Contents of an Affidavit

1. Court Heading: In the case of Nigeria, Section 117(1) of the Evidence act 2011 states that: Every affidavit taken in a cause or matter shall (a) be headed in the court and in the cause of the matter.

This section is to the effect that since an affidavit is a sworn testimony of facts deposed by a person especially in support of a matter or cause before the court, such affidavit must be headed in the appropriate court which the affidavit is sought to be filed. The heading must include the name of the Court, it’s jurisdiction and judicial division.

An example of a court heading is:


2. Suit number: A suit number is the number allotted to the case before the court. Hence, it is a requirement in an affidavit which is used for a judicial proceeding. The suit number is usually written on the right corner of an affidavit just below the court heading. 

2. Names of parties: The inclusion of the names of parties is specifically for affidavits used in a judicial proceeding. The names of parties are not required in other forms of affidavit.

3. Title: The title is the subject matter of the affidavit. For example, Affidavit in support of a motion on notice, Affidavit in support of an application, Affidavit of identity, et cetera.

4. Introductory statement: An affidavit always begins with an introductory statement which must state the following: Name of the deponent, gender, citizenship, occupation, and address.

Section 117(1)(b) of the Evidence Act of Nigeria provides that: Every affidavit taken in cause or matter shall state the full name, trade or profession, residence, and nationality of the deponent. This is also the case in some other common law courts like the United States, India, Bangladesh, Ghana, South Africa etc.

An example of an introductory statement is: “I, Anayo Tochukwu, Male, Nigerian citizen, Lawyer of No 41 NBB estate do make oath and state as follows:” 

5. Statement of fact: This is a chronological statement of facts which are relevant to a case, application or the facts in issue. This statement of facts must include only facts which the deponent is conversant with, and the deponent must state these facts without argument. Section 115(1) of the Evidence Act states that: Every affidavit used by the court shall contain only a statement of facts and circumstances to which the witness deposes, either of his own knowledge or from information which he believes to be true.

6. Signature of the deponent: Also, in Nigeria, the Evidence Act provides that “An affidavit when sworn shall be signed by the deponent or if he cannot write or is blind, marked by him personally with his marks in the presence of the person before whom it is taken.”

This section therefore makes it mandatory for the deponent of an affidavit to affix his signature, failure to do so renders the affidavit useless and worthless in the eyes of law.

7. Registry: The registry where the affidavit is sworn is usually written at the bottom left corner of the affidavit, just below the signature. The registry is like:


After the mark of the registry where the affidavit was sworn, the Date of the affidavit, the stamp and signature of the commissioner of oaths or other required notary follows.
