The aim of the paper is to recall and analyse the main principles and specific solutions of the legi-slative draft formed by the „Problem Team for legal capacity of mentally disabled persons”. The Te-am operated within the Commission for the Codification of Civil Law in Poland and the Draft con-cerned the introduction into the Polish legal system of a new institution - equivalent to the German Vorsorgevollmacht or the English Lasting power of attorney. Using the method of critical analysis, enriched with comparative, international and systemic legal components, the author discusses six selected key-issues of the Polish version of the Lasting power of attorney, i.e. the reasons for the incapacity to make decisions, the scope of decisions, the durability of the state of incapacity to ma-ke decisions, the person of the proxy, the moment when the authority arose, and the scope and termination of the authority. Comments made are both approving and pointing to certain risks of adopting some of the solutions.
