Act No. 500/2004 Coll., the Code of Administrative Procedure, declares the Czech language as the language of use in administrative communication, while a participant in an administrative procedure may also use the Slovak language in spoken and written communication. Citizens of the Czech Republic who belong to a recognised ethnic minority may also use the language of their minority in spoken and written communication. Anyone who claims to have an insufficient command of the language in which the procedure is taking place has the right to an interpreter. In an application procedure, an applicant who is not a citizen of the Czech Republic shall procure a translator at his or her own expense, unless the law states otherwise. The same procedure applies in other legislation, including, for example, the Criminal Code.
There is no law regulating the use of language in the field of culture in the Czech Republic.
