Yes, in the UK, there is a legal obligation to disclose the presence of asbestos when selling a house. Sellers are required to provide information about any known asbestos-containing materials (ACMs) in the property. This disclosure is typically included in the Property Information Form (TA6) as part of the conveyancing process. It is crucial for sellers to be transparent about the presence of asbestos to ensure that buyers are informed about potential risks and can make well-informed decisions. Failing to disclose asbestos may lead to legal issues and financial consequences. Therefore, it is advisable for sellers to conduct an asbestos survey and share the findings with potential buyers during the property transaction.
