Is it obligatory for the girl's family to inform the suitor's family of any illnesses the girl suffers from if explicitly asked, and is withholding information about strabismus (walleye) and severe myopia considered deception, and what are the implications for the suitor if he wishes to annul the contract before consummation for this reason?

Defects in marriage are divided into two categories: defects that must be disclosed, and if they are not disclosed, the suitor has the option to annul the marriage; and defects that do not have to be disclosed initially, but if the suitor requests their disclosure, it is not permissible to conceal them, and he has the option to annul the marriage if he discovers them after the contract. So, if strabismus (crossed eyes) or weak eyesight is customarily considered a defect, then the husband has the option to annul the marriage, and half of the Mahr (dowry) is waived for him. If he annuls it before consummation, then no Mahr is due from him.
