A power of attorney can be created for several different purposes. You might need a limited POA for the sale of property for which you are unable to be present, or a medical POA in which a health care agent is appointed who can make decisions for your care if you should become incapacitated. A lawyer can make sure you have covered all the bases when an attorney-in-fact has been named and the document is drawn up, because a power of attorney may not be met with universal approval, especially by certain family members.
