Mistake and frustration

Duncan Lewis Litigation Solicitors – Mistake and frustration


Mistakes and frustration in contract law involve circumstances which make a contract unworkable.


Mistakes in the drafting of a contract can be one cause of a dispute or claim – and frustration can occur when circumstances change after the contract is signed, which make the contract unworkable or unenforceable.


A contract may become unworkable if the change in circumstances radically alters what was originally agreed or intended in the contract – for example, if changes at work alter an employee’s obligations under an employment contract.


Although neither party to a contract may be responsible for a contract becoming unworkable or incapable of being performed, it may still be possible to claim if losses are incurred as a result.


However, contract law is extremely complex and it is necessary to take legal advice as soon as possible if it becomes evident that mistakes have occurred in the drafting of a contract which have led to loss – or a contract is not workable because of a change in circumstance after the contract was signed.


Some mistakes in contracts may render the contract void – with any of the parties being able to terminate the contract.


In some cases a “common” mistake may occur – that is, a mistake which is fundamental to the agreement between the parties to the contract. In other cases, a mutual mistake might occur – where the parties have misunderstood each other’s purpose in the contract’s terms and are at cross purposes.


Unilateral mistakes may also occur in contracts – where one party has mistaken the purpose of the other party’s intentions in the contract.
