Introduction "Introduction to business law in Singapore" was sold by Alan to three different people, namelyBernard, Charleen and Damien. Later, Bernard and Damien realized that the book had been releasedfree of charge by Kaplan. Legal issues involve whether a contract is formed between the partiesinvolved and the role of the individual in the case. At the same time, possible alternatives to handlingthe problem, other than compensation, should also be proposed.1.Contract formation IssueBernard, Charleen and Damien conducted different transactions with Alan for the same book thatwas released free of charge by Kaplan. This dispute will need to prove whether there are any legallybinding contracts between the parties that have been established.RuleBased on the Australian Contract Law, a property purchase agreement is only valid when parties are21 years of age or older. This contract is only valid if the parties agree to accept the offer. In general,there are four basic principles for creating a contract: the legal capacity of the parties, theagreement, the consideration and an intention to create legal relations.A contract is valid when it is an agreement, including "offer" and "acceptance". It means there isconsensus among the parties. These agreements are only considered effective when the aspects areclear. Therefore, a "vague" agreement, incomplete or constitutes a contract and will not be enforced.A consideration is mandatory by the Australian Government to ensure the benefits of parties, whichstipulates that gratuitous promises will not be made. However, according to the doctrine ofpromissory estoppel the execution of the agreement even lacks the existence of a valid review. This ismeant to protect the promisee in case the promisor denied the responsibility of the view and allegesthat the promise was not enforced lawfully.A contract is legal when the parties intend to create a legal relationship. Mostly, when aconsideration of the parties is conducted will be evidence to prove intention, but not always. Inspecific cases, the court will require proof of onus to conduct the investigation. Often, commercialtransactions will be considered legal consequences while social commitments are not.In the case there is a social and domestic relationship, which meaning the relationship betweenfriend or family, it will be considered as no intention of binding a legal contract. ApplicationBased on below points, there is no legal contract between Alan and any other parties. However, Alandid not provide exactly goods as he offered to Bernard and Damien. Besides, due to the fact that thematerial was issued free of charge by Kaplan, it is considered as Alan had a misrepresentation tomake Bernard and Damien to buy the book. This fact allow Bernard and Damien had a legal rightrevoke the contract and ask for a refund from Alan.
