How is the title to the house currently held? Does your grant deed say one of the following: Your names, "husband and wife as community property, with right of survivorship" or your names, "as joint tenants with right of survivorship"?
Title companies and escrow companies are often asked to record grant deeds and quitclaims deeds as accommodations, where no title insurance policy is issued. The notation does not affect your rights or title. What matters is how the title is written, as discussed above.
