Probably not. Usually, what's most important is the substance of the deed: the description of the property being transferred and the names of the old and new owners. Here's a brief rundown of the most common types of deeds:
A quitclaim deed transfers whatever ownership interest you have in the property. It makes no guarantees about the extent of your interest. Quitclaim deeds are commonly used by divorcing couples; one spouse signs all his rights in the couple's real estate over to the other. This can be especially useful if it isn't clear how much of an interest, if any, one spouse has in property that's held in another spouse's name.
A grant deed transfers your ownership and implies certain promises -- that the title hasn't already been transferred to someone else or been encumbered, except as set out in the deed. This is the most commonly used kind of deed, in most states.
A warranty deed transfers your ownership and explicitly promises the buyer that you have good title to the property. It may make other promises as well, to address particular problems with the transaction.
