WVC 46 - 1 - 309
§46-1-309. 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.
