My father has passed away. He was the sole owner of a house where he lived with his wife. In his holographic will, he deprived her of her legal rights to the estate and gave her the usufruct of his movable property. Can she continue to live in the house?

Yes. Article 764 of the Civil Code provides for the benefit of the surviving spouse a right of habitation to the accommodation which he occupied as his principal residence at the time of death, and a right of use to the furniture within the latter. It can only be deprived of this by the deceased through the means of an authentic will (established by a notary). Failing this, this right is maintained.
