Si tu mourais, qu'adviendrait-il de ta famille ?

This should be the conditional tense, and the conditional tense conjugation is spelled mourrais.

It is funny you should say that; since the sentence was originally as you suggested, but was corrected later on. :slightly_smiling_face:

I happen to agree with the correction. I was taught that in French you can’t have a conditional in the main clause of a conditional statement.

Oh I see. Thank-you, I didn’t know that rule.
