Spain’s gambling law bars minors from lottery participation
Spain’s Law 13/2011 prohibits minors from participating in gambling, including the Christmas Lottery, the source material says. A prize ticket given to a child cannot be claimed by the child; an adult would have to collect it, and a later transfer of the money to the child would count as a donation subject to inheritance and gift tax.
Lottery sellers and operators must prevent minors from participating and explain the restriction to the public.
