Admissibility Of Evidence In Nigerian Law
The law governing the admissibility of evidence is found in the Nigerian law of Evidence. Issues relating to competence and compellability of child evidence have been accorded much attention by the judiciary in making sure that children in given evidence in court are not misled. The idea of competency and compellability as it relates to the evidence of children allows the court to ensure that a child gives rational answers to questions put to him.
At common law, it is not all evidence given in court that may be held admissible. For instance, before a child can give evidence which will be admitted, such child must be a compellable witness. Therefore, a proper attention will be given to the definition of competence and compellability, its nature and principles and the position it occupies in the law of evidence.
It is also pertinent to addressing who a child is in law; the conditions which such child must satisfy before he becomes a competent and compellable witness. Importantly to note is the fact that given of evidence by a child may have some negative effect, and it has been advocated that there should be a systematic way of receiving a child’s evidence with proper consideration of the situation of the child and determination of whether the child is induced by a third party
Also, attention will be paid to the effect of giving evidence in court and why most children may feel reluctant to give evidence in court as well as the issues of risk of hysterical intention, childish imagination and collisions which may be inherent in the evidence of a child in Nigerian courts.

1.6 LITERATURE REVIEW
The fact that this area of law is not novel cannot be denied as there are sufficiently available texts, journals and learned articles in which opinions have been expressed on almost every aspect of the law in this area in Nigeria. It is not however being suggested that this long essay would be copying the works of others in to this essay, but to find a strong foundation for the present presentations and to examine earlier options. After all, precedents thrive well in law. As a result of this, the Evidence Act, the Criminal Procedure Act, the Children and Young Persons Act whose provisions will be useful in defining who a child is, is worthy of reference. Other materials to be appraised include the works on law of Evidence of learned authors like Aguda on Law and Practice relating to Evidence in Nigeria, Nwadialo Fedelis on Modern Nigerian Law of Evidence, Afe Babalola on Law and practice of Evidence in Nigeria, Christopher Allens on Practical Guide to Evidence, Oji’s Competence of Children as witnesses would be a matter of close scrutiny. It is important to add that because of constraint of time and space, not all the various materials source employed in this work are fully reviewed except those that are of direct importance to the subject matter of this work.
1.7 DEFINITION OF TERMS
The following are the terms that will be used in this research work:
Competence- The ability to do something well 
Compellability:- The ability to use coercion on an individual to do that which he ought to do or something that is necessary for him 
Child :- A person under the age of fourteen 
Evidence:- The facts, signs or objects that make you believe that something is true 
Witness:- Person who sees something happen and is able to describe it to other people 
In conclusion, there is a presumption that everybody has the capacity or incompetent to give evidence in court. This presumption is rebuttable where a person is prevented from understanding questions put to him or giving rational answers to those questions by reason of tender age or disease of the body or mind. If a judge is in the opinion that a child is capable of understanding the nature of an oath and the duty of speaking the truth, he must warn himself so as not to judge based on the uncorroborated evidence of an incompetent child.
