Affidavit (Ireland)

An Affidavit in Ireland puts facts on the record under a formal declaration so they can be relied on by a court, registrar, or third party, and is governed by the Oaths Act 1888.

The formal requirements for affidavits in the superior courts (the High Court, Court of Appeal, and Supreme Court) are set out in Order 40 of the Rules of the Superior Courts (S.I. No. 15 of 1986, as amended by subsequent statutory instruments). Order 40 governs the form of affidavits, the persons authorised to administer oaths, the contents that are permitted, the use of exhibits, and the swearing of affidavits outside Ireland. The rules of the Circuit Court (Circuit Court Rules 2001, as amended) and the District Court (District Court Rules 1997, as amended) contain equivalent provisions for affidavits in those courts.

In Irish court proceedings, affidavits are used extensively in a wide range of contexts. In High Court proceedings commenced by way of summary summons (for example, claims for a liquidated sum), the parties exchange affidavits of claim and defence instead of oral evidence at the initial hearing stage. In judicial review proceedings, all evidence is by way of affidavit, with oral evidence permitted only in exceptional circumstances. In family law proceedings (divorce, separation, wardship, guardianship), affidavits are used to place evidence before the court regarding the parties' circumstances, the child's welfare, and the grounds for the application. In probate proceedings, affidavits of attesting witnesses, affidavits of due execution, and affidavits of the executor or administrator are required. In bankruptcy and company law proceedings, affidavits are used to establish the debtor's assets and liabilities.

The Criminal Justice (Perjury and Related Offences) Act 2021 modernised the law on perjury in Ireland, replacing the previous common law offence with a thorough statutory framework. The 2021 Act provides for a maximum penalty of ten years' imprisonment for perjury and for related offences such as making false statements in judicial proceedings. The Act reinforced the serious consequences of making a false affidavit and underlined the importance of the oath as a guarantor of the truth of sworn evidence.

For persons who have a conscientious objection to taking an oath, section 4 of the Oaths Act 1888 (still in force in Ireland) provides that a person may make a solemn affirmation instead of taking an oath. An affirmation has the same legal effect as an oath for all purposes, including the taking of perjury proceedings. The deponent should inform the commissioner for oaths of their wish to affirm rather than swear.

Affidavits in Ireland are also used in a range of quasi-judicial and administrative proceedings. The Revenue Commissioners accept affidavits in connection with the administration of estates, including affidavits of valuation for Capital Acquisitions Tax (CAT) purposes under the Capital Acquisitions Tax Consolidation Act 2003. The Companies Registration Office (CRO) requires affidavits in connection with certain filings under the Companies Act 2014. The Workmen's Compensation Tribunal and other statutory bodies also accept affidavit evidence in appropriate circumstances.

Outside the court system, affidavits are commonly used to verify facts for official or administrative purposes — for example, confirming a change of name, establishing an identity, confirming a lost document, or verifying eligibility for a public service. These uses are distinct from the use of statutory declarations (governed by the Statutory Declarations Act 1938), although in practice many people use the terms interchangeably. A solicitor or commissioner for oaths can advise on whether an affidavit or a statutory declaration is the appropriate document for a particular purpose.

The cost of swearing an affidavit before a solicitor in Ireland is regulated by the Solicitors (Professional Practice, Conduct and Discipline) Regulations. A solicitor may charge a modest fee for administering the oath and examining the affidavit to confirm it is in proper form. Commissioners for oaths charge a fee prescribed by the relevant Court Rules. Swearing an affidavit is a straightforward process but requires the deponent to attend in person before the authorised person; an affidavit cannot be sworn remotely or by electronic means under current Irish law.

An Affidavit is needed whenever you are required to present sworn written evidence in Irish court proceedings, or when an institution or authority requires a sworn statement of fact from you. Unlike a statutory declaration (which is used for non-court administrative purposes under the Statutory Declarations Act 1938), an affidavit is specifically a court document — its primary purpose is to place evidence before a court in a legally admissible form.

You need an Affidavit when you are commencing or defending proceedings in the High Court by way of summary summons. Summary proceedings require the parties to exchange affidavits of debt (by the plaintiff) and affidavits of merits (by the defendant) in lieu of a full oral trial at the initial stage. A well-drafted affidavit of debt setting out the amount owed, the basis for the claim, and the relevant documentary evidence is essential for a plaintiff seeking summary judgment under Order 37 of the Rules of the Superior Courts.

You need an Affidavit when you are bringing or opposing a judicial review application in the High Court under Order 84 of the Rules of the Superior Courts. All evidence in judicial review proceedings is by affidavit, and the Statement of Grounds verifying affidavit is a fundamental procedural document. The affidavit must be drafted carefully to include all relevant facts, to exhibit all relevant documents, and to avoid including inadmissible opinion evidence or legal argument.

You need an Affidavit in family law proceedings — divorce (under the Family Law (Divorce) Act 1996), judicial separation (under the Family Law Act 1995), nullity, guardianship, custody, access, and maintenance applications before the Circuit Court or High Court. Both parties are required to swear affidavits of means (setting out their financial circumstances) and affidavits of welfare (concerning the arrangements for the care of dependent children).

You need an Affidavit in probate proceedings — to prove the due execution of a will, to establish the identity and entitlements of the next of kin on an intestacy under the Succession Act 1965, or to obtain a grant of probate or letters of administration in the Probate Office of the High Court. The Probate Office has specific requirements for the form and content of affidavits in probate applications.

You need an Affidavit in debt enforcement proceedings — when applying to the Circuit Court or District Court for a judgment mortgage under the Land and Conveyancing Law Reform Act 2009, an attachment of earnings order, or an instalment order. The creditor must swear an affidavit confirming the amount of the judgment debt, the date of the judgment, and the steps taken to enforce it.

You need an Affidavit when responding to a witness summons in civil or criminal proceedings, when applying for an injunction in the High Court, or when seeking a return date in any interlocutory application. Affidavits are also required in applications to the Companies Registration Office (CRO) under the Companies Act 2014 and in Revenue Commissioners applications relating to the administration of estates for Capital Acquisitions Tax purposes under the Capital Acquisitions Tax Consolidation Act 2003. In all these contexts, the affidavit is the primary vehicle for placing your version of events and supporting evidence before the court or authority in a legally admissible, sworn form.

A valid Irish Affidavit must comply with the formal requirements of Order 40 of the Rules of the Superior Courts (or the relevant court rules for the court in which it is to be used) and contain the following essential elements.

The title and heading must identify the court proceedings in which the affidavit is to be used — stating the name of the court (for example, 'In the High Court', 'In the Circuit Court', 'In the District Court'), the record number of the proceedings, and the names of the parties (plaintiff and defendant, or applicant and respondent). Where the affidavit is filed in support of a first application (before proceedings are commenced), the title should indicate the nature of the application.

The introductory paragraph identifies the deponent — the person making the affidavit — by full legal name, address (including Eircode), occupation, and their role in the proceedings (plaintiff, defendant, solicitor, witness). The introductory paragraph should also confirm that the matters deposed to are within the deponent's personal knowledge, save where otherwise indicated.

The body of the affidavit sets out the relevant facts in numbered paragraphs — each paragraph dealing with a distinct factual matter. The contents must be confined to facts within the deponent's personal knowledge (or, in interlocutory proceedings, matters on information and belief with source stated). The affidavit must not contain legal argument, submissions, or opinions. Relevant documents should be exhibited — attached to the affidavit and identified by exhibit marks (for example, the document marked AB1 now produced and shown to me).

The exhibits list, required by Order 40 Rule 11, must identify each exhibit attached to the affidavit by its exhibit mark, description, and date. Exhibits should be properly marked and attached in order.

The jurat is the formal attestation clause at the end of the affidavit. Under Order 40 Rule 4 of the Rules of the Superior Courts, the jurat must state: the date and place of swearing; the name and capacity of the commissioner for oaths, solicitor, or other authorised person before whom the affidavit was sworn; and the signatures of both the deponent and the commissioner. The jurat must be in the prescribed form: 'SWORN/AFFIRMED by the above-named deponent [name] at [place] on the [date] day of [month] [year], before me, a [Solicitor/Commissioner for Oaths] and I know the deponent.'

The signature of the deponent must appear at the end of the body of the affidavit and again in the jurat. If the deponent cannot sign (because they are illiterate or have a physical disability), the procedure for marking (placing a mark) with a witness is available under Order 40.

For affidavits to be used in courts other than the superior courts, the relevant court rules (Circuit Court Rules, District Court Rules) should be consulted to confirm compliance with any additional or different requirements.

The filing fee for affidavits in the High Court is prescribed by the Courts Act Fees Order. Solicitors who prepare affidavits on behalf of clients must comply with the Solicitors Acts 1954 to 2015 and the professional conduct requirements of the Law Society of Ireland. A solicitor who administers the oath for an affidavit in proceedings in which the solicitor is acting must be mindful of the risk of conflict of interest. For straightforward matters, a commissioner for oaths can be found through the local courthouse or through the Law Society of Ireland's directory of solicitors holding that appointment.
