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 Financial Support. Most commonly used while sponsoring an immigrant to the United States, this affidavit form simply states that the signer will be financially responsible for the incoming immigrant. The names and addresses of both parties are commonly included with the sponsoring party s signature.
Affidavit of Small Estate. Small estates generally have an easier path through the probate process. You can use this affidavit to inform the court that the estate in question actually qualifies as a "small estate", which is usually capped around $150,000. Note that residents of New Hampshire, Kentucky, and Georgia should not use this document.
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.
