Use an Affidavit if:
1. You have been asked to make a declaration or statement of fact under oath as part of a contract or legal process.
2. You want to ask someone else to make a declaration or statement of fact under oath.
Affidavit of Name Change. If you go by a name different than your birth name but have not gotten around to officially changing it through the court, use an affidavit of name change. Typically, another person (most often your spouse or a blood relative) will sign this and swear that you use a name different from your what is on your birth certificate.
Affidavit of Birth. In the event you ca not locate your birth certificate, this affidavit can be used to verify some of the facts surrounding your birth. Typically, this affidavit form will be completed by one of your blood relatives or the attendant midwife or physician. This person will state their relationship to you, how they have knowledge of your birth circumstances, and attest to the pertinent information (such as county and date of birth).
An affidavit is a statement made under oath that some fact, or set of facts, is true to the best of knowledge of the affiant. Affidavits are usually used to provide sworn statement of facts to the Courts or any other government agencies. Affidavits are usually sworn to before a Notary Public or before any other officer that has authority to administer oath. If false testimony was given in an affidavit form, the affiant or the person who executed said affidavit, exposes himself against prosecution for the crime of perjury or giving false statement under oath.
