As we speak about Family Law, I want to begin my exposition with a concise picture of the Catalan society and the “Catalan family”. Our concept of family, like other neighboring societies, has changed substantially in relation to the preceding generations. Catalonia today is an aging society with rather low fertility, increasing divorce rates and a large increase in the number of single households (the result of an increased life expectancy). Furthermore, the man is no longer the only household member who contributes to household income; in more and more families both men and women engage in paid employment. The female employment rate has risen in a big way, which explains that the average age for a first marriage is over thirty years for both women and men. This fact means in practice that Catalonian couples have few children: one, two, or as a heroic common project, three.
