If your husband has a will then his property is distributed accordingly, if he not have a will then the distribution of property is determined by a probate court.

When a husband who received property through a deed of gift dies, the treatment of that property depends on several factors, including the terms of the deed, state laws, and whether the property was jointly owned. If the deed specifies that the property is solely in the husband's name and there are no rights of survivorship, the property may pass to his heirs or be distributed according to his will. If the property was gifted to him as part of a joint ownership arrangement or with survivorship rights, it may automatically transfer to the surviving spouse. Additionally, any debts or claims against the estate could affect the distribution of the property.
