Agreement by Incompetent Parties

Agreement by Incompetent Parties: Understanding the Legal Implications

Entering into a contract or agreement involves two or more competent parties who have the legal capacity to enter the agreement. However, what happens when an incompetent party signs the document? Is the contract still binding? What are the legal implications of such an agreement?

Incompetent parties are individuals who are not legally capable of entering into a contract due to their mental incapacity, age, or lack of authority. In such cases, there are specific laws that govern the enforceability of agreements entered into by incompetent parties.

Mental Incapacity

Mental incapacity refers to a state where an individual lacks the mental capacity to understand or make rational decisions. Incompetent parties due to mental incapacity include individuals suffering from mental illnesses, dementia, or intellectual disabilities.

In cases where an individual is mentally incapable, any agreement they enter into is considered voidable. This means that the agreement is not automatically void, but the incompetent party can choose to enforce or terminate the contract at a later stage. However, if the other party was aware of the mental incapacity and took advantage of the individual, the agreement could be rendered void.


Minors, individuals under the age of 18, are legally incapable of entering into a contract except in certain circumstances. Minors are considered incompetent parties because they lack the legal capacity to enter into agreements, and any contract signed by a minor is voidable.

However, there are exceptions to this rule. For instance, minors can enter into contracts that are of benefit to them, such as employment contracts, educational contracts, and contracts for necessities like food, shelter, and clothing. Additionally, parents or guardians can enter into contracts on behalf of minors, and such agreements are considered binding.

Lack of Authority

Incompetent parties due to lack of authority include individuals who sign a contract on behalf of a company when they do not have the authority to do so. In such cases, the contract is not enforceable against the company, and the incompetent party may be held personally liable for any damages incurred.

It is essential to ensure that individuals signing contracts on behalf of a company have the legal authority to do so. This can be done by requesting proof of authorization, such as a power of attorney or an employment contract.


Agreements entered into by incompetent parties are a legal gray area, and their enforceability depends on various factors. It is crucial to consult with legal experts when dealing with contracts involving incompetent parties to ensure that the agreement is enforceable and that all legal requirements are met.
