Northglenn, CO estate planning & probate attorney Jeff Althaus talks how long the probate process typically takes in CO. He explains that the probate process in Colorado is mandatory and lasts for a period of six months. While it may not sound particularly exciting, it is actually one of the quickest probate processes in the United States. It’s important to understand that when you own property in multiple states, you will need to go through each state’s probate process, which can extend the overall duration of the probate process in Colorado. For example, if you own property in California, Arizona, or even Iowa (my home state), the probate process will take longer. Six months is the minimum required duration, and on average, probate in Colorado typically takes between six months and a year to complete.
