A contract is a legally binding document between at least two parties, which defines and regulates the rights and obligations of the parties to an agreement.  A contract is legally enforceable because it complies with the requirements and approval of the law. A contract usually involves the exchange of goods, services, money or promises from one of them. „breach of contract“ means that the law must grant the victim either access to remedies, such as damages, or annulment.  Each country recognized by private international law has its own national legal system governing contracts. While contract law systems may have similarities, they can differ significantly. As a result, many contracts contain a choice of law clause and a jurisdiction clause. These provisions define the laws of the contracting country and the country or other forum in which disputes are settled. Without explicit agreement on such issues in the treaty itself, countries have rules for determining treaty law and jurisdiction over litigation. For example, European Member States apply Article 4 of the Rome I Regulation to decide on the law applicable to the Treaty and the Brussels I regulation on competence. This self-assessment questionnaire (SAS) focuses on migration management and prevention of speech in older adults with dementia in long-term care centres and also offers reflections for other environments. Because migration management and speech prevention strategies vary depending on the organizational factors and individual needs of people with dementia, this SAQ proposes important proposals; it is not exhaustive. Not all agreements are necessarily contractual, as the parties are generally considered to be legally bound.
A „gentlemen`s agreement“ should not be legally applicable and „compulsory only in honour.“   Little research has studied walking beyond the walls of the institution or residence. Therefore, no one really knows the full extent of the migration problem. Most scientific studies have studied only the percentage of Alzheimer`s patients who migrate to an institution. A more difficult, but perhaps more significant, statistic is the number of people migrating each year. The difficulty is that not all lost hikers are reported to law enforcement or government authorities. Often, the instructor only has to look in the yard or go down the road to find the missing hiker. Some arbitration clauses are unenforceable and, in other cases, arbitration may not be sufficient to resolve a dispute.
