Agency (law) in the context of "Practice of law"

In commercial law, a principal is a person, legal or natural, who authorizes an agent to act to create one or more legal relationships with a third party. This branch of law is called agency and relies on the common law proposition qui facit per alium, facit per se (from Latin: "he who acts through another, acts personally").

It is a parallel concept to vicarious liability (in which one person is held liable for the acts or omissions of another) in criminal law or torts.

Vicarious liability is a form of a strict, secondary liability that arises under the common law doctrine of agency, respondeat superior, the responsibility of the superior for the acts of their subordinate or, in a broader sense, the responsibility of any third party that had the "right, ability, or duty to control" the activities of a violator. It can be distinguished from contributory liability, another form of secondary liability, which is rooted in the tort theory of enterprise liability because, unlike contributory infringement, knowledge is not an element of vicarious liability. The law has developed the view that some relationships by their nature require the person who engages others to accept responsibility for the wrongdoing of those others. The most important such relationship for practical purposes is that of employer and employee.

In contract law, an indemnity is a contractual obligation of one party (the indemnitor) to compensate the loss incurred by another party (the indemnitee) due to the relevant acts of the indemnitor or any other party. The duty to indemnify is usually, but not always, coextensive with the contractual duty to "hold harmless" or "save harmless". In contrast, a "guarantee" is an obligation of one party (the guarantor) to another party to perform the promise of a relevant other party if that other party defaults.

Indemnities form the basis of many insurance contracts; for example, a car owner may purchase different kinds of insurance as an indemnity for various kinds of loss arising from operation of the car, such as damage to the car itself, or medical expenses following an accident. In an agency context, a principal may be obligated to indemnify their agent for liabilities incurred while carrying out responsibilities under the relationship. While the events giving rise to an indemnity may be specified by contract, the actions that must be taken to compensate the injured party are largely unpredictable, and the maximum compensation is often expressly limited.

A power of attorney (POA) or letter of attorney is a written authorization to represent or act on another's behalf in private affairs (which may be financial or regarding health and welfare), business, or some other legal matter. The person authorizing the other to act is the principal, grantor, or donor (of the power). The one authorized to act is the agent, attorney, or in some common law jurisdictions, the attorney-in-fact.

Formerly, the term "power" referred to an instrument signed under seal while a "letter" was an instrument under hand, meaning that it was simply signed by the parties, but today a power of attorney does not need to be signed under seal. Some jurisdictions require that powers of attorney be notarized or witnessed, but others will enforce a power of attorney as long as it is signed by the grantor.

Disintermediation is the removal of intermediaries in economics from a supply chain, or "cutting out the middlemen" in connection with a transaction or a series of transactions. Instead of going through traditional distribution channels, which had some type of intermediary (such as a distributor, wholesaler, broker, or agent), companies deal with customers directly and vice versa, for example via the Internet.

In law, countersignature refers to a second signature onto a document. For example, a contract or other official document signed by the representative of a company may be countersigned by their supervisor to verify the authority of the representative. Also, a money order or other financial instrument may be signed once upon receipt, then signed again by the same person when presented for payment, as an indication that the bearer is the same person who originally received the item, and not a thief who has stolen the item before it could be carried to the place where it was to be presented.

An example in which a countersignature is needed is with British passport applications.

Entertainment law, also known as media law, encompasses legal services provided to the entertainment industry. These services often overlap with intellectual property law, which includes key components such as trademarks, copyright, and the right of publicity. However, the practice of entertainment law frequently extends into other legal areas including employment law, contract law, torts, labor law, bankruptcy law, immigration, securities law, security interests, agency, right of privacy, defamation, advertising, criminal law, tax law, International law (especially private international law), and insurance law.

Much of the work of an entertainment law practice is transaction based, i.e., drafting contracts, negotiation and mediation. Some situations may lead to litigation or arbitration.
