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.
I would call the Title Company and/or Attorney that did the closing and issued the Title Insurance Policy.
Just an FYI,
The deed must identify who is handing over an interest in the property (the grantor) and who is accepting it (the grantee). Most counties require the deed to have the addresses of all the parties involved. And a deed wouldn't be a deed without words of conveyance -- a passage that says that the grantor intends to convey an interest in the property to the grantee.
If I can be of any other assistance, don't hesitate to contact me.
Is it possible you received the wrong deed?
