POAs are Easy to Get- Really Easy.

POAs are simple forms, and most lawyers have them. They are very easy for a lawyer to draft and modify, and they are very inexpensive. Most lawyers throw them in as a part of any basic will package (which is another topic- you need a will. Believe lawyers when they tell you this. Unless you're Daddy Warbucks, it's not all that difficult/expensive, either.

The main requirement for signing a POA is that you need to be "competent" to sign a legal document. You need to be 18. You also need to have sufficient mental "capacity" to understand what you're doing. This is a little bit more of a fuzzy area (no pun intended), especially if you're dealing with a client who...has their good days and their bad days. However, lawyers who do this sort of thing know when somebody is "with it" enough to sign one of these documents.

Bottom line, though, if you're healthy, of sound mind (don't listen to your spouse- you're probably of sound mind despite anything they say), and over 18, you are probably fine to have a POA drafted. And it's a good thing- there's not a moment to waste.
