Cannot be the object of a contract; cannot be sold as it will belong to you anyway when the person dies
Impossible things
Cannot be the object of contracts, e.g. selling a ghost, building a building in 1 day
The fact that the quantity is not determinate shall not be an obstacle to the existence of the contract, provided it is possible to determine the same, without the need of a new contract between the parties
Requisites for the object of a contract
The thing or service must be within the commerce of man
Must be transmissible
Must not be contrary to law, morals, good customs, public order, or public policy
Must not be impossible
Must be determinate as to its kind or determinable without the need of a new contract or agreement
Things considered outside the commerce of men
Personal rights, the status and capacity of persons, honorary titles and distinctions
Public offices
Political rights of an individual or right of suffrage
Property pertaining to public dominion, such as roads, plazas, and rivers
Sacred or common things like the air and sea, as long as they have not been appropriated
Before a land can be appropriated, there must be a declaration from the government of private ownership, except for ancestral lands
CO2 is considered a common thing, but the chemicals in a hospital are not common as they have been appropriated
When paying for air to inflate a tire, you are paying for the service, not the air itself
Sale of future things (emptio rei speratae)
Things having potential existence may be the object of a contract of sale, subject to the condition that it will come into existence. If the thing will not materialize, the sale is not effective.
Sale of hope (emptio spei)
The hope or expectancy already exists, but sale of vain hope or expectancy is void.
Future inheritance cannot be the object of a contract, except under certain provisions in the Family Code and Civil Code
Cause/Consideration
The essential and impelling reason why a party assumes an obligation
Cause
The "why of the contract", the essential reason which impels the contracting parties to enter into the contract
Requisites of Cause
It must exist
It must be real, that is, true
It must be lawful
Kinds of contracts according to cause
Onerous - cause is the prestation or promise of a thing or service by the other or the promise that the parties are reciprocally obligated to each other
Remuneratory - cause is the service or benefit which is remunerated
Gratuitous - cause is the mere liberality of the benefactor or giver
Motive
The psychological, individual and personal reason which induces a party to enter into a contract
If the consideration is legal but the motive is illegal, the contract may still be valid
Cause vs Motive
Cause is the immediate, direct and most proximate reason; motive is the indirect and remote reason
Cause is the objective, intrinsic reason of the contract; motive is the individual and purely personal reason
The motive may be unknown to the other, the cause is always known
The motive may be lawful or unlawful, the cause must always be lawful
If the cause of the contracting parties is unlawful, the contract is void. If only the motive is unlawful, the contract may still be valid if the cause is lawful.
Example of valid contract with unlawful motive
K wanted to kill D and hired H to do it. K sold his land to B for P50k to fund the planned execution. The contract between K and B is valid because the object is the land, the cause is P50k, and the motive to kill D is unlawful but the cause is lawful.
Cause distinguished from object and motive
Cause is the essential reason, object is the thing/service, motive is the personal reason
Falsity of cause
The cause is false if it is fictitious or simulated. If the cause is false, the contract is considered voidable, not void, if there is another true and lawful cause.
Example of false cause
Contract stated S delivered land to B and B paid P10k, but no payment was made. However, the contract may be valid if it can be proven the true cause was a donation.
Want of cause, illegal cause, false cause
Want of cause - total lack of consideration (void)
Illegal cause - contrary to law, morals, etc. (void)
False cause - stated cause is not true (voidable)
The cause of a contract need not be stated as it is presumed to exist and be lawful
Lesion
The insufficiency or inadequacy of the cause of a contract
Lesion or inadequacy of cause does not invalidate a contract unless there is fraud, mistake or undue influence
Gross inadequacy of price does not affect the validity of a contract of sale, unless it indicates a defect in the consent of the parties
As a rule, a contract is valid and enforceable even if entered into orally, as long as the 3 essential elements are present
Undue Influence
Effect if the cause is inadequate: the contract remains valid, because lesion or inadequacy of cause shall not invalidate a contract unless there has been fraud, mistake or undue influence
Undue Influence
S sold to B a specific parcel of land valued at P1M for P100K only. The contract of sale remains to be valid.
Gross insufficiency does not mean the contract is invalid
Gross insufficiency will not invalidate the contract, unless there is either fraud, mistake or undue influence
Contract
Perfected by mere consent, once agreed the contract is valid either written or not
Classifications of contracts
Valid
Void
Voidable
Unenforceable
Voidable contract
Valid until annulled, e.g. due to problem with consent like minority
Unenforceable contract
Not enforceable but still valid
Unenforceable contract
S sold to B a specific parcel of land orally for P10K. The sale is valid but unenforceable because the law requires sale of immovable property to be in writing.
Oral contract for sale of land is valid but unenforceable
