Common Mistakes to Avoid When Drafting an Affidavit

The affidavit is a sworn written statement used in legal matters, such as in court cases, whereby you attest, under oath, that everything you utter is the truth. It should be signed in the presence of a notary or witness officer if it is to be used as evidence. Since an affidavit requires careful preparation due to mistakes that render it invalid, which hurts your case, here is how to draft one.

When learning about affidavits, knowing affiant meaning is important. It refers to the person who gives the affidavit, the person solemnly swearing to the facts. Common mistakes of the affiant, such as vague language or lack of details, make them less credible and cause the judges to reject them.

Using Vague Language

A key mistake is making ambiguous or general statements. Statements such as “the event happened around then” make the judges have to guess dates, places, or details.

Instead, focus on the particular facts: “On March 10, 2025, at 2 PM, at 123 Main Street, I saw the red car hit the blue sedan.” Clear details make your affidavit reliable and understandable.

Mixing Facts with Opinions or Hearsay

Affidavits should only have facts you know of and not opinions or hearsay. For instance, “He was driving recklessly” is an opinion; instead, what the court wants as proof is “The car ran through a stop sign at 60 mph”.

Also avoid hearsay, such as “My neighbor said she saw it.” Just state what you directly observed, so it remains valid.

Poor Organization and Structure

A jump in ideas or illogical flow perplexes the readers. Start with your complete name, address, and relation to the case; after that, enumerate the events chronologically.

Number paragraphs and pages. Conclude with a prayer for relief and a verification clause. This format makes it easier for judges to read your story quickly.

Inconsistent Details or Terms

For instance, calling one person “Mr. Smith” in one spot and “the driver” later creates doubt. Repeat the same name or term each time.

Verify dates, amounts, and facts for consistency. Discrepancies imply negligence or deception.

Adding Unessential or Unrelated Information

You don’t want to include additional stories that do not relate to the case; that is a waste of time and dilutes your points. If you are in a property dispute, you can skip the details about what you do every day, unless it applies to the property in question.

Emphasize only the main facts. For every sentence, ask yourself if it justifies your claim. If not, then get rid of it for a concise document.

Skipping Signatures or Notarization

An affidavit, which is not signed or not sealed by a notary, is useless in court. You have to sign in the presence of the official, who acknowledges your oath.

Include a jurat clause stating you swear the contents are true. Check local rules to see if witnesses are required.

Grammatical Errors or Legal Jargon

Typos, run-on sentences, or complex legalese make affidavits hard to read. Use active voice and simplicity: “I paid $500 on time,” not “Payment was made timely by me.”

Proofread carefully. Plain language ensures that a 14-year-old will understand it, showing your integrity and preparedness.

Verification Clause Omitted

It goes without saying that every affidavit requires a final statement such as, “I declare under penalty of perjury that the foregoing is true and correct.” Without it, the document fails as sworn evidence.

Sign and date correctly. This step confirms that you stand by every word legally.

Improper Attachment of Exhibits

Where documents, photos, or records are referenced, clearly label and attach them as “Exhibit A” with a mention in the text. All that is loose or unmarked gets ignored.

Reference exhibits precisely: “See attached photo, Exhibit B, showing the damage.”

Ignoring Local Legal Requirements

Rules vary by jurisdiction: page limits, font sizes. Failure to comply results in document rejection. Do your research or consult with an attorney first.
