General power of attorney forms are useful for a wide range of purposes. They can be customized to specific scope of authority, length of time, and the third party.
A sample power of attorney form is attached that I use for individuals and small business clients.
Note that this is not a durable power of attorney. I published a sample durable power of attorney form on www.wealthmanagement.us.com.
Consult with an attorney if you are not completely comfortable with your understanding and use of these forms. I am not able to offer legal advice.
