Va. Code § 64.2-307
Until the surviving spouse's rights in the principal family residence have been determined and satisfied by an agreement between the parties or a final court decree, in cases (i) where the principal family residence passes under the provisions of § 64.2-200 and the decedent is survived by children or their descendants, one or more of whom are not children or their descendants of the surviving spouse, or (ii) where the surviving spouse claims an elective share in the decedent's augmented estate under this article, the surviving spouse may hold, occupy, and enjoy the principal family residence and curtilage without charge for rent, repairs, taxes, or insurance. If the surviving spouse is deprived of possession of the principal family residence and curtilage, upon the filing of a complaint for unlawful entry or detainer, he is entitled to recover possession of such residence and damages sustained by him by reason of such deprivation during the time he was so deprived. Nothing in this section shall be construed to impair the lien or delay the enforcement of such lien of the Commonwealth or any locality for the taxes assessed upon the property.
