1. This is Alice and Bob's house.
2. This is Alice and Bobs' house.
3. This is Alice's and Bob's house.
I would never say the third one out loud.
Presumably number 1, "This is (Alice and Bob)'s house", where Alice and Bob are a plural unit, like the children in "This is (the children)'s house". Am I right?
I would like to check because I don't remember ever having seen this in an English grammar.
