A lien (pledging of immovable property) was a very often used institute in the medieval period. The researched cartulary of loca credibilia recognized two basic forms of lien - vadimonium (lien with the property transfer) and antichresis (lien with a right to use). In the law of the nobility (law of the Kingdom), the lien was a part of the special character of rights in rem, limited by the both system of donations and the system of inalienable inheritance (aviticitas). The basic piece of writing of the medieval Hungarian law, Opus Tripartitum, treated the relatively detailed regulation of lien under the heading of impignoratio. A change in the evolution of lien in Hungary goes hand in hand with the emergence of modern legal thought influenced by the natural law codification efforts, the need to revive the country´s economy and with the development of contact relations and their securing (in case of lien, the antichresis was replaced by mortgage/hypothec).
