Let (X_{i},Y_{i})‎, i=1,2,...,n be independent and identically‎ ‎distributed random variables from continuous bivariate distribution function F(x,y)‎. If X_{(r:n)} denotes the rth‎- ‎order statistic‎, ‎then the $Y$'s associated with‎ ‎X_{(r:n)} denoted by Y_{[r:n]} is called the concomitant of the rth‎- ‎order statistic‎. ‎In this paper‎, ‎we propose a measure of inaccuracy for concomitants of order statistics and record values in Morgenstern family‎. ‎We also study some results of cumulative inaccuracy for concomitants of order statistics and record values.
