms. Police officers routinely present affidavits to judges in efforts to obtain search warrants. Lawyers might obtain affidavits from clients or witnesses to move the court to do something. Whatever the reason an affidavit is being used, the affiant must swear under oath that he or she has made only truthful statements in the affidavit.

Appear before a notarising officer with your affidavit in hand. The oath needs to be made in an official setting with the U.S. flag on display.

Sign the affidavit in the presence of the notarising officer.

Stand and raise your right hand to swear that everything written in the affidavit is true.

Answer in the affirmative when the notarising officer asks: "Do you solemnly swear that the statements set forth in this paper, which you have here signed before me, are true, so help you God?"

Have the notarising officer sign and place his or her seal on the affidavit.


You make the oath under penalty of perjury.


If you commit perjury, you have committed a criminal offence and can be prosecuted.
