DOES your parents have... or DO your parents have ?

when someone refers to their parents or anyone else's parents, is "parents" considered singular or plural?

Does your parents have a pad in Mayorca?
Do your parents have a pad in Mayorca?

witch of them is the correct one?

and, is there any difference between BrEnglish and AEnglish in this specific case?

Thanks

"Do your parents," in both BE and AE.

Nothing irregular here: parent is singular, parents is plural.

Do your parents have a pad in Mayorca?

Note, the island is normally spelt "Mallorca" or "Majorca" in English.
