In the context of sharing agreements, an agreement is often used to define the expectations and responsibilities of the various parties. These MOUs generally deal with issues such as: (1) liability for maintenance and repair costs, (2) insurance and liability, (3) staff and communication, and (4) conflict resolution. Whether the terms of these agreements are legally enforceable, as a final contract, depends on the intent of the parties. Therefore, the parties to a sharing agreement should consider in due course the legal status of their agreement as part of the negotiation process. While it is rare to see soft things in the multilateral field, transnational air agreements are in fact soft. Whether a document is a binding contract depends only on whether the document`s actual text (the „four corners”) contains clearly defined legal elements. The required elements are: offer and acceptance, consideration and intention to be legally bound (animus contrahendi).  In the United States, details may vary slightly depending on whether the contract applies to goods (under the single code of commerce) or services under the common law of the state.

This term is often used in the context of decentralization, for example. B in the 1999 concorda between the Central Ministry of Environment, Food and Rural Affairs and the Scottish Environment Directorate. There may be legal distinctions between the MOU and the MOA, there can be no legal or practical difference if they are written in a similar language. The key is whether the parties have attempted to be legally bound by the terms of the agreement or the contract. If that is the case, they have probably created a legally enforceable contract or agreement, whether they designate it as a contract or agreement. The parties must intend to create a legally enforceable agreement, but they do not have to intend to create – or even understand – that they enter into a „contract.” The essential part of the contact is (1) Parties (2) Legal Offer or Proposal (3) Legitimate Acceptance, (4) Promise, (5) Legal and Legally Applicable Consideration. 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.
