Negotiable Instruments Act Article 116
If one part of a bill drawn in a set is discharged by payment, the other parts shall cease to be operative, provided that an acceptor who accepts one part of the bill drawn in a set without requiring the other parts to be delivered to them shall remain personally liable for the other parts.If an endorser negotiates two or more parts of a bill drawn in a set to two or more different persons, the endorser shall be liable for any of the parts that have been endorsed by them but not surrendered to them.If a bill drawn in a set is negotiated by endorsement to one person in its entirety, the endorser may, at the time of discharge by payment, request the holder to surrender all parts of the bill, provided that this provision shall not apply if the holder has furnished a guarantee bond or provided security for the bill.
