The outdated PRC Security Law (1995) had allowed the relevant parties to agree to having a security agreement to remain valid, even if the underlying agreement is found to be invalid. The introduction of the PRC Property Law in 2007 substantially changed this general rule and provided that a security over personal property, real estate, or other property such as shares cannot remain valid if the underlying agreement is found to be invalid. The two laws were repealed by the PRC Civil Code now.
