How to find a trustworthy interpreter in Spain

Key rules

• Official validity: Only a sworn translator-interpreter appointed by the foreign ministry can produce translations that Spanish authorities accept as official.
• Language pair: A sworn appointment covers a specific language pair, so check that it matches the languages you need.
• Quote: Get the rate, minimum charge and extras in writing before you book.
• Agencies: Ask an agency who the actual interpreter will be before you agree.

Start with what you need the interpreter for

Decide first whether you need someone to speak for you at an appointment, or a written translation that Spanish authorities will accept. The first is interpreting. The second usually needs a sworn professional. Mixing them up is the most common and costly mistake.

Sworn or not sworn

A sworn interpreter is only needed when the work must have official validity. The legal title is traductor-intérprete jurado. It is one professional title, not two separate qualifications.

• Sworn work is mostly written. The translation carries the translator's signature and seal, and Spanish authorities accept it. Sworn professionals can also interpret orally, for example at a notary or in court, but most of their work is on paper.
• Non-sworn work is fine for doctor visits, business meetings, viewings and everyday admin where nobody asks for an official document.

If an office, notary or court asks for a traducción jurada, a non-sworn translation will be refused. Ask the office what it needs before you book.

Where to find a sworn interpreter

The Spanish foreign ministry appoints sworn translators-interpreters. Its official list is on its website and you can search by language, name and province. Each appointment covers a specific language pair, so check that the pair matches yours. The list is updated from time to time, so use the current version.

People qualify with a Spanish university degree in translation and interpreting, or by passing the ministry's exam if they do not have the degree.

Where to find a non-sworn professional

• Professional associations. Their member directories are a good start. Look at APTIJ, ASETRAD, ACE Traductores and AIIC (the international conference interpreters' association).
• Agencies. They are quick and can cover rare languages, but they add a margin to the price.
• Direct freelancers. Often cheaper, and you know who turns up.

For a public health appointment, ask for an interpreter when you book or at the admissions desk. The checklist below covers this and how much notice to give.

How to vet someone

Ask for the following before you agree:

• A degree in translation and interpreting, or another recognised qualification.
• Sworn status, if you need official validity. You can check it in the ministry list.
• Membership of a professional association.
• References or experience in your subject, such as medical or legal.
• A written confidentiality commitment.
• Professional liability insurance.
• A clear written quote with the terms.

With an agency, also ask who the actual interpreter will be and whether the agency is a registered company. The documents list below sets out what to request in writing.

What it costs

Interpreters usually quote per hour, half-day or full day, depending on the type of work. Rates vary with the language, the city and the subject.

• Consecutive interpreting (speaking in turns) and liaison work (helping two people talk) usually cost less than simultaneous interpreting. Simultaneous normally needs two interpreters for longer sessions.
• Many interpreters set a minimum charge, often one to two hours or a half day.
• Extras are common: travel time and expenses, preparation for technical material, urgent bookings, and weekend or evening work.

Ask for a total price in writing, with the minimum and all extras listed, so there are no surprises. Compare two or three quotes. Rates are not fixed, so treat any typical figure as a starting point.

Friends, charities and gestores

A friend or a free charity service can help with simple situations, but they cannot give you official validity or a confidentiality commitment. The comparison below shows when each option makes sense.

Professional interpreter, friend, free charity help or paperwork agent (gestor) compared

The right helper depends on what you need done. A professional interpreter is for formal or high-stakes settings, a friend for everyday conversations, a charity for free help if you qualify, and a gestor for handling paperwork for you.

Side by side

Professional interpreter

Choose a professional when the stakes are high or the subject is technical. Rates depend on the language, the city and the subject.

• Agencies add their own margin, so ask for a total price in writing.

Friend or relative

A friend is fine for ordinary errands. No general rule bans it, and many offices tolerate it. But you have no right to it, and staff can say no. Practice varies by office.

A friend is generally not accepted for formal statements in courts or police procedures. Interpreters there should be qualified and independent. Ask the office in advance if you plan to bring someone.

Charity or town hall help

Free help is worth trying first if you qualify. Cruz Roja, CEAR and Accem run programmes for migrants, asylum seekers and refugees. They offer reception, legal and social guidance, and help with admin tasks, often with interpreters or cultural mediators.

Access is mainly for asylum seekers, refugees, people with international protection and vulnerable migrants. Some programmes need a referral from social services. Eligibility and languages vary by city and by programme, so contact the local office of each organisation to see what it offers now.

Gestor

A gestor is a paperwork agent. Choose one when you want someone else to handle the forms, the fees and the follow-up. They do not interpret for you in meetings.

• Simple paperwork, such as an NIE application or a certificate, generally costs less than residency applications, renewals or nationality files.
• Fees depend on the task, the region and the office.
• Some gestores add charges for translations, appointments and travel.
• Get written quotes from several gestores and check what each one includes.

How to choose

• Everyday errand, low risk: bring a friend, and check with the office first.
• Formal, technical or high-stakes: book a professional interpreter.
• You may qualify for charity support: start with the local office, since it costs nothing.
• A pile of forms and no wish to deal with them: hire a gestor.

Sworn translation of documents and legal advice from a lawyer are separate services, covered on other pages.

Documents you need

• Proof of sworn status, if the work needs official validity: the interpreter's appointment, which you can check on the Ministry of Foreign Affairs list of sworn translators-interpreters for the right language pair.

• Sworn translation of any document that Spanish authorities must accept: a written translation carrying the sworn translator's signature and seal.

• Proof of qualification: a degree in translation and interpreting or another recognised qualification.

• A written confidentiality commitment from the interpreter or agency.

• A clear written quote with the rate and terms.

• Proof of professional liability insurance from the interpreter or agency.

Checklist for arranging an interpreter before an appointment

Before your appointment

• Name the exact language you need, and the dialect or regional variety if it matters, when you book.

• For a public health appointment, ask at booking or at the admissions desk (admisión or atención al paciente) for an interpreter or mediator in your language.

• Ask the provider how much notice they need. Private agencies often want at least a few days to a week, and more for rarer languages or sworn interpreting.

• Book earlier for specialist subjects, rare languages or sworn interpreting, and allow several days if you also need a sworn translation of documents.

• Check the interpreter's qualifications: a degree in translation and interpreting, and sworn status if the work needs official validity.

• Get a clear written quote that shows the rate, the minimum charge, and any extras for travel, urgent booking or evening and weekend work.

• Ask for a written confidentiality commitment before you share any personal details.

• Plan a backup if no professional is available: bring a trusted adult, but use a professional for consent and sensitive medical matters.

Lead times and booking steps vary by region and provider, so confirm them with the clinic, office or agency when you book.

Frequently asked questions

Is a sworn interpreter the same as a sworn translator in Spain?

Yes, in Spain they are the same professional, with one legal title: traductor-intérprete jurado. Most of their work is written translation with a signature and seal that Spanish authorities accept. Oral interpreting by a sworn professional is possible, for example at a notary or in court.

Where can I find a sworn interpreter in Spain?

You can search the official list of sworn translators-interpreters published by the Ministry of Foreign Affairs. You can filter it by language, name and province.

How are interpreters in Spain usually priced?

Interpreters usually charge per hour, half-day or full day, depending on the type of interpreting. Simultaneous interpreting costs more than consecutive or liaison work and often needs two interpreters for long sessions. Minimum charges of one to two hours are common, and agencies add a margin.

Which professional associations can I check when vetting an interpreter?

You can check whether the interpreter belongs to an association such as APTIJ, ASETRAD, ACE Traductores or AIIC.
