Since you will not give the original one, you should make a legalized copy. Making a legal copy of your document is easy. No need to visit the notary. You can do it at any post office. The service that you should choose is Czech Point, and it is called in Czech – Ověřování dokumentu and you should say at the window ‘potřebuje úředně ověřit listinu’. The Czech post office has an appointment system and it is in English.

If you want to have a document legalized, you don’t have to bring your own copy of the document: it will be copied (up to the maximum A4 format) by the post office personnel. The cost of the post office service is about 33 kč per page. In case if you are able to leave the original documents to us, we can arrange legal copies from the post office.
Any document that has a photo sticked can't be legally copied. For example, passport, ID, or car certificates can't be legally copied. Documents in foreign languages can be legal copied without any translations to Czech.
Additionally, legal copies also can be arranged at any notary office.
