Meeting of minds between two persons whereby one binds himself, with respect to the other, to give something or to render some service.
Contracts
Is the legal tie or relation itself that exists after a contract has been entered into.
Obligation
Agreements which cannot be enforced by action in the courts of justice (like an agreement to go to a dance party) are not contracts but merely moral obligations.
Moral or Social Agreement
Deal with norms of good and right conduct evolved in a community. These norms may differ at different times and places and with each group of people.
Morals
Refers principally to public safety although it has been considered to mean also the public weal.
Public Order
Is broader than public order, as the former may refer not only to public safety but also to considerations which are moved by the common good.
Public Policy
Is an agreement which gives rise to obligations. It must bind both parties in order that it can be enforced against either. Without this equality between the parties, it cannot be said that the contract has the force of law between them.
Contract
That which requires compliance with certain formalities prescribed by law (e.g. donation of real property which must be in a public instrument).
Solemn Contract
that which is perfected by mere consent. (e.g. sale, lease, agency)
Consensual contract
This includes all the steps taken by the parties leading to the perfection of the contract. At this stage, the parties have not yet arrived at any definite agreement.
Preparation or negotiation
that which is perfected by the delivery of the thing subject matter of the contract. (e.g. pledge)
Real contract
This is when the parties have come to a definite agreement or meeting of the minds regarding the subject matter and cause of the contract.
Perfection or birth
This is when the parties have performed their respective obligations and the contract may be said to have been fully accomplished or executed, resulting in the extinguishment or termination thereof.
Consummation or termination
Essential Requisites of Contracts
a. Consent of the contracting parties
b. Object certain which is the subject matter of the contract
c. Cause of the obligation which is established
Those present in all contracts, namely, consent, object, and cause.
Common
Those without which no contract can validly exist. They are also known as requisites of a contract.
Essential elements
Those not common to all contracts or those which must be present only in, or peculiar to, certain specified contracts.
Special
Those that are presumed to exist in certain contracts unless the contrary is expressly stipulated by the parties, like warranty against eviction or warranty against hidden defects in sale.
Natural elements
Or the particular stipulations, clauses, terms, or conditions established by the parties in their contract like conditions, period, interest, penalty, etc. And, therefore, they exist only when they are expressly provided by the parties.
Accidental errors
The meeting of minds between the parties on the subject matter and the cause which are to constitute the contract.
Consent
A proposal made by one party to another to enter into a contract. It is more than an expression of desire or hope. It is really a promise to act or to refrain from acting on condition that the terms thereof are accepted by the person (offeree) to whom it is made.
Offer
The manifestation by the offeree of his assent to the terms of the offer. Without acceptance, there can be no meeting of the minds between two parties. The acceptance of an offer must be absolute or unqualified. It must be identical in all respects with that of the offer so as to produce consent or meeting of the minds.
Acceptance
A temporary period of sanity. A contract entered into by an insane or demented person during a lucid interval is valid. It must be shown, however, that there is a full return of the mind to sanity as to enable him to understand the contract he is entering into.
Lucid interval
the false notion of a thing or a fact material to the contract.
