Is an father entitled to evict his son from the home and disinherit him after the son marries a woman who is older than him, addicted, and undergoing addiction treatment, especially given the father's knowledge that the son cannot support himself?

If a marriage contract fulfills its conditions and pillars, it is valid even if the the parents are unaware, though it is recommended to inform them out of filial piety. If the son marries without their knowledge and they later find out, they should not demand a divorce unless there is a valid reason, such as the wife's weak religiosity or poor character and reputation; in such a case, the son must obey them. However, if the son refuses to divorce, the father is not permitted to disown him or deprive him of support or inheritance, as this would increase estrangement and animosity. The father should exercise patience and forbearance and try to reconcile his son and his wife with gentleness and wisdom.
