S.C. Code Ann. § 19-1-120: Proving signature of absent witness to bond or note; effect of sworn denial of signature.

The absence of a witness to any bond or note shall not be deemed a good cause by any court of justice for postponing a trial respecting the same, but the signature to such bond or note may be proved by other testimony, unless the defendant in his answer shall swear or affirm, according to the form of his religious profession, that the signature to the bond or note in suit is not his, or in case the defendant or defendants should be executors or administrators unless one of them shall swear or affirm, as aforesaid, in his answer that he has cause to believe the signature to such bond or note is not the testator's or intestate's, as the case may be.
