Anyone who needs support measures can request them; and so can their closest environment, whether it be their spouse not separated in fact or legally or who is in a similar de facto situation, and their descendants, ascendants or siblings, as well as the Public Ministry.

Furthermore, any person may report to the Public Prosecutor's Office any facts that could determine a situation requiring the judicial adoption of support measures. And public authorities and officials who, by virtue of their positions, become aware of such facts concerning any person must also report them to the Public Prosecutor's Office.
