Classification of conditions
According to Manresa, a condition is any uncertain event which wields an influence on a legal relation.[1] It is also defined by De Leon as "a future and uncertain event, upon the happening of
which, the effectivity or extinguishment of an obligation (or rights)
subject to it depends."[2] The following are the various classifications of conditions:
(1) Suspensive and resolutory;
(2) Potestative, casual and mixed;
(3) Impossible and possible;
(4) Positive and negative;
(5) Divisible and indivisible;
(6) Conjunctive and alternative; and
(7) Express and implied.
