Bouvier's Law Dictionary, Revised 6th Ed (1856)
LICENTIA CONCORDANDI, estates, conveyancing, practice. When an action is
brought for the purpose of levying a fine, the defendant, knowing himself to
be in the wrong, is supposed to make overtures of accommodation to the
plaintiff, who accepts them; but having given pledges to prosecute his suit,
applies to the court, upon the return of the writ of covenant, for leave to
make the matter up; this, which is readily granted, is called the, licentia
concordandi. 5 Rep. 39; Cruise, Dig. tit. 35, c. 2, 22.
