In order for a contract to be concluded, the parties must be subject to mutual consent (also known as the Assembly of Spirits). This result is usually achieved by the offer and acceptance that does not change the terms of the offer, which is known as the “reflection rule.” An offer is a definitive statement about the supplier`s willingness to be bound if certain conditions are met.  If an alleged acceptance alters the terms of an offer, it is not an acceptance, but a counter-offer and, therefore, a rejection of the original offer. The single trade code has the rule of item 2-207, although the UCC only regulates goods transactions in the United States. Since a court cannot read the minds, the intention of the parties is objectively interpreted from the point of view of a reasonable person, as found in the first English case Smith v. Hughes . It is important to note that if an offer indicates a particular type of acceptance, only an acceptance communicated by that method is valid.  A concept of English common law that must be taken into account for simple contracts, but not for special contracts (contracts by thieves). The court of Currie v Misa  declared the idea of “right, interest, profits, benefits or leniency, damage, loss, liability”. That is why reflection is a promise of something precious given by a pare-all in exchange for something precious that is made by a promise; and in general, the thing of value is goods, money or stock.
Evidence of action, such as an adult who promises to give up smoking, is only enforceable if a legal right is waived.    For example, you suggest letting your friends stay in your home while they are in town. It is an agreement because there is no consideration exchange for the use of your home, and there are no conditions that have been written to comply with them. Your friends can`t sue you if you change your mind and charge them for a hotel. In some U.S. states, e-mail exchanges have become binding contracts. In 2016, the New York courts ruled that the principles of real estate contracts applied to both electronic communications and electronic signatures, provided that “their content and subscription meet all applicable status requirements” and in accordance with the Electronic Signatures and Records Act (ESRA).   In England, some contracts (insurance and partnerships) require the utmost good faith, while others may require good faith (work contracts and agency).
Most English treaties do not need good faith, provided the law is respected. However, there is a global concept of “legitimate trust.” An agreement is an agreement between two or more parties. A contract is a particular type of agreement which, by its terms and elements, is legally binding and enforceable in court. It is advisable (if possible) to ensure that your business agreements are available in writing in order to avoid any problems when trying to prove a contract. Oral agreements are based on the good faith of all parties and can be difficult to prove. In a less technical sense, however, a condition is a generic term and a guarantee is a promise.  Not all contractual languages are defined as a contractual clause. Representations, which are often pretracted, are generally less strict than terms, and material misrepresentations have historically been one of the reasons for the intrusion.
