My father told me that I would have nothing at his death because he was going to make me recognize as unworthy of his succession. Can it?

Indeed, an heir who is deemed unworthy may be excluded from an estate. However, the law strictly controls the assumptions of unworthiness. All have in common a serious fault of the heir with respect to the deceased . It is not your father who can make you recognize as unworthy, but the law or the court at the request of another heir.

- Legal cases
The heir is automatically excluded from the estate if he has been sentenced to criminal punishment as an author or accomplice:
- a murder or attempted murder of the deceased,
- beatings, violence, assault causing the death of the deceased without intent to give it

- Court cases
After the opening of the succession and at the request of another heir, the court of first instance may pronounce the unworthiness of an heir. Example: in case of conviction for false testimony against the deceased in criminal proceedings.

Namely: the person excluded from the estate can inherit if the deceased, during his lifetime, expressed it in his will .
