evidence: Before the birth or adoption of a first child, married parents may choose the child's surname (mother's or father's but not both). If no choice is made, the child automatically bears the father's surname. Any further children will also go by this name. If the parents are not married, the children will automatically have their mother's name unless otherwise indicated.[57] [...] Law 11/1981 in Spain, enacted in 1981, declared among other things that children, on turning 18, now had a legal option to choose whether their father's or mother's surname came first. If a family did not exercise an option to change the order of the names in their surname, the law defaulted to the father's surname as the first.[60] Also in Spain, a 1995 reform in the law allows the parents to choose whether the father's or the mother's surname goes first, although this order must be the same for all their children. For instance, the name of the son of the couple in the example above could be "Andrés Gómez Reyes" or "Andrés Reyes Gómez".[61]
