A title defective in form is a title for which some defect appears on the face of the deed. To become the basis of prescription the title must be apparently good and of a kind calculated to induce a belief in the possessor that it is perfect. A title defective in form cannot be the basis of prescription. [Pattison v. Maloney, 38 La. Ann. 885 ]
The following is an example of a case law on title defective in form:
A title defective in form cannot be the basis of prescription. By this the law means a title on the face of which some defect appears, and not one that may prove defective by circumstances, or evidence dehors the instrument. [Land Development Co. v. Schulz, 169 La. 1 (La. 1929)].
