Sec. 24. Presumption of consideration. – Every negotiable instrument is deemed prima facie to have been issued for a valuable consideration; and every person whose signature appears thereon to have become a party thereto for value.
Sec. 25. Value, what constitutes. — Value is any consideration sufficient to support a simple contract. An antecedent or pre-existing debt constitutes value; and is deemed such whether the instrument is payable on demand or at a future time.
Sec. 26. What constitutes holder for value. – Where value has at any time been given for the instrument, the holder is deemed a holder for value in respect to all parties who become such prior to that time.
Sec. 27. When lien on instrument constitutes holder for value. — Where the holder has a lien on the instrument arising either from contract or by implication of law, he is deemed a holder for value to the extent of his lien.
Sec. 28. Effect of want of consideration. – Absence or failure of consideration is a matter of defense as against any person not a holder in due course; and partial failure of consideration is a defense pro tanto, whether the failure is an ascertained and liquidated amount or otherwise.
Sec. 29. Liability of accommodation party. – An accommodation party is one who has signed the instrument as maker, drawer, acceptor, or indorser, without receiving value therefor, and for the purpose of lending his name to some other person. Such a person is liable on the instrument to a holder for value, notwithstanding such holder, at the time of taking the instrument, knew him to be only an accommodation party.
