A notary public is a qualified legal professional who authenticates documents and signatures for use in foreign or cross-border transactions, and certifies facts in a form relied on by courts, registries, and public authorities. In England and Wales and in Ireland, notaries are usually solicitors (or similarly qualified lawyers) with additional notarial training and appointment; in Scotland and Northern Ireland, notaries public are typically practising solicitors with restricted notarial functions unless specially authorised.The role is governed mainly by statute and professional regulation (for example, the Public Notaries Acts and rules made by notarial regulators), rather than a single exhaustive legislative definition. Core functions include: attesting signatures; certifying copies; taking affidavits, oaths and affirmations; preparing and notarising powers of attorney; and issuing notarial acts and authentications for use abroad, often followed by legalisation (apostille or consular).Notaries public are impartial officers of the law, owing duties of independence, verification and record-keeping. Their acts carry evidential weight domestically and internationally, making them central to cross-border commerce, property transactions, banking, shipping and private client matters involving foreign jurisdictions.
