According to the Virginia Code § 64.2-101, if a person dies without a will (intestate), their estate passes to their children or their descendants. If a child of the deceased person is deceased, their share of the estate passes to their children (the grandchildren of the deceased person).

If a person does not have any surviving children or descendants, their estate passes to their parents. If neither parent is alive, the estate passes to the person's siblings or their descendants. If a sibling of the deceased person is deceased, their share of the estate passes to their children (the nieces or nephews of the deceased person).

If a person does not have any surviving children, descendants, parents, siblings, or descendants of siblings, their estate passes to their nearest living relatives, according to the rules of descent and distribution set forth in Virginia Code § 64.2-101 et seq.

In your case, since you are the only surviving child of your mother and you have an adult daughter, your daughter would be the heir to your mother's estate under Virginia law.
