Consideration & Promissory Estoppel Flashcards
Consideration
Refers to something of value that each party agrees to give or do for the other as part of a contract. It can be money, services, goods, or a promise to do (or not do) something. For a contract to be valid, there must be consideration exchanged between the parties
Rules of Consideration
- Consideration must not be in the past
- Consideration must move from the promise
- Consideration must be sufficient in the eyes of the law but need not be adequate for the promise given
- Performance of a duty imposed by law
- Performance of a contractual duty owed to a third party
- Alteration promises to pay more money
- Alteration promises to pay less money
Consideration: Practical Scenario
- I have a hamster, I will it you for 10 pounds. yes, agreed
- thank you for mowing my lawn, would you like one of my hamsters? Yes, please.
Rule #1 Consideration must not be in the past
Means that in a contract, the exchange of something valuable (consideration) cannot be based on something that has already been done. Must involve a present or future act or it is not enforceable.
Eastwood v Kenyon (1840)
Eastwood v Kenyon (1840): Eastwood was a guardian of a young heiress who borrowed 140 pounds to educate and improve her estate, she promised to repay the sum, when the money was not forthcoming Eastwood brought an action against her to enforce but the court stated it was not enforceable because the consideration was in the past.
Exception to Rule #1
- the service must have been rendered at the promisor’s request
- The parties must have understood that the act would be paid for, or that the other party would derive some benefit
- payment would be legally enforceable had the promise been made
Lampleigh v Braithwaite (1615)
Braithwaite was found guilty of murder and was in prison. The defendant approached the plaintiff and said to go to the king and ask for a pardon on his behalf, he did and went to the plaintiff several times and asked for the pardon and he in fact is granted the pardon, Braithwate says to the plaintiff when he comes out of prison he will pay him 100 pounds. The exchange already happened in the past - he was asked to complete the act by the defendant, and the court said a voluntary act done before the promise is made would not constitute good consideration. He did not act voluntarily and was asked to go to the king and ask for pardon. Exception: past consideration can be valid it it was performed at the request of the promisor.
Re Casey’s Patent (1892)
Normally, if you do something for someone and they later promise to pay you, that promise isn’t enforceable because the act was already done without any prior agreement.
In Re Casey’s Patents, Casey helped manage patents, and afterward, he was promised a share in them as a reward. The court held that this was enforceable because:
The work was done at the request of the other party (not just volunteered).
There was an implied promise that Casey would be paid in some way for his work, even if the exact terms were decided later.
So, if the service is done with an expectation of payment and later a promise is made, it can still count as valid consideration.
Pau On v Lau Yin Long (1979)
In this case, Pao On agreed to delay selling shares to protect the company’s value, and Lau Yiu Long later promised to compensate him. The court said the promise was enforceable because:
The act (delaying the sale) was done at the promisor’s request.
There was an understanding that the act would be compensated later.
The promise would have been enforceable if it had been made in advance.
So, past consideration is valid if the act was done at someone’s request, with an expectation of payment, and later formalized.
Rule #2: Consideration must move from the promisee
the person who is receiving the promise (the promises) must give something of value in return for the promise. this means that only the person who provides consideration (something of value: i.e. money or services) can enforce the promise made in the contract. If the promise doesn’t provide anything of value, they can’t hold the other party to their promise.
the consideration does not need to move directly to the promisor (the person making the promise). It can move to a third party instead. the only thing that matters is that the promise gives something of value as part of the agreement, whether it benefits the promisor or someone else. the thing that you give in exchange for the promise has to come from you the promisor, it cannot come from someone outside the agreement.
Tweedle v Atkinson (1861)
Two fathers agreed to give an allowance to their children, who had just married. The bride’s father died before paying any money. Tweedle was intended to be the beneficiary of the agreement, but he did not provide any consideration (he didn’t give anything of value in return for the promises made by the fathers) Tweedle Junior brought an action against the estate to enforce the promise. the court ruled that Tweedle could not enforce the contract because he had provided no consideration. although the agreement was made for his benefit, he wasn’t part of the value exchange between the two fathers. the court emphasized that a person who is not part of the consideration cannot enforce a contract, even if it was made for their benefit. It shows that while the benefit of the contract could go to a third party (tweedle), the third party still cannot enforce the contract unless they have themselves provided consideration.
Rule #3: Consideration must be sufficient in the eyes of the law but need not be adequate for the promise given
In a legal context, sufficiency means consideration (the thing of value being exchanged) has to have some value in the eyes of the law. It doesn’t have to be money - it could be a service, a promise, or an object - but it must be something the law considers valid.
Adequacy means the law doesn’t care if the consideration is a fair or equal exchange. For example, if someone agrees to sell their car for $1, as long as both parties agree to the terms, the law will still recognize the contract, even though $1 is not an “adequate” price for a car. the value exchanged doesn’t have to match in terms of worth - it just has to exist.
As long as something of legal value is given, the courts will uphold the contract, even if one party gets a much better deal than the other.
Example: If I promise to sell you my car that is worth $30,000 for $1 would be sufficient. It doesn’t need to be equivalent in value.
Giving up something you had no right to do in the first place is not good consideration.
Exception: BUT if you exceed a legally imposed duty that can amount to good consideration.
Thomas v Thomas (1842) (Adequacy)
Before Mr. Thomas died he stated he wants his wife Mrs. Thomas, to be allowed to live in one of his houses. After his death, his executors agreed to let her stay in the house for a rent of 1 pound per year and required her to keep the house in good repair. Later, the executors tried to remove her from the house, and she took them to court. the court held that the 1 pound per year and her agreement to maintaim the house were valid consideration, even though the rent was far below what the property was worth. The court didn’t care that the rent was not “adequate” or a fair price for living in the house. what mattered was that there was “sufficient” consideration: Mrs. Thomas agreed to pay something of value (the 1 pound and the promise to maintin the house), which made the agreement legally binding.
Chappell & Co Ltd v Nestle (1960) Sufficiency
The case demonstrates the principle that consideration must be suffificent but need not be adequate in the eyes of the law. Nestle ran a promotion where customers could get a music record (a copyright song owned by Chappell & Co) by sending in three chocolate bar wrappers along with a small payment. Chappell & Co argued that the chocolate wrappers had no real value and shouldn’t count as part of the consideration. They claimed the promotion infringed on their copyright, as it allowed people to get the records too cheaply. The court had to decide whether the chocolate wrappers could be considerded valid consideration. The House of Lords ruled that the wrappers were sufficient consideration, even though they were essentially worthless once used. The wrappers were seen as part of the deal because customers had to go out and by the chocolate bars in order to participate in the promotion. The case settles the sufficiency aspect by affirming that consideration doesn’t need to have a high or marketable value (it doesn’t need to be “adequate”), but it must be something of legal value - in this case, buying the chocolate and sending in the wrappers fulfilled this requirement. The key is that the consideration was something Nestle asked for in exchange for the record, so it was sufficient for the contract, even if it was trival in value.
Ward v Byham (1956) Sufficiency
A mother (Ms. Ward) was promised by the father of their child that he would pay her 1 pound per week if she ensured that their child was “well looked after and happy.” At the time, the mother alreadt had a legal duty to care for the child, so the father argued that her promise to look after the child wasn’t valid consideration since she was already required by law to do so. However, the court held that the mother’s promise to kepp the child happy and well looked after was sufficient consideration. Even though she had a legal duty to care dor the child, going beyond that duty (ensuring the child was happy, which wasn’t a strict legal requirement) was something extra she promised to do. The court ruled that this went beyond her existing obligations, and therefore, it was sufficient consideration ti make the father’s promise of payement enforceable. This case demonstrates the sufficiency doesn’t mean the consideration has to be entirely new or extraordinary; it simply has to be something that the law recognizes as having some value, even if it is related to an existing obligation. In this case, ensuring the child was happy was considered sufficient consideration, making the father’s promise enforceable.
Rule #4: Performance of a duty imposed by law
Performance of a legal obligation (something the law tells you to do) is not a consideration for a promise. BUT if you exceed a duty imposed by law it will amount to good consideration. For example: this could be an obligation like following traffic laws, paying taxes, or, as in the example of parenting, providing basic care for your child. If you promise to do something that you are already legally required to do (your legal duty), this does not count as valid consideration for a new contract. you can’t use an existing legal obligagtion as the “something of value” to enforce a promise from someone else. For example, a police officer can’t ask for extra payement their regular duties, like investigating a crime, because that’s something they already required to do by law.
Collins v Godfrey (1813)
Collins was subpoenaed (legally required) to appear as a witness in a court case. Godfrey promised to pay him for his time if he testified. However, Collins was laready obligated by law to attent court because of the subpoena. When Godfrey refused to pay, Collins tried to enforce the promise. The court ruled that Collins could not enforce the promise becuase he was already legally required to attent court as a witness under the subpoena. since Collins was performing a duty that the law imposed on him, his act of attending court could not could not count as valid consideration. In other words, you can’t enforce a contract if the only thing you are offering in return is something you’re already legally bound to do. Doing something you’re already required to do by law - like testifying in ocurt - doesn’t provide sufficient consideration to create a new contract.
Glasbrook Bros v Glamorgan County Council (1925)
Minors strike, the owners of a mine whose workers were on strike sought the assistance of the police to get the men who weren’t stiking across to their jobs and wanted the police to come and maintain order, the police came and inspected the situation saying that a mobile police escort would be sufficient. The mine owners wanted on the spot coverage and would pay them for doing so. The owners of the mine refused to pay and said it is their legal obligation to make sure something is maintained. The House of Lords sided with the police and that mobile coverage should be compensated because providing this act was going beyong their legal obligation.
