How do you write sworn to before me?

I don't quite understand your question, but if you are talking about a jurat, i.e. a certification by a notary public or other official that an oath was administered and a document was signed in the official's presence, the proper verbage is:

STATE OF ______________
COUNTY OF _________________

Sworn to and subscribed before me this ______ day of ______________, 20____, by ___(name of person signing document/swearing)_____, who ( ) is personally known to me, or ( ) has produced ____________________ as identification.

(SIGNED) ________________________
NOTARY PUBLIC
(or other official authorized to administer oath)
