Gentlemen`s agreements, because they are informal and often not written, do not have the same legal and regulatory protection as a formal treaty and are therefore more difficult to enforce. A gentleman`s agreement, which is rather a point of honour and etiquette, relies on the indulgence of two or more parties for the performance of pronounced or unspoken undertakings. Unlike a binding contract or a legal agreement, there is no legal remedy for violation of a gentlemen`s agreement. A gentlemen`s agreement, or gentleman`s agreement, is an informal and legally non-binding agreement between two or more parties. It is usually oral, but it can be written or simply understood as part of a tacit agreement by convention or by mutually beneficial label. The essence of a gentlemen`s agreement is that it depends on the honour of the parties for its achievement, rather than being enforceable in one way or another. It differs from a legal agreement or a contract. In English contract law, for it to be binding, an agreement must have the intention of establishing legal relations; but in commercial transactions (i.e. agreements that do not exist between family members or friends), there is a legal presumption of “intent to establish legal relations”.
In the 1925 case of Rose and Frank Co. v. JR Crompton – Bros Ltd., however, the House of Lords found that the phrase ” “This regulation is not … a formal or legal agreement … is only a record of the parties` intention “was sufficient to rebut this presumption.  Man kan eksempelvis indga en mundtlig Gentlemen`s agreement om et udlén. Normally the neaftale indeholder bestemmelser og retsvirkninger, om hvad der vil ske, hvis l`net ikke tilbagebetales eller kompenseres. En gentlemen`s agreement afh`nger i stedet af parternes er, hvormed det ikke er en juridisk aftale.
Parterne stoler p` hinandens ord; in the net vil blive tilbagebetalt. In the worst case scenario, a gentlemen`s agreement can be entered into to practice anti-competitive practices such as pricing or trade quotas. Since a gentlemen`s agreement is tacit – which is not subject to the document as a binding legal treaty – it can be used to create and enforce illegal rules. A gentleman`s agreement, defined at the beginning of the 20th century as “an agreement between gentlemen who looks at price control,” has been described by one source as the most lax form of a “pool.”  Such agreements have been declared in all industrial sectors and are numerous in the steel and steel industry.  Gentlemen`s agreements can also be found in trade agreements and international relations.
