Disclaimers in contracts are generally included when one party wants to sell a product or service without any guarantee of its quality (merchantability) or suitability for the buyer’s intended use. Guarantees of a product’s quality or suitability are also known as warranties, and may be implied in the parties’ agreement without being written or spoken—usually by virtue of a state’s statutes adopting the Uniform Commercial Code’s provisions governing the sale of goods (Article 2)—or by court opinions (also known as common law or case law). Some states have laws (statutes) that prohibit the disclaimer of warranties; make disclaimers ineffective; and penalize parties who attempt to disclaim such warranties. Disclaimers in contracts also serve as an explicit warning to the parties of the risks in a sale or transaction and help avoid a subsequent claim that a party was unaware of such risks or was deceived regarding the presence of such risks.

In Maine, disclaimers in contracts are subject to both the Uniform Commercial Code (UCC) as adopted by the state and the Maine Revised Statutes. Under the UCC, which Maine has adopted, sellers can disclaim implied warranties of merchantability and fitness for a particular purpose, but such disclaimers must be conspicuous and specifically worded to be effective. For example, to disclaim the implied warranty of merchantability, the language must mention 'merchantability' and in case of a written disclaimer, it must be conspicuous. To disclaim the implied warranty of fitness, the disclaimer must be in writing and conspicuous. Maine law also requires that any exclusion or modification of warranties be in language that is clear and understandable. If a disclaimer does not comply with these requirements, it may be deemed ineffective. Additionally, Maine's consumer protection laws may impact the enforceability of disclaimers and warranties, particularly in consumer transactions, to prevent deceptive practices. It is important for parties in Maine to carefully draft disclaimers to ensure they comply with applicable laws and fully inform the parties of the risks involved in the transaction.
