If you have the latest original will, you do not have to locate his attorney. However, it would be wise to check with his attorney to see if you have the latest will. If you wish to find out if his attorney is active, retired, or even alive, you can go to the Colorado Supreme Court website and see if his attorney is registered and get the attorney's address and contact information.
The latest original will needs to filed with the probate court in the county where your father lived at the time of his death.
You may or may not need an attorney to assist you in handling his estate. That depends upon your father's property, the will, and any special issues arising from his bills. Many attorneys, including myself, offer a free initial consultation that can point you in the right direction and determine whether you need an attorney to assist you.
As Mr. Valentine said, you don't need to worry about tracking down his attorney. Most wills are fairly straight forward in terms of distribution of assets, and many estate plans were done years ago, so the attorney may have moved, retired, etc. I offer a free consultation and work with people across Colorado in probate matters, including in El Paso County. I definitely can point you in the right direction (and you need to follow very specific procedures with creditors that we can discuss) and then you can decide if you would like legal assistance with the process - I do most probate work on a flat fee basis and the estate pays the attorney fees. I hope this helps.
