105. The burden of proof in a suit or proceeding lies on that person who would fail if no evidence at all were given on either side.

Illustrations.

(a) A sues B for land of which B is in possession, and which, as A asserts, was left to A by the will of C, B‘s father. If no evidence were given on either side, B would be entitled to retain his possession. Therefore, the burden of proof is on A. 

(b) A sues B for money due on a bond. The execution of the bond is admitted, but B says that it was obtained by fraud, which A denies. If no evidence were given on either side, A would succeed, as the bond is not disputed and the fraud is not proved. Therefore, the burden of proof is on B.
