Custody is the legal term used to refer to the division of time that the child will spend with each parent after the family crisis.
It is one of the measures on which the court must necessarily rule by means of a judgment in contentious cases in which the parents have not reached an agreement regulating their personal relations.
Likewise, the Regulatory Agreement of separation, divorce or paternal-filial measures made by mutual agreement between the parents must necessarily regulate the custody of the children, as well as the maintenance and other measures.
Custody may be established jointly between both parents (shared custody) or it may be established in favour of one parent only, which gives the other parent visitation rights that must also be regulated.
Custody exercised by only one of the parents is called sole custody and can be maternal or paternal. The custody regime can be modified if this is expressly agreed or if there is a change in the circumstances that determined the choice of one or the other system.
Thus, the parent who is interested in the change of custody may initiate a judicial procedure called “modification of measures”, requesting that by means of a court ruling he/she be granted sole or shared custody of the children.
