An affidavit is a legal written document that enables you to present the facts of a case to a judge. It often involves exhibits, which are pertinent documents, and letters that will strengthen your argument and help you win the case. If you are defending yourself in a court of law, you will most likely be required to present a signed affidavit to plead your case. Read the tips listed below and learn about how to write an affidavit.

  • Create a numbered list of truthful facts. An affidavit most often opens with an introduction of the signed individual, citing his age, mental capabilities and competence. The rest of the numbered items on the list speak to the legal issue in question. The items should be objective facts, not opinions held by the signed individual. The last of the numbered items should be recognition of the seriousness of perjury and an oath that all the facts represented in the affidavit are true [source: Kolber].
  • Research online affidavits There are a number of Web sites that provide examples of the expected structure and language of legally binding affidavits. Affidavits cover a wide variety of subjects, and basing yours on a similar legal case will help ensure that your affidavit holds up in court.
  • Get the affidavit legally notarized. You will have to get a notary public or officer to authorize that you are the person who signed the affidavit. Notaries charge a fee for notarizing documents, such as affidavits.
  • Seek legal advice. Before you present your affidavit to the court, it's best to review your document with a lawyer. He will be able to provide you with tips and special information that should be included in the affidavit [source: Mossop].
