Law on Contracts

Article 1156 to 1430 of the New Civil Code – law of obligations and contracts

Obligation – Latin word “obligare” meaning to bind.
- a juridical necessity to give, to do or not to do.

Obligation to give:
“A” entered into contract with “B” whereby the former bound himself to
deliver to “B” a specific car on June 5, 2005.

Obligation to do:
“A” and “B” entered into an agreement whereby the former obliged
himself to fix the car of “B”.

Obligation not to do:
“A” and “B” signed a contract whereby the former bound himself with
“B” not to construct a fence on a land belonging to the latter for the
period of (5) years.

4 (four) Essential Requisites of Obligation:
1. A passive subject –the person who is bound or has the duty to fulfill the obligation,
called the debtor or obligor.

2. An active subject – the person who can demand the fulfillment of the object or
presentation, called the creditor or obligee.

3. An object or presentation – this is the subject matter of the obligation. It is either the
giving of a thing, or the doing, or not the doing of something.

4. A juridical tie, legal tie or the vinculum – it is that which binds the parties to the
obligation. It is otherwise known as the efficient cause.

Example:
“X” promised to design and create a computerized appliance
controller system for “Y” for one million pesos by virtue of
contract signed by them.

Passive subject : “X”
Active subject : “Y”
Object or presentation : Creation of Computerized appliance controller system
Juridical or legal tie : Contract

If it was agreed that after the creation:
Passive subject : “Y”
Active subject : “X”

Sources of Obligations:
a. Derived from Law – determined in the Civil Code or in special laws are demandable and
shall be regulated by the precepts of the law.
Example:
Obligation of the spouses to mutually support each other
Obligation to pay taxes pursuant to the National Internal Revenue Code

b. Derived from Contracts – the force of law between the contracting parties and should be
complied with in good faith. The contract must be valid and enforceable and must not be
contrary to law, morals, good customs, public order or public policy.
Example:
1. “X” agrees to sell his car to “Y” and the latter agrees to buy the
car of “X” voluntarily.
- The agreement has the force of law. Thus, neither may not violate the
terms and conditions of the contract for it is required by the law that the
same must be complied with in good faith.

2. “A” agrees with “B” to steal the car of “C” for in consideration of
P2,000.00.

- This contract is “void ab initio” for it is contrary to law.

c. Derived from quasi-contracts – lacks the element of consent, and no formal contract
between the parties. However, the law considers them to have entered into an
agreement purposely to prevent injustice.

2 (two) kinds of quasi-contracts
(a) negotiorum gestio – it is the voluntary management of the property or
affairs of another without the knowledge or consent of the latter.
Example:
“A” went abroad with his family without leaving
anybody to look after his house. While abroad, a strong
earthquake occurred resulting in the destruction of “A’s”
house. Because of the magnanimity of “B”, “A’s” neighbor,
the house was repaired with some expenses. In this case,
“A” is obliged to reimburse the expenses of “B”.

(b) solution indebiti - it is a juridical relation which takes place when
something is received when there is no right to demand it, and it was
unduly delivered through mistake, giving rise to the obligation to
return it.
Example:
“A” owes “B” the sum of P2,000.00. “A” paid “B” the
sum of P3,000.00 not knowing that the former incurred only
a debt amounting to P2,000.00. In this example, “B” is
duty-bound to return the excess of P1,000.00.



d. Derived from delicts or crimes – person committing a criminal offense is obliged to pay
for the injury thus inflicted.
Crimes or delicts – acts or omissions punished by law (felony).

Example:
“A” boloed “B” resulting in the latter’s death. If “A’ is found
guilty thereof, he is liable to indemnify the heirs of the
deceased.

e. Derived from Quasi-delicts – an act or omission by one person which causes damage to
another giving rise to the obligation to pay for the damage done, there being fault or
negligence, and there is no pre-existing contractual relation between the parties.
Example:
In a pedestrian, one who was hit by a speeding jeepney due to
negligence

Persons liable for damages arising from quasi-delicts:
a. Father or mother
b. Guardians
c. Owners and managers of an establishment or enterprise
d. Employers
e. The state
f. Teachers or heads of establishments of arts and trades

Nature and Effect of Obligation:

• Obligation to be diligent – “Every person obliged to give something is also obliged to
take care of it with the proper diligence of a good father of the family, unless the law
or the stipulation of the parties requires another standard of care.”
Example:
“A” binds himself to deliver to “B” a specific race horse on
certain day. Before the arrival of the agreed upon, “A” has the
accessory obligation to take care of the horse such as feeding it
regularly until he actually delivers the horse on the specified
date. If the horse dies as a result of “A’s” failure to exercise
proper diligence he shall be liable for damages.

• Obligation to give a determinate thing – delivering all its accessions ad accessories
even though they may not have been mentioned.
Accession – pertains to the fruits of a thing or additions to or improvements
upon a thing such as trees planted on a land, and rents on buildings.
Accessories – pertains to things joined to or included with the principal thing
for the latter’s embellishment such as frame of the picture, keys of the
car, etc.

• Obligation to do – if a person obliged to do something fails to do it, the same shall be
executed at his cost.
Example:



“A” binds himself to construct a building for “B”. However, it
was constructed in accordance with the agreed plans an
specification. In this case, it may be ordered undone.
• Obligation not to do – when the obligation consists in not doing, and the obligor does
what has been forbidden him, it shall be undone at his expense.
Example:
“A” and “B” agreed that the latter will not construct an
adjoining fence between their lands for a certain period. IF “B”
violates the agreement, the same shall be demolished at his
expense.

• Obligation to deliver – the obligor may bind himself to deliver either a specific
(determinate) or generic (indeterminate) thing.

Rights to the fruits:
• Natural fruits
• Industrial fruits
• Civil Fruits
Example:

“A” binds himself to deliver the land to “B” on February 5,
2006”. Before this date, “B” has no rights over the fruits of the
land. After Feb. 5, 2006 he has perfect rights over the same.
However, if “A” actually delivered the land on Feb 25, 2006, “B”
could only acquire real right (ownership) over the land on such
date.

Primary classifications of Obligations:
a. Pure and conditional obligations
Pure obligation – an obligation which is not subject to any condition or burden.
Example:
“A” promised to give “B” the sum of P1,000.00
Meaning:
The obligation to pay is demandable at once because there is no
specific date mentioned for its performance. Neither is it subject to any
condition imposed for its fulfillment.

Conditional obligation – an obligation whose performance is subject to any condition.
Example #1:
“A” binds himself to give “B” a car as soon as “A’s” mother
arrives from Canada.
Meaning:
The obligation is demandable only upon the fulfillment of the
conditions the arrival of the mother.
Example #2:
I will allow you to use my car until you pass the Bar
Examinations.
Meaning:
The obligation is immediately demandable but it will be extinguished
upon the happening of the condition, that is, the passing of the Bar
examinations.


b. Obligations with a period – an obligation whose performance is subject to the expiration
of said period or term.
Example:
1. I will give you a gift on your birthday.
2. I will give you a 200 peso allowance until you finish your course.
3. Payment of taxes.

c. Alternative and facultative obligations
Alternative obligation – various presentations are due, but the performance of one of
them is sufficient determined by the choice which rightfully belongs to the
debtor (obligor) unless it has been granted expressly to the creditor (oblige)

Example:
“A” binds himself to deliver to “B” either a gold ring or a gold
watch.
Meaning:
“A” should deliver one of them and it is required that the performance must
be complete, that is, he cannot deliver the stone of the ring or bracelet of the
watch.

Facultative obligation – an obligation where one presentation is due but the obligor
(debtor) may substitute another.

d. Joint and solidary obligations
e. Divisible and indivisible obligations
f. Obligations with a penal clause

Secondary classification of obligations:
a. Unilateral and bilateral obligations
b. Real and personal obligations
c. Determinate and generic obligations
d. Civil and natural obligations
e. Legal, conventional and penal obligations

MEANING OF CONTRACT:
Contract – is a meeting of minds between two persons whereby one binds himself, with
respect to the other, to give something or to render some service.

- it is a juridical convention manifested in legal form, by virtue of which one or
more persons bind themselves in favor of another or others, or reciprocally, to
the fulfillment of a presentation to give, to do or not to do.

Difference between contract and obligation:
- Contract is one of the sources of obligation, while the latter is the legal relation itself.
- Contract is the very agreement of the parties; while the obligation is the remedy which the
law affords for its enforcement.

Example of Contract to give something:
“A” offers to sell to “B” his 1995 Toyota Corolla car for P50,000.00.
“B” accepts the offer for such amount.


Since there is a contract, “A” must deliver the car to “B”, but the latter is obliged to
pay the amount agreed upon”.

Example of Contract to render some service:
“A” binds himself to construct the house of “B” for P100,000.00.
