How long is the advance notice registration valid?

Legal analysis: According to the provisions of China's Civil Code, the validity period of advance notice registration is generally 90 days. If it is not registered for more than 90 days, the advance notice registration is invalid.

Legal basis: Article 221 of the Civil Law of People's Republic of China (PRC) stipulates that if a party signs a house purchase and sale agreement or other agreement on real property rights, it may apply to the registration authority for advance notice registration in order to ensure the realization of future real property rights. After the advance notice registration, if the obligee without advance notice registration agrees to dispose of the real estate, the real right effect will not occur. After the advance notice registration, the creditor's rights are extinguished or the application for registration is not made within 90 days from the date when the real estate registration can be carried out, and the advance notice registration is invalid.
