NEGOTIORUM GESTIO
Article 2144. Whoever voluntarily takes charge
of the agency or management of the business
or property of another, without any power from
the latter, is obliged to continue the same until
the termination of the affair and its incidents, or
to require the person concerned to substitute
him, if the owner is in a position to do so. This
juridical relation does not arise in either of these
instances:
(1) When the property or business is not
neglected or abandoned;
(2) If in fact the manager has been tacitly
authorized by the owner.
