SECTION III
On Prescription
1. As the term is used here in moral theology, prescription is a title by which the ownership of property is gained or lost through adverse possession during the time and in the manner laid down by law.
In English law the term prescription is only used with reference to incorporeal hereditaments i.e., rights and profits annexed to or issuing out of land. Of these the chief are advowsons, tithes, commons, ways, watercourses, lights, offices, dignities, franchises, pensions, annuities, and rents. Land and movables cannot be claimed by prescription. However, the Statute of Limitation, 3 & 4 William IV, c. 27, and the Real Property Limitation Act, 1874, have the same practical effect as Prescription Acts, with regard to real property, and it will be convenient to consider them here as such.
The mere possession of property belonging to another even for a lifetime would not of itself transfer the ownership to the possessor. But as it is so much easier to prove possession than ownership, and because those who have been in peaceful possession of property for a long time should, not be liable to be unwarrantably disturbed, and, moreover, in order that owners of property may look after their rights, the legislature has authority to confer a right to property, in consideration of long and peaceable possession. This is what both ecclesiastical and civil laws of prescription do, and these laws avail not only in the external forum, but also in the forum of conscience.
2. In order that ownership of property may be transferred by prescription, certain conditions are requisite either from the nature of the case or by positive law. Theologians usually reckon five such conditions viz.: (a) the property must be such as the law allows to be prescribed; (b) there must be good faith in him who prescribes; (c) consequently there must be some sort of title; (d) there must be possession (e) for the time required by law.
(a) As prescription depends for its validity on positive law, there can be no prescription which the law does not recognize. English law does not recognize any title to movables by pre-
