Use of "depuis" for an action that is presently continuing

Question

This was listed as the correct answer, but I had understood that, for actions that are continuing in the present, the present tense was used with "depuis." Did I miss something? Thanks.
Les Souillard sont mariés depuis plus de vingt ans." means:

The Souillards have been married for more than twenty years

Accepted Answer

Bonjour,
It may look like "Le Passé Composé" but, in fact, it's the verb "marier" in Le Présent in La voix Passive.
This question has been asked previously. Take a look here: linked question with passé composé correct?
I hope this is helpful.
Bonne journée !

Answer

I would just have said this was the present tense of être and mariés was an adjective. At least in English, it can only be a passive if we refer to the ceremony, e.g "we were married by the bishop".
