Section 26 in The Negotiable Instruments Act 1881
Title: Capacity to make etc promissory notes etc
Every person capable of contracting, according to the law to which he is subject, may bind himself and be bound by the making, drawing, acceptance, indorsement, delivery and negotiation of a promissory note, bill of exchange or cheque.
Minor.--A minor may draw, indorse, deliver and negotiate such instrument so as to bind all parties except himself.
Nothing herein contained shall be deemed to empower a corporation to make, indorse or accept such instruments except in cases in which, under the law for the time being in force, they are so empowered.
Every person capable of binding himself or of being bound, as mentioned in section 26, may so bind himself or be bound by a duly authorized agent acting in his name.
A general authority to transact business and to receive and discharge debts does not confer upon an agent the power of accepting or indorsing bills of exchange so as to bind his principal.
An authority to draw bills of exchange does not of itself import an authority to indorse.
Title: Liability of agent signing
An agent who signs his name to a promissory note, bill of exchange or cheque without indicating thereon that he signs as agent, or that he does not intend thereby to incur personal responsibility, is liable personally on the instrument, except to those who induced him to sign upon the belief that the principal only would be held liable.
Title: Liability of legal representative signing
A legal representative of a deceased person who signs his name to a promissory note, bill of exchange or cheque is liable personally thereon unless he expressly limits his liability to the extent of the assets received by him as such.
Title: Liability of drawer
The drawer of a bill of exchange or cheque is bound, in case of dishonour by the drawee or acceptor thereof, to compensate the holder, provided due notice of dishonour has been given to, or received by, the drawer as hereinafter provided.
