does usafrux have dominion of property after death of owner
The usufruct at civil law is simply a life estate which terminates at the death of the grantee, the property interest of which then reverts to the grantor.
Usufruct is the legal right to use and derive profit or benefit from property that belongs to another person, as long as the property is not damaged. You need to consult with an attorney in your jurisdiction to determine what the legal obligations are under your system of law.
As the naked owner, you have the legal right to visit your deceased father's house. However, with your stepmother having a usufruct, it means she possesses the right to use and enjoy the property during her lifetime. It's recommended to establish open communication and understanding with your stepmother to coordinate your visits to the house.
