Should the groom SAY the statement in the kesuba to his bride on the day the kesuba is being written?
the statement in the kesuba
On the day .... the bridegroom ... said to this [...] daughter of [...], “Be my wife according to the law of Moses and Israel. I will work honor, feed and support you in the custom of Jewish men, who work, honor, feed, and support their wives faithfully. I will give you the settlement of 200/100 silver zuzim, which is due you according to virgin/widow law, as well as your food, clothing, necessities of life, and conjugal needs, according to the universal custom.”...
From what I understand the custom is that he does not SAY this on the day the kesuba is written (I might be wrong).
(Maybe he says something like this before they get "engaged" (vort) but that is usually more than 7 days before.)
How can the witnesses sign it if part of it is not true?
(Even if you say the whole ketuba is written because of minhag, won't this invalidate the witnesses if they are the ones who will witness the keddushin too?)
And therefore, shouldn't the groom say the statement?
