Launching a major new research project examining the principles of succession law in comparative perspective, this book discusses the formalities which the law imposes in order for a person to make a testamentary disposal of property. Among the questions considered are the following. How are wills made? What precisely are the rules - as to the signature of the testator, the use of witnesses, the need for a notary public or lawyer, and so on? Is there is a choice of will-type and, if so, which type is used most often and what are the advantages and disadvantages of each? How common is will-making or do most people die intestate? What happens if formalities are not observed? How can requirements of form be explained and justified? How did the law develop historically, what is the state of the law today, and what are the prospects for the future? The focus is on Europe, and on countries which have been influenced by the European experience. Thus in addition to giving a detailed treatment of the law in Austria, Belgium, England and Wales, France, Germany, Hungary, Italy, the Netherlands, Poland, and Spain, the book explores legal developments in Australia, New Zealand, the United States of America, and in some of the countries of Latin America with a particular emphasis on Brazil. It also includes chapters on two of the mixed jurisdictions - Scotland and South Africa - and on Islamic Law. The book opens with chapters on Roman law and on the early modern law in Europe, thus setting the historical scene as well as anticipating and complementing the accounts of national history which appear in subsequent chapters; and it concludes with an assessment of the overall development of the law in the countries surveyed, and with some wider reflections on the nature and purpose of testamentary formalities. -
Recopilación de trabajos de investigación sobre temas que giran en torno a la “responsabilidad jurídica”, cuyos autores por su preparación y experiencia aportan aspectos y matices prácticos sobre el tema o trabajo tratado. El nacimiento de la obligatio como vinculum iuris llevó aparejado la necesidad de apertura de un cauce priocesal especifico en el que se permitiera al iudex la condena a los que se debía dar o hacer (dare facere oportere) contenido en el acuerdo verbal de la sponsio. Mediante la legis actio iudis postulationem se produjo el nacimiento del concepto procesal de actio como derecho a perseguir en el juicio lo que nos es debido… -

La presente obra, aunque constituye un todo orgánico, tiene dos partes claramente diferenciadas: la primera parte es la teoría general de la sucesión y la segunda se subdivide a su vez en dos materias: la sucesión legítima, o sea aquella que se produce cuando no existe testamento, y la sucesión contractual dedicada a los pactos sucesorios. Todo ello se estudia no sólo bajo la óptica del Código Civil, sino también de las distintas legislaciones específicas #llamémoslas o no forales# que existen dentro de nuestro país; y que tan ricas son en algunas materias como éste, precisamente, de la sucesión paccionada, que el Código Civil la había ignorado totalmente (por lo menos hasta la reciente reforma del artículo 831) . Todas estas materias están claramente relacionadas no sólo por regular el hecho sucesorio, sino, también de manera negativa por no aludir a la sucesión testamentaria y dejar aparte la sucesión forzosa o legitimaria, hasta el punto de que incluso determinadas materias, como el derecho de representación, han sido encuadradas en uno u otro ámbito según los diversos autores que los han estudiado, y que han seguido un criterio racional o legal (atendiendo a la ubicación dada por el Código Civil). He tratado de actualizar a fecha de hoy #marzo 2007# la normativa y jurisprudencia existente sobre las diversas materias. -
