We have two possibilities when mentioning who has what:
Hay dos posibilidades para decir que alguien tiene algo:
1) Possessive adjectives - Adjetivos posesivos
There is one possessive adjective for each subject pronoun. Watch out! The possessive adjective to be used depends on who has what not on the number of things this person has. Example: my book = my books
Existe un adjetivo posesivo por persona. Atención, depende del poseedor no del número de cosas que se poseen. En español, mi libro – mis libros
When you have a list of things belonging to the same person, you should only used one possessive adjective.
Cuando tienes una lista de cosas que pertenecen a la misma persona, sólo se usa un adjetivo posesivo.
Example: his brother and sister, my mother and father, our chairs, tables and books.
