Obligations for whose fulfillment a day certain has been fixed, shall be demandable only when that day comes.
Obligations with a resolutory period take effect at once, but terminate upon arrival of the day certain.
A day certain is understood to be that which must necessarily come, although it may not be known when.
If the uncertainty consists in whether the day will come or not, the obligation is conditional, and it shall be regulated by the rules of the preceding Section. (1125a)
Ang mga obligasyon na kung saan ang katuparan ay naitakda na sa tiyak na araw ay mahihingi lamang sa pagdating ng araw na naitakda.
Ang mga obligasyon na may resolutory period ay magkakabisa agad, ngunit ito ay matatapos sa pagdating ng tiyak na araw.
Ang tiyak na araw ay malinaw na kailangang dumating, bagaman maaaring hindi alam kung kailan.
Kung may pag-aalinlangan sa pagdating ng araw na ito o hindi, ang obligasyon ay kondisyonal, at ito ay pinapatakbo ng patakaran ng susunod na seksyon.
Discussion:
Period and term have the same meaning and are used interchangeably. It consists in a space or length of time upon the arrival of which, the demandability or extinguishment of an obligation is determined.
General classification of terms or period in Roman Law
1. Ex Die – a term or period with a suspensive effect, which means the obligation becomes effective only from the arrival of a certain day.
Illustration: Joey promises to support Rachel from the death of Rachel’s father, which means the obligation only begins from the death of Rachel’s father.
2. In Diem – a term or period with a resolutory effect, which means the obligation will subsist up to a certain day and it terminates upon the arrival of that day.
Illustration: Joey promises to support Rachel until Rachel reaches her majority age, which means the obligation is already effective but will terminate once Rachel turns 18.
Other classifications:
1. Legal – when period is fixed by law;
2. Voluntary – when the period is agreed upon by the parties;
3. Judicial – when the period is fixed by the court for the performance of the obligation or for its extinguishment
