Construction projects and contracts, due to their uniqueness and formalities, usually contain terms that are standard and reflect the agreed construction process in uniform standard forms. In the construction sector, there are a number of standard contracts, subcontracts, guarantees and appointment agreements published by organisations such as the Joint Contracts Tribunal (JCT), the Royal Institute of British Architects (RIBA), the Institution of Civil Engineers (ICE), etc. Such agreements may be useful, as they have a record of use between the parties and their exact meaning has been examined by case law. Specific or tailor-made contracts are often considered discouraged, as they are not duly or fair in all circumstances and are not supported by a history of jurisprudence. However, their continued use reflects the inflexible inflexibility of some parts of the industry to perceive standard contractual forms. Section 3 of the Unfair Contract Clauses Act 1977 limits the ability of the author of consumer or standard contracts to design clauses that would allow him to exclude liability in a so-called exclusion clause – the law does not in itself make ineffective provisions in other areas that appear „unfair” to the layman. If a contract is negotiated, the provisions of the law would probably not apply – the law protects from many things, but a bad open deal is not one of them. For a treaty to be treated as an accession treaty, it must be submitted on a standard form based on „Take it or leave it” and not give a party the ability to negotiate because of its unequal negotiating position. The special examination of adhesion contracts can be carried out in different ways: a standard contract (sometimes called a contract of adhesion, leonine contract, [a] the Take it-or-Leave-it or Boilerplate contract) is a contract between two parties in which the terms of the contract are set by one of the parties. and the other party has little or no ability to negotiate more favorable terms and is therefore placed in a „take it or leave it” position.

In Nigeria, common law principles and practices govern and regulate design and construction contracts. In a design or construction contract, the basics of common law agreements, parties, intentions, reflections, etc. must be gathered. Many states in Nigeria have laws that govern treaties and which laws are codified common law principles. In addition to the standard forms, construction contracts must not infringe the provisions of the relevant legislation: the Town planning and Regional Planning Act, the National Building Code 2006, the National Environmental Standards and Regulations Enforcement Agency Act 2018 (as amended), the Environmental Impact Assessment Act 1992, the Public Procurement Act 2007 and other laws regulating professionals in the construction sector such as the Builders Registrati on Act Cap B13 LFN 2004. Engineers Registration Act 2019, Quantity Surveyors Act Cap Q1 LFN 2004 and Architects Registration Act Cap A19 LFN 2004. Another factor that could mitigate the impact of competition on the content of contracts of adhesion is that, in practice, model contracts are usually drafted by lawyers responsible for constructing them in such a way as to minimize the liability of the company and not necessarily implement the decisions of managers in matters of competition. Sometimes contracts are written by an interbranch organisation and distributed to companies in this sector, which increases the homogeneity of contracts and reduces the ability of consumers to redeem themselves. Standard contracts are generally enforceable in the United States. The Uniform Commercial Code, which is applied in most U.S. states, contains specific provisions regarding standard contracts for the sale or lease of goods. In addition, model contracts are subject to special scrutiny if they are not considered to be membership contracts.
