General Versus Limited Powers
The power of attorney you grant to your agent may be general, which gives the agent a wide range of powers, or limited, granting only one or a few specific powers. Your bank may require a limited power of attorney that directly addresses your agent’s authority to access your accounts rather than a more general power of attorney. In addition, your bank may refuse to accept your power of attorney altogether, and some banks prefer that you use their power of attorney forms.
Your agent has a fiduciary duty, which means he must act on your behalf in all matters designated in the power of attorney document. He must put your interests above his own. You can sue the agent if he violates this duty, and he can be held criminally liable if he steals from you.
An agent acting under a power of attorney is merely your representative. A power of attorney does not give the agent ownership rights over any of your property, including bank accounts. Your agent is prohibited from using the money in your accounts for his own purposes. However, your agent may be entitled to reimbursement for necessary expenses incurred while acting on your behalf under the terms of the power of attorney.
An agent does not need to add his name to your account or otherwise create a joint account to act under a power of attorney, although you can authorize him to do so. A joint account gives both individuals named on the account – for example, you and your agent – ownership rights over the money in the account. Each joint owner can use the money in any manner desired, and when one owner dies, the other can gain full ownership of the account, regardless of what the deceased owner’s will might declare. If your agent creates a joint account, it can raise serious issues because he would be acting under a power of attorney but would also have ownership rights to the money in the account.
