In principle, buyer's liability principle does not ask the seller 's warranty for defect warranty. The reason is that buyers have a period to investigate the property after the sales contract (the term of investigation is referred to as due diligence (commercial property) or contingency period (residential property)) termite control company, surveyor, home Inspector and architect can investigate the property (buyer's actual expenses) sufficiently. In addition, the neutral institution investigates the survey of the owner himself / herself, the investigation of the registration relation by the system, the escrow company or the authority insurance company (title · insurance company), so if the fact is found different from the purchase and sale agreement, It is possible to cancel this sales contract without it. There is no problem even in buyer's liabilityism because a system that secures transaction safety is established.

On the other hand, from the viewpoint of consumer protection from the point of view of consumer protection, in principle, it is possible to exercise a right for one year after wounding defects as defect warranty responsibility in principle. If the seller is a real estate agent it is possible to exercise the right for two years. However, it is due to insufficient investigation institution like the United States and period as long as you can reverse it. Frequent cases occur in which a buyer becomes a trial in which the seller or the buyer is liable for the responsibility of the seller or the buyer, such as a termite problem, which was later discovered, such as the termite problem, which was insufficient in earthquake resistance, because the buyer himself did not perform precise property investigation. Although it is a consumer advantage, you should neglect neglect of property investigation and investigation of rights relationship.
