Abstract
The article examines linguistic errors in legal texts that violate applicable linguistic norms regarding the naming of countries. The study addresses this issue because of the considerable number of toponymic errors found in legal and lawyers’ language and because, given the distinctive function of such texts, these errors may have extra-linguistic consequences, including the creation of legally ineffective provisions and difficulties in the application of the law. The research is based primarily on quantitative corpus analysis, complemented by qualitative concordance analysis. The exploratory survey identified 14 texts of the law and as many as 1,841 lawyers’ texts containing non-standard toponyms. In addition, the article discusses the potential consequences of lexical errors in texts that have the performative function and considers possible approaches to their interpretation.
