@Pono Wright The important thing to understand about the transfer of property is that the deed itself is only as good as the legal interest of the person giving it. A deed in and of itself does not create the interest held by the person giving it. So, if the grantor puts an interest in the deed, like mineral interests, it only conveys if they actually have them. Deeds are not like a car title. They are like a chain. Once a link is broken, it is a smaller chain with less rights.
The message from the title company is confusing. I can not imagine the seller wants to sign a deed conveying mineral rights just because the title company wants to "accommodate" you. If the seller has told you they own the mineral rights and is willing to sign a warrantee deed then they are responsible for defending that claim. If it is a quit claim deed, you are on your own. However, if it is important to you in this deal to get the mineral interests then you need to have someone run the title search for the mineral interest and get title insurance on that portion. Someone out there is doing them in your area and this title company should know who. If not, I would question their competency.
@Deborah Burian you are right- it is very common for people who still own the mineral interests to list it in a transfer as it is a big deal in Oklahoma. I had a bankruptcy client with one of those small interests (from an inheritance) take it into the bankruptcy with a value of $40 based on what someone had offered them. The trustee took it and sold it for $5000. So hold out hope! I personally don't bother with it on the deeds I create when I am paying $10,000 for a house out here in Shawnee and Seminole. Doesn't mean I don't get the interest if the seller has it. It's just they probably don't have it and it is not worth the cost/time to research it.
Sorry for the book- Bottom line- the deed you get is not what determines the previous owner's interest (they just created that document!). It does determine your interest. All you can get is 1. what they have AND 2. what they convey to you. When in doubt get an attorney or title insurance involved.
