Power of attorney is a special legal designation that authorizes someone to act on your behalf in insurance, financial, personal, or legal matters. If you are deployed, you may want to consider assigning power of attorney to a spouse, family member, or trusted friend. To assign power of attorney, you and the individual you designate must sign a form before a notary public. Ask your base personnel office about where to find a notary. You may also consult the business listings in your local telephone directory to find notaries in your area.
