Czech co-working and registered-office rules

Anyone who has set up a company in Prague knows the moment when the notary, lawyer or registration agent asks: "And where is the seat?" A founder without an office assumes it is a formality. It is not. The seat is the address at which the company legally exists, receives official post and can be served with legal documents, and a good deal of later trouble with banks, courts and tax offices starts there.

This explainer covers the main rules for registered offices, including co-working and virtual-office arrangements. It is general information, not legal advice. For a specific arrangement, have a lawyer check the contract and the form of consent.

What the seat is

The registered office (sídlo) is the legal entity's address as recorded in the commercial register. Under the Civil Code (Act no. 89/2012 Coll.) a legal entity must have a seat, and the address is part of the registered data. It differs from a place of business (provozovna), the premises where the company actually trades, which is registered separately through the trade licence. A small firm might use one address for all of these, or for none.

A Czech company's seat must be in Czechia. It determines the competent registry court and the local tax office, which is one reason a Prague seat is attractive. It is also where official letters are sent, although the data box (datová schránka), which every company must have, is the main channel for official communications.

Proving the right to use the address

When a company is entered in the register or changes its seat, it must show a legal title to use the premises: the owner's consent to placing the seat at the address, or a lease or other right of use that allows it. In the standard route the property owner gives written consent, and the registry court or notary checks the documents in the form the law requires. The requirements for the owner's signature have changed over time, so check the current form with the court or your notary (as of 2026; check the official source).

Evidence of ownership is available from the land registry. If you rent the premises, the lease must allow you to use them as a seat, and the owner's consent is typically needed too. A tenant cannot designate a seat without the owner's agreement, however good the lease. See how to read a property extract for the document that identifies the owner.

Co-working and virtual offices

Co-working operators and virtual-office providers sell the service of a seat. The arrangement is lawful as long as the operator has the right to let others use the address as a seat and the paperwork exists. If the operator is itself a tenant, it needs the landlord's permission to sublet or to let third parties register there. The founder should ask the operator for:

• confirmation of the operator's own right to the premises;
• the owner's written consent to the seat, in the form the court accepts;
• a clear description of what the service includes, such as mail handling, scanning and meeting-room hours;
• the term, price and notice conditions of the agreement.

A cheap address may come with weak documentation. An address with dozens or hundreds of companies registered at it is common in the market and legal, but it can prompt extra questions from banks and counterparties, as discussed in opening a business bank account.

Residential addresses

Many small companies use their own flat as a seat. You need the owner's consent: your own, if you own it, or the landlord's if you rent. In a building with an owners' association, the building's rules and the tenancy contract also matter. A home seat has a privacy cost too, since the commercial register is public and shows the address. Decide whether you are comfortable with that.

If the seat is wrong

The registry court can step in if a company's seat does not meet the legal requirements, for instance when the owner says consent was never given or has been withdrawn. An owner who finds a company registered at his property without agreement can ask the court to deal with it. The court can intervene, and in serious cases a company can be dissolved; check with a lawyer for your situation. A company that cannot be reached at its seat also risks having official documents treated as delivered anyway under the delivery rules, which can mean missed deadlines.

Providers sometimes change premises. If the right to use the address ends, the company must register a new seat in time. Ask your provider how it will tell you.

Changing the seat

A move needs a change in the commercial register and fresh proof of the right to the new address. The company must also update its trade licences, tax registration, bank, website and invoices. Our guide to the commercial register explains how entries work, and registering an s.r.o. shows where the address enters the sequence.

For founders

Decide the seat before you meet the notary, because the consent document takes time. Get the owner's consent in the form the court requires, not an email. Keep a copy of the lease or service agreement with the corporate records. Once a year, check that the right of use is still in place.
