A person who has died cannot sign a deed, so the next step depends on how the property was titled.
If spouses owned it as tenants by the entirety, or co‑owners held it as joint tenants with right of survivorship, the survivor already owns the whole property. The usual step is to record a certified copy of the death certificate in the county records, often with an affidavit. Title companies may ask for more.
If the owner signed a lady bird deed, title passes to the named beneficiaries at death without probate. Those beneficiaries generally record the death certificate as well. See what to do with a lady bird deed after death.
If the deceased owned the property alone or as a tenant in common, their share usually passes through probate or a court order. Homestead property has extra rules about who can inherit it.
Once the deceased owner's name is cleared, the surviving owner may want a new deed, such as a lady bird deed, so the property passes smoothly at their own death.
