I will use my fiance's name socially, but I don't plan on legally changing anything. Socially I'll be Aimee mylastname hislasthame.
I absolutely plan to practice law under my maiden name (much to my FMIL's disappointment, I'm sure

). There are lots of attorneys in my family with this name, and it only seems right to carry it on. Plus, my father is deceased, and I'd like to keep his name as a part of me.
