Your agent would be best served by contacting a California attorney or the California Department of Real Estate (CDRE), which is equivalent to the Texas Real Estate Commission (TREC) in our state. Each state is responsible for determining the permissibility of an out-of-state agent listing a property for sale. Under Texas law, a person acting under the authority of a will or a written trust instrument does not have to obtain a Texas real estate license in order to sell real property in Texas. Unfortunately, Texas law means nothing in California.
