Hire a real estate attorney to prepare the proper legal documents (they will also nhave to be notarized),to include your wife as a co-owner of the property and make sure it is properly filed with the county clerks office. It should be relatively inexpensive.
Since you are not transferring ownership to your wife solely, but ADDING her to the ownership via deed, you do not file a Quit Claim deed. This type of deed transfers ownership of the property from you TO her.
<<A quitclaim deed is a term used to describe a document by which a person (the "grantor") disclaims any interest the grantor may have in a piece of real property and passes that claim to another person (the grantee. The most common use for a quitclaim deed is a divorce in which one party is granting the other full rights to, and eliminating any interest in, a property in which both parties held an interest. If a husband and wife own a home and divorce, and the wife acquires the home in the decree, the husband would enact a quitclaim deed to eliminate interest in the property. >>.
To add an additional named owner in a deed, you need to have someone prepare a new deed to be signed by the current owner (YOU), granting the property from the current owner (YOU) to you AND your wife. The attorney you hire to help do this will explain the different meanings of other words that can be used to describe the intent of your relationship (joint tenants, tenants by the entirety, joint tenants with right of survivorship, tenant for life estate, etc), as well as the risks in being named in the deed (tax liens, mortgages, premises liability, etc
Hope that helps.
