In addition to these classic contracts, new special contract types are constantly being found in general contract law in legal practice that are not explicitly regulated by law, such as leasing contracts and franchise contracts. These are often hybrids of the classic contract types, so they usually contain elements of different “classic” contract types and combine them.
General contract law is understood to be the entirety of legal provisions that deal with private law contracts and contract types of all kinds and the legal relationships between the contracting parties.
