Identify
Merryn and Helen's case relates to a simple contract which can be created verbally, in writing or by conduct of the parties. The elements of a simple contract include: Intention, Agreement (offer + acceptance), Consideration, Capacity, Genuine Consent, and Legality. The first three elements must be satisfied in all simple contracts and may create an apparent simple contract. Elements 4-6 may affect the validity of a contract.
Rules
On the first element of intention, the agreement could be regarded as one of business involving payment for a service. The law presumes that there is an intention to create legal relations in business agreements (See Edwards v Skyways). If we were to argue it is a social agreement made on a beach, the rebuttal could apply as it appears Merryn is in serious trouble and the money offered for help is quite generous.
Apply
Merryn would then appear to make a valid offer, however it is not clear that there has been a valid acceptance. An offer must be communicated to the offeree and acceptance must be made in reliance of the offer. It seems that Helen is unaware of Merryn's offer before she undertakes the task of helping her with the car before she knows there is a reward. Therefore no acceptance has been made at this stage (See R v Clarke).
Conclusion
There would also appear to be a problem with consideration. Consideration must be of a legal value and exchanged by both parties. It can be present, future but not past. It must be more than a person is already required to do by law or by contract. Since Helen tries to claim the $500 after she towed Merryn's car the consideration is past and not valid (See Roscorla v Thomas). When Helen took this action it seems to have been part of her job as a council worker and therefore the consideration is not sufficient (See Stylk v Myrick). There is no valid contract between Merryn and Helen.
