This essay sheds light on what is the power of attorney, demystifies the different types of power of attorney that people can have, explicates the reasons why people grant other people power of attorney, and reveals the problems with granting other people power of attorney. The power of attorney refers a document which renders it permissible for another person to be able to act on your behalf. In other words, whenever you grant power of attorney to a person, then he has the authorization to act on your behalf. The power of attorney document confers another person with the authority to be able to implement decisions on your behalf in certain contexts. The scope of authority that a person has over your affairs will vary depending upon the type of power of attorney that you grant him. If a person is bestowed power of attorney, then he has been entrusted with the authorization to act on your behalf with the hope that he will implement decisions that are eminently aligned with your best interest. A person who has been granted power of attorney should never implement decisions that are unaligned with your best interest. If a person is bestowed power of attorney, then he should exhibit the utmost diligence and should be mindful of your best interest before implementing decisions on your behalf. If a person is bestowed power of attorney, then he should desist from blithely implementing imprudent decisions that are unaligned with your best interest. The power of attorney allows another person to be able to manage your affairs in certain contexts. The medical power of attorney, for instance, allows an agent to be able to implement decisions that are based on the medical doctor’s recommendations which appertain to the principal's medical matters. If a person is granted medical power of attorney, then the agent should choose the utmost optimal medical care decisions that are based on the medical doctor’s recommendations if these authorities have been granted to the agent by the principal in the medical power of attorney document. It is of eminent importance for a person who has been granted medical power of attorney to always be willing to implement optimal decisions that are aligned with the principal's best interest. A medical power of attorney can either be a durable medical power of attorney or a non-durable medical power of attorney. When a person is granted power of attorney, he then becomes the agent of the principal and is entrusted by the principal to implement decisions in the principal’s best interest that are optimal decisions and are not abysmal decisions. If a general power of attorney is granted to a person, then the agent of the principal, for instance, will be able to implement decisions regarding the principal’s financial matters, medical matters, business matters, and estate matters. Even though the power of attorney can be granted to more than one person, it is typically granted by the principal to a single person in lieu of multiple people when it is granted. A principal will grant a person power of attorney in contexts in which he would prefer for an agent to handle his affairs. If a principal grants a person general power of attorney, the agent will then be at liberty to implement decisions regarding the principal's financial matters, medical matters, business matters, and estate matters which can allay the onerous burden of managing his affairs on the principal’s end if an agent is able to act on the principal’s behalf and is always willing to implement astute decisions that are aligned with the principal’s best interest. There are complexities involved in implementing decisions that appertain to another person’s financial matters, medical matters, business matters, and estate matters. Having an agent act on your behalf who is always willing to implement astute decisions that are aligned with your best interest renders it less cumbersome for you to be able to manage your affairs. Having an agent act on your behalf who is always willing to implement astute decisions that are aligned with your best interest can also render it significantly less stressful for you to be able to manage your affairs. Managing one’s own affairs is an onerous burden that not every person is content with perpetually dealing with by themselves. If a principal is amenable to granting a person power of attorney, then he should only possibly consider doing so if the agent is always willing to implement astute decisions that are aligned with the principal’s best interest.
