Power of attorney – in many legal systems the Power of Attorney is considered as authorization document which gives a practicing lawyer the legal right to make binding decisions for their client. A power of attorney may be specific to a certain kind of decision or general, in which the lawyer makes all major decisions for the person who is the subject of the power of attorney. The person signing the power of attorney is usually referred to, in law, as the client and the person that would exercise the power of attorney, the lawyer, who has to protect their legal and financial interests. This specific type of protection is the reason why a person hires a lawyer. The term has to be separated than the term “letter of authorization” which consists of legal rights, given to proxy who is not a law practitioner and not a lawyer.
The power of attorney should be differed than the power of appointment, applicable in the Inheritance Law. There is huge difference between these two. The power of appointment should be used and performed after the death of the authorizer, while the power of attorney could be used by the representative only while the authorizer is still alive and in good mental health. The other difference is that via the power of attorney, the authorized person makes actions as if done personally by the authorizer.
Note that lawyers do not work (i.e. accept pressure by the opposite parties) for free; their personal advocacy is paid, so when asking a lawyer for their legal opinion on a concrete legal issue, you should pay them for their opinion and legal advice; it is the same like when you visit a doctor and pay for their competent diagnose and accurate medical treatment.
