Special warranty deed- What it means is the grantor does not warrant against title defects arising from conditions that existed BEFORE he owned the property. In some states, the special warranty deed is not as protective of the buyer as the general warranty deed. The special warranty deed says:
1. Grantor warrants that they have received title
2. Grantor warrants, unless specifically noted in the deed, that the property was not encumbered during THEIR period of ownership.
In effect, it only warrants the title against THEIR OWN actions or omissions. They warrant nothing PRIOR to their taking title.
