The power of attorney required an attorney to draft the document, so I found a very reputable bilingual attorney in Quito, who was referred to me. This required a minor fee, plus notary, which is not simple.
Then the will to be registered in Ecuador was more complex. The writing of the will was fairly simple as I simply took my will from the US, translated, and made more simple. This required several trips to the attorney and several to the notary.
I feel that I have done all due process in the event of my death or disability, or to sell my property when the value doubles.
