The article discusses the issue of personal juridical acts that can not be concluded by an attorney. The work uses, above all, the formal-dogmatic method, as well as comparative and historical-legal method. According to art. 95 § 1 of the Civil Code, the possibility of acting through a proxy is subject to restrictions due to the act and the nature of legal transaction. The restrictions mentioned seem incomplete – they lack the inability to act through a proxy due to another legal act. In the author’s opinion, the nature of the legal transaction should be identi- fied with non-property legal transaction. The article categorized the divisions of personal legal transactions into personal primary and personal secondary as well as personal formally and materially.
