Claims for damages in delictual actions must be supported by tangible evidence and proved on a balance of probabilities. Damages cannot be awarded based on speculation, conjecture, or unsubstantiated averments in pleadings alone. Where a plaintiff's own testimony and that of supporting witnesses contradict the pleadings and are internally inconsistent on material facts, the claim must fail. The plaintiff bears the burden of proving each element of the claim, and failure to adduce evidence in support of any material averment is fatal to the claim.
