Throughout the life of an incapable adult, several events with significant legal consequences will occur. Our family and persons law lawyers<\/a> in Qu\u00e9bec City and L\u00e9vis discuss contracts signed by an incapable adult, whether or not the adult is under a protective supervision regime. For example, the contract could be a residential lease, a cellphone contract or the purchase of any kind of property.<\/p>\n\n\n\n Articles 153 and 154 of the Civil Code of Qu\u00e9bec<\/em> provide that a person who reaches full age, at 18, becomes able to fully exercise all their civil rights, and that the capacity of a person of full age can be limited only by law or by a judgment ordering the institution of a protective supervision regime. In other words, the capacity to contract<\/span> is the rule and incapacity is the exception. Moreover, for a contract to be valid, \u201c consent may be given only by a person who, at the time of manifesting such consent, either expressly or tacitly, is capable of binding himself \u201d.<\/p>\n\n\n\n An incapable adult who is not under a protective supervision regime and who wants to annul a transaction they entered into themselves will have to prove that they were incapable of consenting when the contract was made. Since the law presumes that an adult who enters into a contract has capacity, it is up to them to prove their incapacity[1]<\/a>.<\/p>\n\n\n\n If the other contracting party does not accept this incapacity, court proceedings will have to be filed to have the contract declared null. To do so, an incapable adult who relies, for example, on an illness or their mental health to show that there was no consent will have to prove, through expert evidence, that when they consented to the contract in question, they were not able to reason soundly or to understand the scope and extent of their commitment[2]<\/a>.<\/p>\n\n\n\n To succeed, an unprotected adult who wants the contract annulled will also have to prove that the contract, as concluded, causes them some prejudice; otherwise, the application will be dismissed. Of course, the adult must also be able to return the service or property they received when the contract was made. If this is impossible, the application will be dismissed on that ground.<\/p>\n\n\n\n If you are dealing with a contract you entered into at a time when you believe you were incapable of doing so, do not hesitate to contact our lawyers to have it annulled.<\/p>\n\n\n\nThe principle of legal capacity<\/strong><\/h2>\n\n\n\n
