Modern law

Where general advice and AI are not enough.

We treat modern tools, artificial intelligence and crypto as a normal part of today's business. Yet the decision, responsibility and judgement always rest with a human — and that is exactly where our added value lies.

Modern technology. It is a topic, a business and a helper alike. And that is exactly how we see it at Steiniger. It influences clients' business models both positively and negatively, so it must be handled correctly to keep business safe and stable. And because we seek out the latest technology for our own practice, we understand it better than others.

Commerce is globalising. For most entrepreneurs and companies, business is no longer a local matter. New forms of communication and a favourable legal environment allow them to expand into new markets. For that they need a partner who knows the rules of international trade — like us at Steiniger.

Fast communication. Opportunity comes, but it also leaves quickly if you don't seize it fast enough. At Steiniger we therefore have a simple rule — to help the client and communicate with them as quickly as modern technology allows.

Frequently asked questions

How does the first consultation work and what should I bring?

You book an appointment in advance through the reservation system, where you choose the area your case concerns — and you see the price of the consultation right at booking. You don't need to bring anything; it is enough if you can name what you need to solve. We will tell you the next steps directly at the consultation; they always depend on the specific case. If you have any documents to hand (contracts, decisions of authorities, correspondence), feel free to bring them — but it is not a condition.

When do I need a lawyer during a tax audit?

Ideally right after you receive the notice of the audit. What you say and submit during the audit is very hard to change later in an appeal or in court — so it pays to set the strategy before the file is closed. We represent clients during the audit, in appeals and in judicial review.

Do I need a licence to do business with crypto-assets?

It depends on the exact activity you carry out. Under the European MiCA regulation, some crypto-asset services require authorisation (a licence), others do not. We therefore assess each model individually — usually it involves regulation, AML and tax at once, and these must be addressed together, not separately.

What should a shareholder agreement contain?

Above all the decision-making process, the transfer of ownership interests, deadlock resolution and the terms of a shareholder's exit. These points seem unnecessary as long as the shareholders agree — and become decisive the moment they stop agreeing. Setting up relationships between shareholders is one of the things we do most often.

Do you also provide services in the Czech Republic?

Yes. We have an office in Prague and for clients operating on both markets we handle Slovak and Czech matters, including cross-border transactions and international taxation.

Do you also do accounting, or only legal services?

Both — we provide accounting in cooperation with the accounting firm Wellbens. This means you get the legal, tax and accounting solution from one place and don't have to coordinate it yourself. We call this model advisory under one roof.

What languages do you communicate in?

Slovak, Czech, English and German.

Do you also represent clients in court disputes?

Yes. Besides advisory and drafting contracts, we also represent clients in disputes — in commercial, tax or criminal matters. Where possible, we try to settle the dispute by agreement before going to court.

Martin Horváth

Chief accountant · head of the accounting department

Chief accountant, head of the accounting department and a specialist in accounting, finance and payroll. Martin has many years of experience in running comprehensive accounting for small and medium-sized companies, as well as in financial management and advisory.

In practice this means he keeps clients' accounts from the first documents all the way to the annual financial statements, manages payroll and prepares the basis for tax and strategic decisions. This lets him see the client's numbers in full context — and flag what needs attention before it becomes a problem.

His precision, communication and responsibility bring our clients significant comfort in everyday operations as well as in more complex accounting matters. Thanks to the cooperation of the accounting and legal sides, the client gets both the tax and legal solution from one place and doesn't have to coordinate them alone.
