Is it permissible for a mother to register the apartment she owns in the name of her minor son, fearing that the father might seize it and evict him after her death, especially since the father does not support them or spend on them?

The default is that a person is permitted to dispose of their property through gifts, charity, and similar acts. However, the intention behind such disposal must not be to disinherit heirs. Registering a house in a son's name so that he can acquire it after death, without transferring ownership to him during life, is not valid, because it constitutes a bequest to an heir. Such a bequest is not enforceable unless the other heirs approve it, due to the Prophet's (peace be upon him) saying: "Indeed, Allah has given every rightful person their right, so there is no bequest for an heir." We also point out that the wife's maintenance is incumbent upon her husband, and the father is responsible for the maintenance of his young child who has no wealth, and neglecting maintenance is a sin.
