When a legal matter or a dispute arises, you may find yourself in need of an affidavit to resolve the issue. An affidavit is a sworn legal statement or testimony that is written out of court by the affiant and then signed and given officially as evidence in a court of law. Whether you are an executive seeking counsel to understand local regulations in Chicago or an individual hoping to settle an unrelated legal dispute, affidavits can play a significant role in establishing and protecting the rights of a party. In this guide, we’ll answer some of the most commonly asked questions about an affidavit to ensure you are fully informed about this type of sworn legal document.

What Is an Affidavit?

An affidavit is a written form of testimony, a sworn statement that must be witnessed by a public official. Generally, the witness is a notary public but a court official or other qualified individual may also be legally allowed to witness the affidavit. It is simply a document that has been signed and notarized by the appropriate authority, declaring that its contents are true and that it is legally binding.

An affidavit typically contains the individual’s name, address, occupation, date of swearing, submitted facts and details concerning the matter in need of settlement, and any other relevant information. All of the statements in the affidavit must be true and correct and any falsehoods in the affidavit will be punishable by perjury, if necessary.

What Is an Affidavit Used For?

Affidavits are typically used as an alternative to giving testimony in court, though they may also be used as a tool in a number of other legal matters as well. Below are examples of some of the most common uses for a sworn affidavit, as well as a brief explanation of each.

• Court proceedings – Affidavits can be used to present evidence in court, essentially taking the place of the affiant’s oral testimony. This can be useful for either the plaintiff or the defendant in a case, as the affiant does not need to be present in court to provide the information in the affidavit.

• Legal paperwork – Affidavits can also be used to certify that a certain document is legitimate, or to provide proof of identity. They are most commonly used to affirm the veracity of a will or trust instrument, to provide evidence in support of a passport application, or to serve as proof of residency or of service in the military.

• Adoption proceedings – Affidavits are often used in the adoption process, as they provide a way for attorneys and/or parties involved in the adoption to legally certify certain aspects of the procedure, such as giving consent to the adoption or reinforcing the rights of the adoptive parents.

• Landlord-tenant disputes – Affidavits can serve as proof of a tenant’s right to remain a tenant in a particular location, and can therefore be used as evidence in cases involving landlord-tenant disputes.

• Insurance claims– Affidavits are commonly used as part of the documentation supplied in insurance claims. The affidavit serves to support the claim and to provide proof that the claimant is as described on the insurance policy.

Who Can Write an Affidavit?

An affidavit is a written legal document and therefore must be written by a licensed attorney in order to be legally valid. However, if the case is one that is relatively minor in nature, it may be lawful for a non-attorney to write the affidavit. In all cases, however, the individual signing the affidavit must be willing and able to verify the veracity of the statement in the affidavit.

What is the Difference Between an Affidavit and a Declaration?

An affidavit and a declaration are two different types of sworn statements, though both serve the same purpose of providing evidence to settle a dispute or prove a case in court. The main difference between the two is that an affidavit must be signed by a third party witness and notarized, whereas a declaration is simply signed by the individual who wrote the statement. Another difference is that an affidavit must include all the necessary details of the case, including the affiant’s name, address, occupation, and other necessary information, while a declaration does not need to include this information.

When Does an Affidavit Need To Be Used?

An affidavit is needed when a legal issue arises and there is a need for a sworn statement of the facts. It can be used for a variety of civil, criminal, and administrative matters, including court proceedings, landlord-tenant disputes, insurance claims, and adoption proceedings.

How is an Affidavit Prepared?

An affidavit must be prepared by a licensed attorney. If you are in need of an affidavit, it is best to contact a legal professional in order to ensure that it is prepared properly. Your lawyer should be able to provide you with all the necessary information about how to prepare the affidavit correctly, and will also be able to make sure the affidavit is legally valid and provides evidence that will be accepted by the court.
