If you exclude the spouse with the DUI from your policy your insurance would not cover that person if they were involved in an incident in your car. If you are concerned about liability for his driving habits, a better way would be to obtain legal advice as to car ownership with him and to act on that.
A major violation such as a DUI can affect your insurance rate up to 5 years for some insurance carriers. Lighter guidelines can be found with a few insurance carriers, but a preferred rate probably won't be available until 5 years have passed. A major violation usually comes with an extra requirement from the state.
