Do I need to show address proof certificate somewhere?
Establishing a company in the Estonian Business Register e-environment there is no need to present address proofs.
At the same time, the official may ask for proof of affiliation with the address. You can then show the document, the address proof certificate.
It must be remembered that before finalizing the company formation application, the data submitter confirms its accuracy.
Submission of false information, which is also, for example, submission of an address to which there is no right, is a criminal offense under the laws of the Republic of Estonia.
