yes, finish probate in Colorado. If it is like Texas, the judge will sign orders for you to have Letters Testamentary, and others essentially ordering you as the legal executor to transact business on behalf of the Estate. Those all need to go to the county clerk, along with a copy of your mom's will. Ask for returns from the counties after they are registered. Then you can file with the operators and give them the page and volume references. That should fix the problem
