Nature of diligence required: diligence of a good father of the family unless other requirement is stipulated
Consequence: Seller will be guilty of breach if thing is lost through his fault
DELIVERY OF THE THING
Transfer ownership (tradicion)
twin obligation:
1. transfer title(ownership) SELLER must be owner of thing at the time of consummation to validly transfer title
2. delivery of the thing
Different kinds of delivery:
1. Actual
when thing sold is placed in the control & possession of the buyer
2. Constructive
DIFFERENT FORMS OF CONSTRUCTIVE DELIVERY:
1. Traditio Longa Manu
Delivery of thing by mere agreement; when SELLER points to the property without need of actually delivering
2. Traditio Brevi Manu
Before contract of sale, the would be buyer was already in possession of the would be subject matter of sale (ex: as lessee)
3. Symbolic delivery
As to movables ex: delivery of the keys to a car
4. Constitutum possessarium
at the time of perfection of contract, seller continues to hold possession merely as a holder
5. Execution:
Exception:
a. when there is stipulation to contrary, execution does not produce effect of delivery
b. when at the time of execution of instrument, subject matter was not subject to control of the seller
subject matter should be within control of seller; he should have capacity to deliver at the time of execution of public instrument when he wants to effect actual delivery
such capacity should subsist for a reasonable time after execution of instrument (reasonable time depends on circumstances of persons, places & things)
Effect when 2 requisites do not concur: no constructive delivery; no compliance on part of SELLER to deliver
Even when thing is mortgaged, seller can still deliver because naked title still belongs to him & can still do acts of ownership including conveyance
6. Negotiable documents of title & non negotiable instruments
transferee acquires title of transferor
when delivered without negotiation, it is a mere assignment
7. Intangibles/ incorporeal property
through public instrument
execution is equivalent to delivery if from the deed, contrary does not appear
