Scope of Law on Evidence
1. Prescribes the manner of presenting evidence (Burden of Proof, rules 131-132); 2.Fixes the qualification and privilege of witnesses and the mode of examining them (Rule 132); 3.Determines among the probative matters, things which are logically and in their nature evidential, and what classes of things shall not be received. This excluding function of rules of exclusion is the chief characteristic of our law on evidence (Rules of Admissibility 128-130).
TWO PRINCIPAL PROBLEMS IN EVIDENCE: 1. How to determine which evidence is admissible; and 2. Having determined that the evidence is admissible, how to present that evidence in a manner that would make the court admit it once it is offered.

It may be ascertained in: a) pleadings submitted by the parties b) pre-trial order c) issues which are tried with the express or implied consent of the parties. (Sec. 5, Rule 10)
FACTUM PROBANS - the material evidencing the proposition. It is the fact by which the factum probandum is established.
