What is the ruling on a wife waiving her ownership of a property registered in her name to her father without her husband's knowledge and consent, especially given that the husband bought the property with his own money and registered it in his wife's name due to his non-citizenship status, and he also covered her study and travel expenses? Does the husband have the right to demand the return of the property in exchange for reimbursing the amounts paid by the wife's father?

The husband's registration of the property in his wife's name does not grant her ownership of it; rather, it remains his property. The father or husband is not legally obligated to pay for his daughter's tuition fees; whoever pays them is considered a donor. Regarding what the father paid on behalf of his son-in-law in expenses and debts: if it was a donation, there is no compensation for it; but if he intended to reclaim it, he may do so with an oath if there was no witness. The property remains the husband's, and the wife's father may reclaim his debts from him under the aforementioned conditions.
