La custodia compartida ha experimentado una expansión notable durante la última década en todo el ámbito occidental. De hecho, en muchos territorios ha triplicado su porcentaje entre las custodias otorgadas tras la ruptura de los padres. Esta tendencia ha venido acompañada de un intenso debate social, académico y legislativo de alcance interdisciplinar sobre la conveniencia de otorgar preferencia a este tipo de custodia. Es un viejo debate que ahora parece haber llegado a un punto crítico de bipolarización. En este artículo se estudian los distintos argumentos esgrimidos a favor y en contra de la prevalencia de la custodia compartida desde un doble prisma determinado por el principio del interés del menor y la violencia de género. Además, se analiza un nuevo debate que ha surgido recientemente sobre si la igualdad de género ha de ser el factor decisivo a la hora de tomar una decisión sobre la custodia compartida.

Study of shared parenting over the last decade: A global social and legal struggle on the brink of a new era

Shared parenting has undergone a remarkable evolution over the last decade. Its expansion has been remarkable at a global level throughout the West, and in many territories it has tripled its percentage in the total number of cases resolved after the break-up of the parents. This trend has been accompanied by an intense social, academic and legislative debate of interdisciplinary scope on the convenience of giving preference to this type of custody. It is a long-standing debate that now seems to have reached a critical point of bipolarisation. This article studies the different arguments put forward for and against the prevalence of shared custody from a double prism determined by the principle of the interests of the child and gender violence. It also analyses a new debate that has recently arisen as to whether gender equality should be the decisive factor in deciding on shared parenting.
