The No. 1 Rule You Are Breaking When You Write An Affidavit

When you write an affidavit, it’s important to follow the rules. If you don’t follow the rules, your affidavit might not be accepted by the court or used in your case. This can mean a lot of wasted time and money for you and your client, so let’s look at some common mistakes that people make when writing an affidavit.

Not signing and dating it.

Not including all required information (i.e., name, address).

Using improper grammar or punctuation.

Making it too long or too short (this varies based upon the jurisdiction).

Including irrelevant information (which could cause problems if there is a challenge to authenticity).

Pay attention to factual accuracy in affidavits.
Avoid including opinions or speculation.
Follow proper structure and formatting guidelines.
Ensure affidavits are signed in front of a notary public when required.
Understand the legal implications of the information provided in affidavits.

Read All Relevant Documents

The first rule of writing an affidavit is to read all relevant documents before you start writing. This advice is so obvious and straightforward that it can be easy to overlook, but it’s essential. If you don’t have all the facts at hand before you start, then no matter how well-written your affidavit may be, there will be serious gaps in its contents.

For example: Let’s say that you are a witness who has been called upon to testify about an incident involving another party (the “defendant”). 

You know this man very well and have known him for many years; however, he has not always lived up to his promises or acted in his best interests. 

Sometimes he acts impulsively and irresponsibly without thinking things through first and then tries later on down the road when everything goes wrong again! On top of these issues with self-control and planning for consequences later on, down the road, he also suffers from a learning disability which makes it difficult for him sometimes too.

Organize Your Notes

Don’t worry if this seems like a lot to keep track of. We have a few tips that will make it easier to organize your notes, so you can refer back to them as needed.

First, use a notebook or computer file in which to write down the information you want to include in your affidavit. Second, organize your notes around the main points that you want to make about each witness and/or document. 

This will help ensure that all pertinent information is included in one place and allows for easy reference later on in the process of preparing the affidavit. 

Thirdly (and most importantly), use some sort of numbering system for each piece of evidence referenced for it to be easily cross-referenced with other documents or testimony provided by other witnesses during trial proceedings (for example: “I saw Mr. Diamantino get into his car parked outside my house when I was walking past on my way home from work last night”). 

Lastly – since this may be an issue if there are multiple people submitting affidavits – consider making an indexing system whereby each person’s testimony is summarized under their name so they can easily find things they need when reading through others’ statements later on down the line.”

Jot Down The Essential Points

This is a rule you’re probably breaking. Or at least, you’re not following it as closely as you should be.

Here’s why:

You are writing an affidavit to support your argument in court. The affidavit is your witness statement and if it’s not convincing enough for a judge to grant the injunction or other order, then all of your hard work will be for naught. And that doesn’t just mean wasted time; it could be costly to both sides involved in the case (and maybe even harmful).

So what does this mean? What exactly is said in an affidavit? It’s quite simple: list facts and evidence only! Don’t mention anything that isn’t essential to making your point clear and concisely articulated within the document itself which means all unnecessary details need to go out with the trash right now!

Arrange Your Arguments In An Outline

Knowing what you are trying to say is the most important part of any affidavit. There is an order in which all arguments should be presented, and you must know how it works before you can write your affidavit.

This Order Is Called Logical Flow, And It’s Essential If You Want Your Argument To Make Sense To A Judge

The basic idea behind logical flow is that there are two sides in every court case: yours and theirs (or “plaintiff” versus “defendant”). 

The plaintiff has the burden of proof they have to show why they deserve relief from the court; otherwise, their case will fail. The defendant doesn’t have this burden because they aren’t asking for anything from the court; rather, their job is simply not to lose or hurt their side further by making mistakes during testimony or by providing evidence that hurts them at trial.

Initiate With A Story If Possible

When you are writing an affidavit, your priority should be to tell a story that is relevant to the case. This is not as simple as it sounds. 

The story you tell must also be related to your affidavit and its facts. It must also relate to the readers of the affidavit to the judge or jury so that they can understand why these facts matter about other information presented in court or on paper.

This will help them make informed decisions about what happens next about your case.

Crafting a well-received legal memorandum is a crucial skill for any legal practitioner. Find insights and strategies in our guide on How to Write a Well-Received Legal Memorandum to improve the quality of your written legal work.

Start With The Facts

You are probably thinking, “What? Start with facts. That would be so boring! I want to start with my argument.”

The problem is that if you start with your argument, you have no facts to support it. You need to have the facts for them to support anything. So if you write an affidavit like that, then it won’t matter how good of an argument you make the judge will just toss it out because there aren’t any facts supporting your claim.

Organize The Content

The first step in organizing your affidavit is to decide what it’s going to be used for. This will determine the kind of content you need, which can be organized in any number of ways.

Topic-Based Organization: if you are writing an affidavit that details a specific event or series of events and want to present that information in chronological order, then you may want to organize your affidavit by topic (e.g., day 1, day 2…etc.).

2 Chronological Order: if there are multiple parties involved with different perspectives on the same issue (e.g., two witnesses testifying about an accident), then it might be easier for each person’s statement to follow one another chronologically so as not to confuse the reader with conflicting stories/testimony (or allow someone else who isn’t present at trial).

Explain Yourself Clearly, But Don’t Ramble

One of the biggest mistakes people make when they write an affidavit is rambling. 

They want to explain themselves clearly, but they use too many words in doing so. Sometimes this happens because they don’t know how to explain themselves clearly (they lack experience), and sometimes it’s just because they think that if there are more words on a page, then it seems like a better affidavit! But your goal should be clearly not the volume of text.

Expert legal writing involves more than just words – it’s about creating a professional tone and style. Discover the principles of effective legal writing in The Look and Sound of Expert Legal Writing to elevate your writing skills.

Use Simple Language Instead Of Jargon Or Acronyms

Jargon can lead to confusion when reading legal documents; therefore, keep your language simple and easy to understand throughout your affidavit! 

Using acronyms may seem like a good idea because you’ll save time typing out long phrases instead of single letters but consider what would happen if someone else had to read through your document after you finish writing. Would they understand what word stood for what acronym? It’s better just to spell everything out instead.

Use Affidavit Templates If You Can

The best possible way to make sure that your affidavit is error-free and has all the required elements is to use an affidavit template. These templates can be found online, in books, or even created by yourself. If you use a template, you will more easily be able to ensure that:

You have included all of the necessary information for your statement (such as who it’s for and when it happened)

You are not forgetting anything important about your situation

Your statement does not go on too long or repeat itself unnecessarily

Keep It Brief and Straight to the Point

The key to keeping your affidavit short and sweet is to keep it simple. When you write in a way that’s easy to understand, the judge will have no problem reading your affidavit and understanding all of its points. To do this, follow these tips:

When it comes to legal correspondence, mastering the art of writing demand letters is paramount. Explore our guide on How to Write a Complaint Demand Letter or Other Legal Term Letter to ensure your written communication is impactful and persuasive.

Write Shorter Paragraphs

The shorter the paragraph, the easier it will be for a judge to read through your affidavit without getting lost in a sea of words.

Avoid unnecessary details or terminology that won’t make sense without context from other parts of your story (e.g., “the defendant then said something about my car”). 

These details may seem important at first glance but distract from what matters most: proving that you did or didn’t do whatever you’re claiming happened (i.e., proving one side’s case). 

If any details like this are relevant enough for inclusion in an affidavit details about events surrounding where something happened or when it happened leave those out until later on in the document so they don’t bog down readers right away!

Think Of The Readers Of Your Affidavit Before Writing It

The first thing to keep in mind when writing an affidavit is that you are not writing a letter to a friend or colleague. You are not writing an email to your client or boss. You are not even writing a legal brief to your colleague’s lawyer.

In other words, when considering who will read and judge your affidavit, do not write as if they were any of these people:

Your friend or family member (you can use “you” instead of “I” and personalize it)

Your client (use the appropriate format for delivering it)

The judge (adopt proper language)

Be Honest and Stick to the Facts

Don’t exaggerate.

Don’t lie.

Don’t embellish.

Don’t tell stories, especially stories about how you were a hero and saved the day during that one time your car broke down in front of Best Buy or something like that. 

I strongly encourage you not to talk about your life at all and don’t make things up! Your affidavit should be an accurate representation of what happened and nothing more so don’t write anything that isn’t true! 

If you do, it will backfire on you later when the other side gets their hands on your affidavit and may try to use it against you (which could lead them straight into perjury charges). 

Not only that but if word gets out that someone lied in their affidavit then no one will trust them anymore because everyone knows liars always get caught eventually (even though this is rarely true in real life). And then if people don’t believe what they say anymore they won’t be able to do anything right either.

Make Sure You Have Proof To Back Up Your Claims

You have to make sure that you have the proof to back up your claims. A good affidavit has a record of when and where the evidence was adduced, and how it came into your possession. This can be as simple as having a log with all of the relevant dates and times that your documents were created or received.

The most important thing is to keep track of what’s going on in your life to provide accurate information for future court proceedings!

Never Lie Or Exaggerate Facts In Your Affidavit. You May Be Called To Testify

Let’s be honest: perjury is a crime. If you lie in an affidavit and later testify to the truthfulness of your statements in court, that’s perjury. And if you get caught, you can be charged with fraud or contempt of court. So don’t do it!

If someone tells you that your memory isn’t accurate, don’t exaggerate facts or makeup information just because you want your affidavit to match their version of events. If one side says something was blue and another says it was green it doesn’t mean they’re both right!

Stay Away From Unnecessary Information or Details That Are Not Necessary for the Case. These Might Confuse or Bewilder the Reader.

The most important rule you need to know about affidavits is that the writer should avoid unnecessary details and focus on the facts. The purpose of writing an affidavit is to prove that a person has been involved in a particular event or incident by giving evidence, which usually includes some sort of testimony.

If you include unnecessary information in your affidavit, it could confuse or bewilder the reader. Your goal as a writer should always be to keep it short and simple so that you can get your message across clearly without too much detail or confusion.

State Only What You Can Testify Under Oath In Court

You should write your affidavits so that they only contain information that you could prove in court if necessary. Statements that are not based on facts and knowledge are not acceptable. You can’t say things like “I know that” or “I believe”. 

You need to be sure of everything you say because if you make a statement in an affidavit, someone else might later ask you what makes up that knowledge or belief and expect an answer from you.

Your testimony must also be relevant to the case at hand otherwise, why include it? This means no repeating statements from previous cases or adding irrelevant details about yourself just because they sound nice (but don’t).


If you’re going to write an affidavit, make sure you have all the facts and remember that it’s not a place to embellish or exaggerate. You’ll want to keep things straight to the point so that the reader can understand what you’re trying to say without any confusion about it. 

If at any time during your research or writing process, you feel like something might be unclear or confusing for someone else reading through their affidavit later on down the road then don’t hesitate in asking questions from other people who have been through this process before!
