Sworn vs Regular Interpreter in the Czech Republic: When You Need Which

Planning a wedding, a notary appointment, or a business meeting in the Czech Republic, and not sure whether you need a “proper” interpreter or whether a bilingual friend can help out? The answer depends on where you’re going, and in several situations Czech law simply doesn’t give you a choice. This guide explains when a sworn interpreter is legally required, and when a regular interpreter is perfectly fine.

Note: this article covers the general legal framework. For your specific appointment, it’s worth confirming the exact requirement with the institution involved — a notary, matriční úřad, or authority.

• A sworn interpreter is officially registered with the Ministry of Justice and adds a legal clause that authorities require.
• Weddings, notary appointments, court proceedings, and dealings with authorities like OAMP legally require a sworn interpreter.
• A bilingual friend cannot substitute for a sworn interpreter at these appointments — the notary or registry office is required to refuse.
• Business meetings, conferences, and informal consultations don’t require a sworn interpreter at all.

Not every bilingual person who interprets professionally counts as a “sworn” interpreter — the distinction is a formal, legal one.

A sworn interpreter (soudní tlumočník) is officially registered with the Ministry of Justice, having been appointed after meeting specific qualification requirements and passing an entry exam through the Judicial Academy. What this registration adds isn’t just competence — it’s the legal authority to attach an official clause to their interpreting, which is what authorities, notaries, and courts specifically require. A skilled bilingual professional without this registration can interpret excellently at a business meeting, but cannot fulfil this legal role.

This is the question that actually determines what you need to arrange, and the answer follows directly from Czech law rather than convention.

Under Section 7 of Act No. 354/2019 Coll., interpreting activity is legally defined as acting before a body of public authority, or in connection with a legal act taken in the form of a notarial deed (notářský zápis). That’s the precise legal boundary — if your appointment falls into either category, only a sworn interpreter fulfils the requirement.

This is worth addressing directly, because it’s the most common source of confusion, and the answer surprises people who assume it’s just a matter of comfort or preference.

No — and this isn’t a matter of the notary’s or registry office’s preference. If you show up to a notary appointment or a wedding ceremony without an officially registered sworn interpreter, the notary or matriční úřad is required to refuse to proceed. It’s not that a bilingual friend interprets less accurately; it’s that the law doesn’t recognise their role for this specific legal act, and the notary would be taking on personal professional liability by allowing it. Arranging a sworn interpreter in advance avoids this exact situation on the day.

Not every situation calls for a sworn interpreter, and paying for one where it isn’t required is an unnecessary expense.

Business meetings, negotiations, conferences, and internal company discussions don’t carry the legal requirement, so a regular professional interpreter is entirely appropriate — and often a better fit anyway, since sworn interpreters aren’t necessarily specialised in business or technical vocabulary. The same applies to phone or video consultations, unless the call itself is with an authority that requires the sworn clause.

Once you know which type of appointment you’re dealing with, arranging the right interpreter is straightforward.

Tell us the date, location, and language combination, and we’ll confirm availability and pricing, usually within an hour. For notary appointments and weddings specifically, it’s worth booking as early as possible — these tend to be scheduled tightly, and sworn interpreters for less common language pairs can be harder to arrange on short notice. If you’re preparing documents for a notary appointment alongside the interpreter, our guides on company setup, buying property, and getting married in the Czech Republic cover the document side of each situation.

We arrange court-appointed interpreters on-site or remotely, usually confirmed within an hour.
