In Colorado what happens to your home if you die and your spouse is an owner by a Quitclaim Deed but is not named on the General Warranty Deed?

Assuming that one party acquired the land by virtue of a warranty deed and then conveyed it to himself or herself and spouse by a quitclaim deed, that would be effective as long as the deed was drafted properly. You need to check the tenancy created in the most recent deed. If it is a joint tenancy and one owner dies the survivor owns the property automatically.

Deeds should always be drafted by a professional. Errors made by non-professionals can be costly to correct if they can be corrected.
