Attorneys do argue whether or not a quit claim deed IS a deed of conveyance at all. The language of a quit claim deed generally would not contain the words "grant" or "convey" which are the operative words in the transfer of real estate. A quit claim deed is more about quitting or releasing rights to another party and is more appropriately used when the party receiving the rights already has ownership and is simply acquiring missing pieces or tying up loose ends.
A warranty deed on the other hand, whether general or special, clearly conveys ownership and includes some promise of defense of title by the seller. This warranty given by the seller shouldn't be pooh poohed as it may cover some things your title insurance does not cover. So, buying real estate with title insurance but without a warranty deed from the seller is a more risky proposition.
Now, you have the issue of whether or not you can even GET title insurance when the seller is giving you a quit claim deed. Most title insurers will flinch at the prospect and may refuse to insure.
Back to your query, I would have to say that IF you can get title insurance over a quit claim deed, only YOU can decide if it is OKAY.
