He would have had to have been there

Question

Hello,

have would one translate a sentence like this:

He would have had to have been there? The "tener que" thing has me confused about how to go about forming such a sentence.

Answer 1

habría tenido que haber estado ahi, but that is not correct.

he would have had to be there seems more like it. Habría tenido que estar ahí.

But can I say "habría tenido que haberlo sabido" - Zachary-Santamaria, Dec 4, 2010

no. - mediterrunio, Dec 4, 2010

Then, how would one say, "He would have had to have known it," medi? Just curious. - webdunce, Dec 4, 2010

Answer 2

Also :

Tenía que haber estado ahí.

I think it´s ¨Tendría que haber estado ahí¨ - mediterrunio, Dec 4, 2010
