A more thorough explanation:

Definition: Obligationes innominati is a Latin term that refers to innominate obligations. These are obligations that do not have a specific name or classification because they are not strictly contractual, delictual, or quasi-contractual.

Examples: An example of an innominate obligation is the obligation of a trustee to a beneficiary. This obligation does not fit neatly into any of the traditional categories of obligations, but it is still legally binding. Another example could be a moral obligation to help a friend in need, which is not enforceable by law but still carries a sense of duty.

Explanation: Innominate obligations are obligations that do not fit into any of the traditional categories of obligations. They are not contractual because they do not arise from an agreement between parties. They are not delictual because they do not arise from a wrongful act. And they are not quasi-contractual because they do not arise from a situation where one party has been unjustly enriched at the expense of another. Instead, they are obligations that arise from other sources, such as moral duty or fiduciary relationships.
