Typically when speaking about power of attorney, people refer to what is known as general power of attorney. General power of attorney allows a person to act on our behalf in an unlimited scope until that power is revoked. That is not the only type that can be granted.
Specific Power of Attorney
Suppose you want your representative to only be able to write checks from a specific account, or only act on specific matters such as paying bills for a home; this would be specific power of attorney. Specific power of attorney imposes specific limits upon what a person can do for you. You can also specific the duration.
Multiple Power of Attorney
This allows you to appoint two (or more) representatives to work together to represent you. This means that both representatives are required to sign any documents, papers or checks in order to bind them to you. While this may seem like a good idea, it does require a willingness to work together between your parties. It also requires both parties to be available.
Alternate Power of Attorney
This allows you to have a line of successors who will gain your power of attorney should the current acting one be unable or unwilling to perform the job. Successors cannot act while the previous person is still holding power of attorney.
There are many other options available to you when choosing power of attorney that internet forms or “legal aid” sites may not explain clearly or at all. Talking to experts will help you to better know your options.
