The English formula is still standard in notarial attestations:
"Each of the undersigned, individually and severally being duly sworn, deposes and says:
The within Will was subscribed in our presence and sight at the end thereof by _____________________, the within-named Testator/Testatrix, on the ____ day of __________, 20 __, at ________________________[address].
Said Testator/Testatrix at the time of making such subscription declared the instrument so subscribed to be his/her Last Will and Testament.
Each of the undersigned thereupon signed his or her name as a witness at the end of said Will at the request of said Testator/Testatrix and in his/her presence and sight and in the presence and sight of each other."
