8.5.12 Exception clauses to exclude or limit the liability of a contractor are often, but not exclusive, in standard agreements. Singapore law, which refers to such clauses, is essentially based on English law. The English Unfair Contract Terms Act 1977, which invalidates either a derogation clause or restricts the effectiveness of these clauses by imposing a adequacy requirement, was reassessed in Singapore as the Unfair Contract Terms Act (Cap 396, Rev Ed 1994). The opposite is true with social agreements between friends or family, as there is a legal presumption that between social relationships, the parties do not intend to be legally bound, but if necessary, you would need a clear explanation of the intention to be legally bound. The terms of the contract should highlight the rights and obligations that each party has in relation to its previous agreement, so that the contract is considered valid. Essential terms include: the price paid for a service or service, the description of the service sold or provided, and the details of the parties to the contract. When a contract has been rewritten, Singapore does not use the Parol rule of evidence, which states that only the written contract can be used to determine the terms of the contract, either for pre-negotiations or for any other oral or written evidence. 8.8.4 First, the parties are free to enter into a contract, so that they are free to negotiate among themselves to free themselves from the obligations of that treaty. Such an agreement could, for example, have been incorporated into the original contract if the parties agree that their initial agreement may be limited by termination or after a certain period of time has expired. In addition, the contracting parties can waive the obligations of the original contract by entering into a subsequent release agreement. While each party is still subject to contractual obligations that have not yet been fulfilled, the reciprocal release of its outstanding obligations under Singapore law is generally effective, with no other formalities or consideration required.
However, if the party to whom the undertaking in question is due does not have outstanding undertakings under the original contract, the party wishing to be exempted from that obligation must pay some sort of valuable consideration in exchange for the release. Alternatively, sealed release must be executed to be effective. 8.5.3 If the parties have rescinded their agreement in writing, the question of whether a specific statement (oral or written) is part of the contract itself depends on the application of the rule of evidence.
