A Pennsylvania Unavailable Witness Affidavit is an affidavit that is used in civil or criminal cases when a witness is considered to be unavailable to testify in court. This type of affidavit is often used when a witness is deceased, unable to attend due to illness or disability, or has moved away and cannot be located. The affidavit is signed by a witness or other person with knowledge of the facts in the case and must be notarized.

The Hearsay Affidavit is a statement of facts from a person who is not present in court, but has knowledge of the facts in the case. The Unavailable Witness Affidavit is a statement of facts from a witness who is unable to attend court due to illness or disability, or has moved away and cannot be located. The Former Testimony Affidavit is a statement of facts from a witness who has previously provided testimony in the case.
