§ 3-802 — Effect of Instrument on Obligation for Which It Is Given

Section 3--802. Effect of Instrument on Obligation for Which It Is\n Given.\n (1) Unless otherwise agreed where an instrument is taken for an\nunderlying obligation\n (a) the obligation is pro tanto discharged if a bank is drawer,\n maker or acceptor of the instrument and there is no recourse\n on the instrument against the underlying obligor; and\n (b) in any other case the obligation is suspended pro tanto until\n the instrument is due or if it is payable on demand until its\n presentment. If the instrument is dishonored action may be\n maintained on either the instrument or the obligation;\n discharge of the underlying obligor on the instrument also\n discharges him on the obligation.\n (2) The taking in good faith of a check which is not postdated does\nnot of itself so extend the time on the original obligation as to\ndischarge a surety.\n
