MY DAUGHTER'S NAME IS ALEXIS. WHEN A PROPER NAME ENDS IN AN "S" HOW DO YOU WRITE IT WHEN YOU WANT TO SHOW POSSESSION.

IF I WANTED TO SAY : THIS IS ALEXIS'S PARTY. WOULD THAT BE CORRECT OR DO I JUST PUT AN APOSTROPHY AFTER THE " S ".

PLEASE HELP

THANK YOU
Alexis's is correct.

Do you wish you had thought of this problem when selecting a name for your child?

For plural names, and some singular names, which end in an s, add only an apostrophe. ALEXIS'

That "rule" is far from universal, and in fact, one that I do not follow.

I would write "Alexis's" and "James's" every single time. You're welcome to pick a style and stick with it, but don't tell people there is only one rule for it when both James's and James' as well as Alexis' and Alexis's are acceptable.
