30 Security a core aim and value in the law on non-contractual obligations

The protection and promotion of security is a core aim and value in the law on non-contractual obligations. These branches of the law can be regarded as supplementing contract law. Under contract law parties typically acquire assets. The protection of assets once acquired and the protection from infringement of innate rights of personality is not something which contract law is able to provide. That is the task of the law on non-contractual liability for damage (Book VI). A person who has parted with something without a legal basis, e. g. because the contract which prompted the performance is void, must be able to recover it. That is provided for in the law on unjustified enrichment (Book VII). In cases in which one party would have wanted action to be taken, in particular where help is rendered, but due to the pressure of circumstances or in a case of emergency it is not possible to obtain that party's consent, the situation has a resemblance to contract. But the security which would normally be provided for both parties by the conclusion of a contract for necessary services has to be provided by the rules on benevolent intervention in another's affairs (Book V).
