Private investigation agencies in Ticino: the law, and how to choose one

Nobody looks for a private investigation agency for fun. There is usually a debtor who has stopped answering, a business partner behaving oddly, an invoice that does not add up, or a family situation that needs documenting before it reaches a courtroom. And underneath it all, one question: are these people legitimate? Can I trust them?

That is a fair question. In Ticino, the profession is seriously regulated — far more seriously than most clients assume. In the other Swiss cantons, by contrast, each one governs the profession under its own rules, where such rules exist at all: there are cantons where opening an investigation agency requires no particular qualification. Industry websites do not always explain this; sometimes they simply write "we are licensed" and move on.

This page does the opposite. I will walk you through how the Canton of Ticino regulates the profession, what an agency is legally allowed to do, and how to verify on your own — in two minutes, without asking anyone's permission — whether the firm in front of you is in good standing.

A word about who is writing. I am the founder of Minerva.agency, the website through which InSpace.Center LLC operates as a private investigation agency in Ticino, based in Chiasso. The company is entered in the cantonal register. And I work alone: the person who runs your case is the person you speak to on the phone.

Why the Swiss angle matters if you are not Swiss

If you are reading this in English, there is a reasonable chance you are a cross-border commuter, a foreign resident, or a lawyer instructing from abroad. Two features of the Swiss system tend to surprise people, and the article above already touches on the first:

Regulation is cantonal, not federal. There is no single national licence. Twenty-six cantons, twenty-six regimes — and, as noted, some cantons impose no requirement at all. A firm licensed in Zug is not automatically entitled to operate in Ticino: it must at minimum notify the Ticino authorities first. Any agency that tells you it holds "a Swiss licence" is being loose with the truth.

Federal privacy and civil law sit on top of the cantonal rules. The revised Federal Act on Data Protection and the personality-rights provisions of the Civil Code apply to everything an investigator does. A cantonal licence lets you practise. It does not let you breach someone's privacy.

If your matter touches Ticino — a person, a company, an asset, an address — you want a Ticino-licensed agency. Not one that "also covers" Ticino from Milan or Zurich.

The governing statute: LPPS

Until 2021, private investigation in Ticino ran on a 1976 statute, the LAPIS. Then the cantonal parliament passed the Act on Private Security and Investigation Services (LPPS) of 9 November 2020, in force since 1 June 2021.

The change was not cosmetic. The old law was written before mobile phones, before the internet, before "personal data" was a legal concept. The new one sets mandatory training requirements, a cantonal database, insurance obligations, and a penalty regime that bites.

For you, sitting on the other side of the table, the practical consequence is blunt: in Ticino, an investigation agency without a cantonal licence is not operating informally. It is operating unlawfully.

Who must be licensed, and for what

Article 7 LPPS makes security and investigation work carried out in the canton — by individuals or companies — subject to prior authorisation. It is not something you register afterwards; it is a permit you must hold beforehand.

Article 8 distinguishes four types of licence:

• agency licence, for the security and/or investigation firm itself;
• agency director licence, for the responsible representative;
• employed security agent or private investigator, working for an agency;
• self-employed practitioner.

These are separate levels and are not interchangeable. Someone licensed as an employed investigator cannot open and run an agency; an agency in corporate form cannot operate without a designated responsible representative.

There is also a limit that catches many people off guard. Under Article 2(4), only investigation work commissioned by private parties is permitted. A Ticino agency cannot take an investigative mandate from a public authority. The sole reservation concerns surveillance under federal social-insurance law — which in any case requires a specific authorisation issued at federal level.

What an agency must prove before it can operate

Article 11 sets out the conditions. Each one is worth reading carefully, because each is a protection that lands on your side of the table.

Professional liability insurance. If an investigation is botched and you suffer loss falling within the scope of that liability cover, there is protection behind it. This is precisely why relying on a friend "who is good at finding things online" leaves the entire risk with you.

Registration in the cantonal commercial register. No shell structures, no generic foreign VAT number standing in for a company. An identifiable legal entity you could actually sue.

A principal place of business in Ticino — or a Swiss head office with a Ticino branch. A barrier against agencies that show up with a local phone number and no real presence on the ground.

A designated responsible representative holding signing authority: a named individual answerable to the authorities, where the agency operates in corporate form.

The responsible representative and CPSicur training

This is the part almost nobody explains to clients.

The canton's Institute for Continuing Education in Camorino runs three levels of mandatory basic training for the sector, split into two tracks: A for security, B for investigation.

• CPSicur I — employed investigator;
• CPSicur II — self-employed investigator;
• CPSicur III — responsible representative, i.e. someone entitled to direct an agency.

Holding level III means having the training required to run an investigation agency and, where relevant, to employ agents. It is not a certificate bought online: each of these credentials is issued only after assessment by the competent authorities, and since 2021 licence renewal also requires certified continuing education.

I hold CPSicur level III. I state it because it is a verifiable fact — one I can demonstrate by showing my official card.

Verifying an agency in two minutes

Here is the practical part. Before signing anything, you can check everything yourself.

1. The cantonal register. The Ticino cantonal police publish the list of authorised security and investigation agencies online. It is public and needs no login. If the agency's name is not there, the conversation can end right there. You will find it on the Department of Institutions portal, under the arms, explosives and private security service: consult it here.

2. The legal name, not the trading name. Some agencies operate under a brand different from their registered company. Ask which entity issues the invoice, and search for that one. In my case: the website through which I offer my services is Minerva.agency, and the licensed company is InSpace.Center LLC, CHE-174.871.005.

3. The official identity card. Article 24 LPPS provides that every licence holder receives an official card. Article 25 adds that agencies must issue their staff a card identifying which agency they act for. Asking to see it at a first meeting is entirely normal.

4. The commercial register. Zefix is free and tells you in thirty seconds whether the company exists, where it is domiciled, who holds signing authority, and since when.

5. The validity period. Under Article 16, a licence is valid for three years and is not transferable. It is not a permanent title. An agency showing you a 2019 document is not showing you a valid licence.

What a Ticino agency legally cannot do

An agency that promises everything is an agency that will land you in trouble. These are the limits set by law, which no serious professional crosses.

It cannot use force or exercise police powers. Article 21 requires respect for the state monopoly on the use of force. Direct enforcement is permitted only in narrowly listed situations — self-defence, necessity, exercise of domiciliary rights, provisional arrest under Article 218 of the Code of Criminal Procedure — and always subject to proportionality.

It cannot pose as authority. Article 26 expressly prohibits the use of the word "police" or any derivative, and requires uniforms, emblems, cards and vehicles to be clearly distinguishable from those of the police. Article 20(3) prohibits anyone without a licence from behaving in a way that leads others to believe they hold one.

It cannot compel anyone to cooperate. Again under Article 20: on request, the investigator or security agent must state their identity and inform the person concerned that they are free to refuse — in particular to refuse identity checks and personal searches.

It cannot obstruct an official investigation. Article 19(2) is unambiguous: where a private investigation interferes with the functions of judicial or police authorities, the public prosecutor may order the investigator to stop. The same article requires that any item or information of potential criminal relevance be passed to the cantonal police.

It cannot access restricted databases. No Swiss private agency has access to criminal records, banking data, medical registers, telephone metadata or traffic data. Anyone offering this is either lying or proposing a criminal offence — and in the second case, the client is exposed alongside the operator.

It cannot intercept communications. Interception is reserved to the judicial authority, full stop.

The penalties are not symbolic. Article 28 provides for fines from CHF 50 to CHF 20,000, with a minimum of CHF 500 for practising without a licence and CHF 2,000 for a responsible representative in breach of duty. Attempt, incitement and complicity are all punishable.

Large firm or single practitioner?

You will come across agencies advertising offices scattered around the world. It is worth asking what those offices do for you if your problem is a debtor who moved from Mendrisio to Zurich.

The two models follow different logics.

A larger structure earns its keep when you need simultaneous capacity: surveillance on several subjects at once, round-the-clock coverage for weeks, presence in multiple cantons on the same day. If your matter is genuinely that size, go and find one.

A single practitioner makes more sense for everything else, which is most cases. The advantage is not price — it is the chain of custody over your information. Inside a larger firm, a case travels from the salesperson to the coordinator to the field operators, and your name, along with your counterparty's, circulates among people you will never meet. With a single practitioner the file stays in one head and one archive.

I work this way deliberately: a small number of cases at a time, each carried from the first conversation to the final report by the same person. It means occasionally saying no, or asking someone to wait. It also means I have never had to explain to a client why the colleague handling their case no longer works here.

Six questions to ask at the first contact

Take them with you. The answers will tell you more than any website.

1. Under what registered company name are you listed on the cantonal register? If they hesitate and cannot give you a name that is actually on the register, you already have your answer.
2. Who is the responsible representative, and what CPSicur level do they hold? Worth noting: if a colleague operates as a self-employed practitioner rather than in corporate form, it is perfectly correct for them to answer CPSicur II.
3. Who will actually carry out the work, and will I be speaking to that person?
4. On what legal basis will you collect this information? A professional answers by citing rules. An amateur answers "we have our methods".
5. What will I receive at the end, and in what form?
6. What happens if the investigation produces nothing? No one can guarantee a certain outcome in an investigation. The exception is the mere retrieval of public documents you are legally entitled to — for instance an extract from the debt-enforcement and bankruptcy register, or a certificate of inheritance concerning a person of whom you are a recognised heir. You can often request these yourself from the authorities, within the limits of the law; but if you would rather entrust the matter to an agency, it can act on your behalf under a power of attorney.

One more question, this one for yourself: do I actually need what I am asking for, and will I still need it in six months? Some enquiries I receive belong not with an investigator but with a lawyer — or, depending on the situation, a couples' therapist — and I say so. I would rather lose the instruction than take a pointless one.

How I work

Four stages, every time.

Confidential first conversation. I listen, assess legal feasibility, and we define the objective. No cost, no obligation. If the case is not viable, or not mine, you hear it here.

A written investigation plan. Methods, timeline, budget. You know what will happen and what it will cost before I touch anything.

Collection. Observation, documentary analysis, open-source research. Every element gathered within legal limits, every step recorded.

Final report. A readable, ordered, verifiable document that will stand up in front of a lawyer and, if necessary, a judge.

I work across six areas: tracing absconded debtors, locating attachable assets in support of Swiss debt-enforcement proceedings under the LEF, asset and reputational due diligence, OSINT analysis, historical and archival research, and corporate training on cyber-fraud awareness. I assess couples'-infidelity matters case by case before accepting. I do not perform debt collection: I gather information, and the rest belongs to your lawyer and the debt-enforcement office.

If instead you want a more practical picture — what hiring one actually involves, from cost to timelines to the evidentiary value of what is collected — I cover it in the companion guide on hiring a private investigator in Ticino.
