Perfection Stage
a. sale by owner VALID
b. sale by non-owner VALID;
because ownership is necessary only at time when transfer title to goods; at perfection stage, no obligation on part of seller to transfer ownership
law on estoppel further bolsters it: title passes by operation of law to grantee when person who is not owner of the goods sold delivers it and later on acquires title thereto
since valid, action to annul is improper; there is already a perfected contract
Consummation Stage
Contract of sale is valid because it has passed perfected stage, despite:
a. seller not being the owner
b. seller having no authority to sell
What is void is the transfer of title/ ownership did not pass
Effect: buyer acquired no better right than transferor
Legal effect: CAVEAT EMPTOR BUYER BEWARE
a. co-owner sells whole property prior to partition sale of property itself is void but valid as to his spiritual share
b. co-owner sells definite portion to partition sale is void as to other co-owner but valid as to his spiritual share if the buyer would have still bought such spiritual share had he known that the definite portion sold would not be acquired by him.
Exception to (b):
i. Subject matter is indivisible
ii. Sale of definite portion is with consent of other co-owners
iii. co-owner sells 1 of 2 commonly-owned lands & does not turn over ½ of the proceeds, other co-owner, by law & equity, has exclusive claim over remaining land.
General Rule: Sale by non-owner, buyer acquires no better title than seller had.
Exception:
a. owner by his conduct is precluded from denying sellers authority (ESTOPPEL)
b. contrary is provided for in recording laws (PD 1529)
c. sale is made under statutory power of sale or under order of a court of competent jurisdiction
d. sale is made in a merchants store in accordance with code of commerce & special laws
