Acceptance is done by the final and unqualified approval of an offer, the acceptance of the precise terms of the offer without modification. A Memorandum of Understanding (Memorandum of Understanding) is a kind of agreement between two (bilateral) or more (multilateral) parties. It expresses an agreement of will between the parties and indicates a planned common course of action.  It is frequently used either in cases where the parties do not involve a legal obligation, or in situations where the parties are unable to enter into a legally binding agreement. It is a more formal alternative to a gentlemen`s agreement.   Whether there is a binding contract between the parties and, if so, what conditions depend on what they have agreed. Contracting parties are not obliged to agree on all the terms of a proposed contract before it can be binding. All essential conditions must be agreed upon and the agreement cannot otherwise be uncertain, vague or ambiguous. The first two elements can be combined. A contract is entered into when one party has made an offer accepted by another party. In international relations, moUs fall into the broad category of treaties and should be included in the United Nations Treaty Book.
 In practice and despite the insistence of the United Nations Ministry of Rights to submit registration to avoid “secret diplomacy”, MoUs are sometimes treated confidentially. Legally, the title of the agreement does not necessarily mean that the document is binding or non-binding under international law. In order to determine whether a given project should be a legally binding document (i.e. a treaty), it is necessary to examine the intention of the parties as well as the position of the signatories (for example. B Minister of Foreign Affairs versus Environment Minister). An in-depth analysis of the text will also clarify the exact nature of the document. The International Court of Justice has an overview of the determination of the legal status of a document in the pioneering case of Qatar/. Bahrain, 1 July 1994.  Do you know what you need to enter into a contract? You thought there was a contract, but the agreement was not binding? Did you enter into a binding contract thinking you wanted to reach another agreement? An offer can only form the basis of a binding contract if it contains the essential terms of the contract. As a minimum requirement for the sale of goods contracts, a valid offer must include at least 4 conditions: delivery date, price, payment terms that include the payment date and detailed description of the item offered, including a fair description of the condition or type of service.
If the minimum requirements are not met, an offer to purchase is not considered by the courts as a legal offer, but as an advertisement. Under Dutch law, in most cases, a complaint is more an invitation to make an offer than an offer.  Once the fundamental elements of offer, acceptance, reflection, intent to be legally bound and capacity exist, a number of legal consequences arise within the contractual relationship. A sales contract (SPA) is a binding legal agreement between two parties that binds a transaction between a buyer and a seller. SPAs are generally used for real estate transactions, but they are present in all industries. The agreement concludes the terms of sale and is the culmination of negotiations between buyer and seller. This could be called a “trade agreement.” There are no plans to be legally binding. These are communications that are part of the negotiations. The “legally binding” treaty is expected to arrive later.
As a rule of convenience, if the offer is accepted by mail, the contract is entered into at the time the acceptance has been reserved.  This rule applies only if the parties are implicitly or explicitly considered as means of acceptance.  It excludes contracts relating to land, misdirected letters and immediate modes of communication.
