Last name didn't change after getting married.
I moved two sims in together and when they got married, the female still has the same last name she did before they got married, and their child has her last name.

Is changing the last name in CAS the only option?
So far it's the only one I know...Sadly to this day I still have to rename my simmers who are newly wedded in game. It's a bit of a pain sometimes.
