Is the father obligated to inform the suitor about his daughter's scoliosis, even though doctors have confirmed that it does not prevent her from fulfilling her marital duties, and despite the daughter's desire not to inform him before the engagement is agreed upon?

Scholars have differed concerning the defects that necessitate the annulment of marriage. The preponderant opinion is that any defect that repels the other spouse and prevents the fulfillment of the purpose of marriage necessitates the option (of annulment) and must be disclosed. This includes a noticeable curvature that might cause aversion, affect social functions, or require surgical intervention. Disclosure is further emphasized if the curvature is progressive. As for a slight curvature that is not repulsive and does not affect one's life, it does not necessitate disclosure, although mentioning it is closer to trustworthiness and good counsel. Only the suitor must be informed, and there is no objection to delaying the disclosure until the suitor becomes acquainted with the virtues of the one being sought in marriage.
