Quick Summary of Affidavit Of Good Faith

An affidavit of good faith is a legal document that is typically filed in a court of law to support the validity and credibility of a claim or defence. It is commonly used in civil cases, such as personal injury lawsuits or medical malpractice claims.

The purpose of an affidavit of good faith is to demonstrate that the party filing the claim or defence has conducted a reasonable investigation into the facts and believes in good faith that their allegations or defences are true and supported by evidence. This affidavit is usually required by law in certain jurisdictions to prevent frivolous or baseless lawsuits.

The affidavit must be signed under oath by the party or their attorney and should include specific details about the investigation conducted, the evidence gathered, and the expert opinions obtained, if applicable. It should also explain why the party believes their claim or defence is valid and has a reasonable chance of success.

By filing an affidavit of good faith, the party is affirming their commitment to honesty and integrity in the legal process. If it is later discovered that the affidavit was filed without a genuine belief in the truth of the allegations or defences, the court may impose sanctions or penalties on the party responsible.

In summary, an affidavit of good faith is a legal document that serves to demonstrate the sincerity and credibility of a claim or defence in a civil case. It is an important tool for ensuring the integrity of the legal system and preventing the filing of frivolous lawsuits.

An affidavit of good faith is a legal document often used in various legal proceedings and contexts, attesting to the sincerity and honesty of a party’s actions, statements, or intentions. It serves to affirm that a party is acting without deceit, fraud, or malice. This document is particularly significant in jurisdictions where demonstrating good faith is a prerequisite for certain legal actions or defences. This overview will delve into the legal underpinnings, applications, and implications of affidavits of good faith in British law.

Legal Definitions and Purpose

An affidavit of good faith is a sworn statement made by an individual, declaring that their actions or intentions are genuine and honest. It is typically used to support the credibility of a party in legal proceedings, ensuring that the court or relevant authority acknowledges the bona fides of their actions.

The primary purpose of an affidavit of good faith is to:

  • Establish Credibility: It helps to establish the trustworthiness and integrity of the party making the affidavit.
  • Support Legal Actions: It can support legal actions where good faith is a necessary element, such as in contract disputes, insurance claims, and other civil matters.
  • Prevent Fraud: It serves as a deterrent against fraudulent claims and actions by imposing legal consequences for false statements.

Legal Context and Applications

Affidavits of good faith are used in various legal contexts, including but not limited to:

  • Contract Law: In disputes involving contracts, an affidavit of good faith may be used to demonstrate that a party has acted honestly and without intention to deceive the other party. This is crucial in cases where one party alleges bad faith or fraudulent misrepresentation.
  • Insurance Claims: Insurance companies often require affidavits of good faith from claimants to ensure that the claims made are legitimate and not fraudulent.
  • Employment Law: In employment disputes, such as wrongful termination cases, an affidavit of good faith can support a party’s claim that they acted in accordance with company policies and without malicious intent.
  • Family Law: Affidavits of good faith can be pertinent in custody battles, divorce proceedings, and other family law matters, where demonstrating sincere intentions is vital.
  • Commercial Transactions: In commercial disputes, such as breach of contract or partnership disputes, an affidavit of good faith can help demonstrate that a party has acted in accordance with the terms of the agreement and in an honest manner.

Legal Requirements and Formalities

To be legally binding, an affidavit of good faith must meet certain requirements and formalities:

  • Written Statement: The affidavit must be a written document, clearly stating the affiant’s (the person making the affidavit) assertions.
  • Sworn Oath: The affiant must swear an oath or affirm the truthfulness of the statement before an authorised individual, such as a notary public, solicitor, or commissioner for oaths.
  • Signature: The affidavit must be signed by the affiant and the authorised individual administering the oath.
  • Content Specificity: The affidavit should be specific in its content, detailing the actions, intentions, or statements being attested to. Vague or overly broad statements can undermine its effectiveness.
  • Voluntary Nature: The affidavit must be made voluntarily, without coercion or duress. Any indication of compulsion can render the affidavit invalid.

The Legal Implications and Consequences

Making a false statement in an affidavit of good faith carries significant legal consequences. Under the Perjury Act 1911, knowingly making a false statement in a sworn affidavit is a criminal offence, punishable by imprisonment. This serves as a strong deterrent against dishonest affidavits and underscores the importance of honesty and integrity in legal proceedings.

Moreover, a false affidavit can lead to severe repercussions in the related legal matter, such as the dismissal of a claim, imposition of penalties, or adverse judgments. It can also damage the affiant’s credibility in future legal matters, as courts and legal authorities may view them as untrustworthy.

Practical Considerations and Best Practices

When preparing an affidavit of good faith, it is essential to adhere to best practices to ensure its validity and effectiveness:

  • Accuracy and Truthfulness: Ensure that all statements made in the affidavit are accurate and truthful. Verify the facts and details before including them in the affidavit.
  • Legal Advice: Seek legal advice when drafting an affidavit of good faith. A solicitor can help ensure that the document complies with legal requirements and effectively supports the affiant’s position.
  • Clarity and Specificity: Be clear and specific in the statements made within the affidavit. Avoid vague or ambiguous language that could undermine the document’s effectiveness.
  • Supporting Evidence: Where possible, provide supporting evidence to substantiate the statements made in the affidavit. This can include documents, records, or other corroborative materials.
  • Proper Execution: Ensure that the affidavit is properly executed, with the affiant swearing the oath or affirming before an authorised individual. Failure to properly execute the affidavit can render it invalid.

Judicial Interpretation and Case Law

British courts have interpreted affidavits of good faith in various ways, depending on the context and the specific circumstances of each case. Key judicial interpretations and case law highlight the importance of good faith in legal proceedings and the weight courts place on affidavits of good faith.

In Interfoto Picture Library Ltd v Stiletto Visual Programmes Ltd [1989] QB 433, the Court of Appeal emphasised the role of good faith in contractual relationships. Although not specifically about affidavits of good faith, the case highlighted that parties are expected to act with honesty and fairness in their dealings, which underpins the principle of good faith.

Another significant case is Yam Seng Pte Ltd v International Trade Corporation Ltd [2013] EWHC 111 (QB), where the High Court acknowledged the implicit duty of good faith in certain contractual relationships. The court’s decision underscored the importance of honesty and fair dealing, reinforcing the relevance of affidavits of good faith in supporting claims of genuine intent and conduct.

Comparative Perspective

Affidavits of good faith are not unique to British law. Many jurisdictions recognise similar documents, though the specific requirements and applications may vary.

In the United States, for example, affidavits of good faith are commonly used in various legal contexts, including insurance claims and contractual disputes. American courts also impose severe penalties for false statements in affidavits, similar to the approach in British law.

In contrast, civil law jurisdictions, such as France and Germany, may have different mechanisms for ensuring good faith in legal proceedings, often embedded within broader principles of civil procedure and contract law. However, the underlying principle of honesty and integrity remains a common thread across jurisdictions.


The affidavit of good faith is a vital document in British law, serving to affirm the sincerity and honesty of a party’s actions, statements, or intentions in various legal contexts. Its proper use and execution are crucial in establishing credibility and supporting legal claims. Understanding the legal requirements, implications, and best practices associated with affidavits of good faith is essential for individuals and legal practitioners alike.

Given the serious consequences of making false statements in affidavits, it is imperative to approach the preparation and submission of these documents with utmost care and integrity. As British courts continue to emphasise the importance of good faith in legal proceedings, affidavits of good faith will remain a significant tool in ensuring honesty and fairness in the justice system.
