Restrictive alliances were once used for racial discrimination, which in particular prohibits the sale of real estate to certain minorities. This practice is no longer legal. The most common restrictive agreements are found in employment contracts. These agreements generally prohibit workers from taking certain measures either during the term of employment or for a period after the end of employment. The scope of the clauses must therefore be related to the position of the worker within the company. As more older workers will come into contact with more sensitive information, the restrictions imposed on them may be more painfully justified. Overall, a uniform policy on restrictive contractual clauses may prevent the clause from being applied. There are restrictive agreements in real estate to prohibit, in some way, the use of real estate by tenants, landlords or other residents. Such restrictions often exist in closed communities and condominiums. Many of these restrictions often focus on maintaining a style, appearance or functionality of the community. Confidentiality agreements are often used when a company excludes the service contracts of a freelancer or other independent contractor. Freelancers do not have the inherent loyalty of the company, but they can acquire valuable information about it in collaboration with employees. Whether restrictive alliances are applicable or not and to what extent is largely dependent on state laws (and can therefore vary considerably from state to state).

Most states set different rules on the types of clauses that are allowed in restrictive contractual agreements. A new owner may want the former owner/seller to sign a non-compete agreement that prevents him from competing in the sale of a business. The new owner could also restrict the former owner`s ability to recruit staff or recruit existing clients or limit disclosure. The Confederation will generally be written in fact, and must be written under the statutes of fraud. Although scientists have argued that some of the following should be significantly reduced, the burden on the country must be as follows:[12] In general, the more negative alliances in a bond issue, the lower the interest rate on the debt, as restrictive alliances will make bonds safer for investors. If restrictive real estate alliances are passed from one landowner to another, the restrictions must „run with the land.“ If a person violates one or more of the covenants or attempts to violate them, a person who benefits from the covenants, usually a neighbouring owner, can take legal action to enforce the restrictions.
