We've had a lot of questions regarding the PI licensing in Colorado as of late and we are just as confused as you so here is what we've found out:
The Governor did veto the bill to continue licensing BUT our regulatory agency DORA released their FAQ sheet on their website the other day and stated that the program is in a 'wind up' timeline.

The program will continue as it has for the last 5 years until May 31, 2021 or longer. DORA states this will require ANYONE operating as a PI in Colorado to continue to be licensed. Retain your license if you were previously licensed and obtain your license if you are offering Investigative services in Colorado. You will need to retain your $10,000 bond as well until they decide the program is done. They will also still take complaints so Investigators can still lose their licenses during this time period. The original FAQ can be found on the DORA site at dpo.colorado.gov/PrivateInvestigator in the News Items. But here it is for you:
