When any document written or signed is produced before the court it calls for authentication of the writing. Section 67 requires proof of signature and handwriting of the person alleged to have signed or written the document produced. Mere production of written document is not enough unless the signature and writing are proved. Mere production of paper stating that it was signed by him would not amount to compliance with, when the proof of agreement to sale of goods was in question in this case.
This section lays down that when a document is alleged to be executed, signed or written by certain person it is duty of the person who makes the allegation to prove the fact. But, in Section 67 no particular kind of proof is necessary for the purpose of establishing the fact of execution. In usual modes the handwriting may be proved by circumstantial evidence. The Rule is that the party who exhibits a document, must also prove it that the Document was signed and written by concerned person. In an eviction suit the rent receipts were produced by the tenant having signature of the landlord at the back and the landlord also admitted the fact of his signature.
Where a document is written by one person and signed by another, the handwriting of the former and the signature of the latter have to the proved under section 67 of the Act. If the document is written and signed by the same person (executants) he has to prove his own writing and signature. When there is non-examination of executants of receipt, admissibility of receipts is not proper. In a suit for money on account of sale of goods, the ledgers, challans and corresponding bills have to be forwarded to be in the writing of the person who has written them.
Where a document is purported to have been executed by thumb impression of illiterate person, the person relying upon it has to prove that the document was read over and explained to the executants. The ordinary mode of proving execution is by calling someone who saw the executants write or who knows his handwriting or by comparison of his signature with the signature on other documents written by him. Mere marking of exhibit on a document does not dispense with its proof which is required to be done in accordance with law.

“Section 67 of the Act mandates that the signature and handwriting of a person on a written document can be proved only by examining the person concerned. When the person of very much available and alive, attempt to prove signature of handwriting by examining third person as a witness, would have its own drawback. An inference as provided for in clause (g) of Section 114 would come into play.”
In a suit for eviction on rent receipts produced by tenant, the signature of landlord on back portion of receipt was admitted and the mark exhibit was put on back portion. Rent receipts as a whole can be treated to have been exhibited as admitted documents.
