The new Commercial Register Act (Act No. 29/2026 Z. z.) takes effect on 17 August 2026. For companies and their shareholders, it is the largest change to corporate administration in recent years. These are the points likely to affect you first.
Key documents now require authorisation
The most important change is that formation documents, ownership interest transfer agreements and selected corporate decisions can no longer simply be signed with officially certified signatures. The Act requires lawyer authorisation or a notarial deed.
In practice, a lawyer or notary assumes responsibility for the document’s content, assesses compliance with the law, verifies the identities of those acting and authorises the document. The aim is to limit fraudulent company transfers and errors that currently delay register court proceedings.
One qualification matters: the choice of lawyer or notary applies to formation documents, ownership interest transfer agreements and decisions of a sole shareholder. However, certain general meeting decisions in an s.r.o. with multiple shareholders, such as appointing or removing a director or changing the ratio of ownership interests, require a notarial deed exclusively. Lawyer authorisation is insufficient in those cases.
Company name reservations
A new option allows you to reserve a company name before formation. This is useful when preparing larger projects and needing certainty that no one else will take the name in the meantime.
Fees and fines
The Act also changes rates: court fees fall for several types of action, while penalties for failure to meet register obligations become stricter. We recommend checking that all registrable details of your company are correctly entered. An error may now cost more than before.
What to do now
- Proceedings commenced by 16 August 2026 will be completed under the previous rules. Applications filed later fall under the new Act.
- Check your commercial register details, including directors, registered office and shareholders. We handle any commercial register changes, including the filing.
- When planning corporate changes, allow time for lawyer authorisation and remember that an application cannot be supplemented or withdrawn: it must be correct the first time.
As a law firm, we authorise documents directly, including where we prepare the entire corporate change. If you are unsure which of your planned steps the new Act affects, contact us.
