Section 57A-1-309 - Option to accelerate at will. - South Dakota Statutes

57A-1-309. Option to accelerate at will. A term providing that one party or that party's successor in interest may accelerate payment or performance or require collateral or additional collateral "at will" or when the party "deems itself insecure," or words of similar import, means that the party has power to do so only if that party in good faith believes that the prospect of payment or performance is impaired. The burden of establishing lack of good faith is on the party against which the power has been exercised.
