Where can I get a Durable Power of Attorney & Medical Power of Attorney form in the Greeley area?

Adding to FF's comments, there's a very good reason to use an attorney. With downloaded or boiler plate forms, you have absolutely no idea when they were last updated or revised, and whether or not they conform to current legal requirements in your state. Nor do you have the opportunity to discuss with someone who is credentialed the issues of particular concern for your situation.

I would use a lawyer. Its more on the up and up. The person initiating the POA should be present and of sound mind. If not of sound mind then they are not able to assign POA. Guardianship is needed then.
I insurance company requested that I update my POA. They wanted a letter from a lawyer saying the POA was still viable.

Flowrandy, without knowing your particular circumstances, it's impossible for me to advise whether you should hire an attorney to create a health care or financial, limited or comprehensive, springing or immediate, POA or DPOA, or to create one yourself using a template, or, instead to seek guardianship and/or conservatorship. If you have or anticipate complexities due to family disharmony, then contacting an elder-law attorney is most likely advisable. However, I can also say that perfectly good and usable POAs and DPOAs can be created by reasonably careful laypersons using standard forms available on-line, or at libraries, banks, nursing homes, hospitals, etc. When I did an on-line search for "Colorado power of attorney form," the following trusted website from the Colorado Bar Association was one of the results. It should help you decide what what type of POA authority you need and whether you to use the included form, or modify it for your specific need, or hire an attorney to write one for you.

Flowrandy, best to contact an "Elder Law Attorney" if you live in the States, and have the Attorney draw up the Power of Attorney as per your State Laws.

I know one can print off blank forms off the Internet, but all it takes is one wrong word or one misplaced word to create major difficulties with the forms.
