What Is an Affidavit? A Clear Guide for UK Businesses and Entrepreneurs

There’s every chance you’ve come across the word “affidavit” in legal documents or heard about it in a business context - and wondered what it actually means, when you might need one, or how to prepare one that holds up in the UK. The good news? Affidavits don’t need to be intimidating or shrouded in mystery. Understanding what an affidavit is, how it’s used in UK law, and when your business might require one can save you hassle, delays, and even potential legal trouble down the line.

In this guide, we’ll explain exactly what an affidavit is, why businesses and entrepreneurs might be asked for one, and walk you through the process step-by-step. Whether you’re facing a dispute, making a statutory declaration, or updating company records, keep reading for a clear breakdown that empowers you to tackle affidavits with confidence.

What Is an Affidavit?

Let’s start with the basics: an affidavit is a written statement of facts that the person making it swears or affirms to be true. It’s used as evidence in legal proceedings, and carries serious weight - signing an affidavit is akin to telling the truth under oath in a courtroom.

Here’s the official breakdown of the affidavit meaning in law:

• An affidavit is a written document setting out facts or statements relevant to a legal process.
• It must be sworn or affirmed in the presence of someone authorised, such as a solicitor or notary public.
• The person making it (the “deponent”) confirms that what they’ve written is true to the best of their knowledge and belief.
• Affidavits can be used in courts, tribunals, administrative procedures, or business transactions when facts need to be formally confirmed.

In short, think of an affidavit as a sworn written statement of truth - one that can have significant legal consequences if it turns out you’ve lied or made a reckless statement.

Tip: If you see the terms “sworn affidavit,” “affidavit statement,” or “affidavit of support,” these are simply specific types of affidavits used for particular legal circumstances.

When Would a Business or Entrepreneur Need an Affidavit?

Affidavits are surprisingly common in the business world. You may be asked for an affidavit in situations such as:

• Dispute Resolution: Providing your side of the story during litigation or a commercial dispute.
• Confirming Director or Shareholder Changes: Swearing facts about company ownership or roles for Companies House or regulatory filings.
• Financing or Fundraising: Verifying business assets, liabilities, or the truth of statements in investment agreements.
• Intellectual Property: Confirming use or originality in disputes over trade marks or copyright.
• Statutory Declarations: Providing facts to HMRC, insurance companies, or local authorities where official verification is needed.
• Name Changes (Personal or Business): Making a formal name change affidavit when updating business records.

In short, if you need to formally assert that something is true - and have it accepted by a court, authority, or commercial partner - an affidavit is often the go-to document.

What Is Included in an Affidavit?

An affidavit comes in a standard format, but it should always be customised to your situation. Here’s what you’ll typically find in a UK affidavit:

• The title (“Affidavit of ” and details of any case, if relevant).
• Your details: full name, address, occupation, and position (if relevant to a business).
• A statement confirming you’re making it voluntarily and understand it will be used as evidence.
• The numbered statements of fact you are swearing to be true (each should be clear and specific).
• The final “swearing” or “affirming” paragraph (“I believe that the facts stated in this affidavit are true…”).
• Signature section - to be signed in front of an authorised person (see below).

If you’re unsure how to write an affidavit, don’t worry - most solicitors or notaries will provide an affidavit form or template specific to your situation. However, for important business matters, it’s wise to consult a legal expert to ensure your affidavit covers all necessary details and is structured correctly.

Who Can Sign and Witness an Affidavit in the UK?

Not just anyone can witness or sign off on an affidavit in the UK. The process is designed to ensure the document’s authenticity. Here’s how it works:

• The affidavit must be signed ('sworn' or 'affirmed') in the presence of someone legally authorised.
• Typically, this is a solicitor, a commissioner for oaths, or a notary public.
• The authorised person will check your ID, ensure you understand the content, and witness you sign.
• They will then sign themselves, marking when and where the affidavit was sworn (or affirmed, if you object to swearing oaths for religious reasons).

If you’re making a business affidavit, for example relating to company records or litigation, always check that the witnessing party is accepted by the recipient (court, Companies House, bank, etc.). The rules can be strict, and incorrect witnessing could invalidate the affidavit.

How Do You Write an Affidavit in the UK?

Writing a clear affidavit is all about setting out facts simply, truthfully and in a format the court or recipient expects. Here’s a straightforward process you can follow:

1. Title Your Document Clearly: For example, “Affidavit of in the Matter of ”.
2. State Who You Are: Begin with your full name, home/business address, occupation, and your role in the case or business.
3. Number Your Statements: Present the facts as a series of short, numbered paragraphs. Each should address a single point and avoid speculation or opinion.
4. Declare the Truth: End with a statement such as “I solemnly and sincerely declare that the contents of this affidavit are true to the best of my knowledge and belief.”
5. Leave Space for Swearing: The final lines should be left for the signature, date, and details of the witnessing official.

Remember, an affidavit is a legal document - any false statement could amount to perjury, which is a criminal offence. If your situation is complex or could have major business consequences, get help from a commercial lawyer to draft your affidavit.

How to Get an Affidavit Signed and Sworn in the UK

Once your affidavit is written:

• Make an appointment with a solicitor, notary public, or commissioner for oaths.
• Bring valid ID and the unsigned affidavit with you.
• In the official’s presence, sign the affidavit and swear or affirm the truth of its contents.
• The official will sign and stamp it, completing the process.

This process is what makes your written statement a formal piece of evidence, distinguishable from an ordinary letter or statement.

How Much Does an Affidavit Cost in the UK?

If you’re wondering how much it costs to get an affidavit in the UK, the answer is usually "not much" for a straightforward swearing process:

• The statutory fee for swearing an affidavit before a solicitor or commissioner for oaths is currently £5 per affidavit and £2 per exhibit (as per the Solicitors Regulation Authority).
• Notaries (for international/business purposes) may charge more - shop around or ask in advance.
• If your affidavit is being drafted by a solicitor due to its complexity, additional fees will apply for preparing the document itself.

Important: If your affidavit involves important company matters, litigation, or needs to be used overseas, professional drafting is worth the investment to ensure it’s accepted and protects your position.

What Are Some Common Types of Affidavits Used by Businesses?

There are many situations where affidavits play a role in business life. Some of the most common examples include:

• Affidavit for Name Change: Swearing to the facts of a name change (either personal or company) - often required when updating official records.
• Affidavit of Support Sample: Confirming financial support for business visas, trade finance, or loan applications.
• Affidavit of Service: Documenting that a legal notice or document has been properly delivered.
• Affidavit for Disputes or Litigation: Providing sworn evidence in a business dispute, shareholder litigation, or regulatory matter.
• Statutory Declaration or Statement of Truth: While technically distinct from affidavits, these are used in similar business or administrative settings and should follow similar principles of honesty and structure.

Each type will have its own formatting quirks and requirements, so when in doubt, check with your legal adviser or the institution requesting the affidavit.

What’s the Difference Between an Affidavit and a Statutory Declaration?

It’s easy to confuse the two, as both are sworn written statements. The main differences are:

• Affidavit: Sworn on oath (or affirmation) before an authorised person and often used directly in court proceedings.
• Statutory Declaration: Also a legal document, but used for administrative or regulatory contexts rather than as evidence in court. It does not require swearing an oath, but is still legally binding and governed by the Statutory Declarations Act 1835.

For most business purposes, the distinction is mainly about procedure, but the consequences for making a false statement are serious in both cases - always tell the truth.

Sample and Example of an Affidavit in the UK

If you’re after a “example of affidavit” or just want to see how it looks in practice, here’s a simple template (for illustration only):

Affidavit of John Smith In the Matter of ACME Limited
I, John Smith, of 23 Market Street, Manchester, M2 1AB, Director of ACME Limited, MAKE OATH (or solemnly affirm) and say as follows:
1. I am a director of ACME Limited (“the Company”). 
2. On 1 June 2024, I attended a board meeting of the Company (see attached minutes).
3. At that meeting, the following resolution was passed: 
4. To the best of my knowledge and belief, the facts stated in this affidavit are true.
Sworn (or Affirmed) at: 
Date: 
Signed: _____________________
Before me: 
Print Name:
Office:

This is a simplified version. Always adapt your affidavit for the specific facts, requirements, and formalities requested by the receiving party or court.

Legal Requirements and Pitfalls for UK Affidavits

Affidavits are strict legal documents, and careless preparation can have serious consequences. Here are some key points to keep in mind:

• Never lie or exaggerate. Making a false statement in an affidavit is perjury.
• Double-check your facts. Only include statements you know are true - if in doubt, say so.
• Tailor your affidavit. A template can help, but each affidavit should fit its specific purpose and follow the rules required by the court, Companies House, or other authorities.
• Get the right witnessing. If in doubt, use a solicitor or notary public to avoid the document being rejected for improper witnessing.
• Keep your records. Always keep an original or certified copy in your business files for future reference.

Drafting affidavits can sometimes intersect with other key legal documents. If you’re not sure whether you need an affidavit, a statutory declaration, or another formal statement, reach out to a legal expert.
