Coronavirus and delivering a baby

There’s been lots of talk about those who will be delivering babies in the next few months that are worried they’re gonna have to deliver alone at the hospital with no visitors and the father not being able to be there.

My question is, if that actually happens, how will they go about the dad signing the birth certificate? Isn’t that usually done in the hospital after the baby is born?

It’s definitely really the least of our concerns in a time like this but I’m just genuinely curious how that would work lol.
