Salam alaykom,

I would like to know if it is possible for me and my wife to have sex while we just announced our paper marriage ( ketabit el ketaab-only) not the full marriage and if we did so what is the kafarrahh for this ?
Hope that you understood my question .
Thanks

You must wait until after the wedding ceremony to consummate the marriage but if you had already engaged in conjugal relations, it is not considered adultery [zina]. However, marital rights before and after the consummation of marriage differ; you are not entitled to ask for any of these rights before their time. Your wife is entitled to refuse your demands to consummate the marriage before the wedding ceremony.

It is a legal requirement to follow customs which serve to preserve rights. Honor the date that you agreed upon for the marriage ceremony with her guardian or ask him to move the wedding date forward if possible.
