A Cubic spline interpolation formula is proposed to estimate the quantile function found in the functional form of the Adjusted Lorenz curve proposed by Al-Hussainan (2000) to estimate its theoretical counterpart. This procedure makes, yet, another option of quantile estimation available to the use of the adjusted Lorenz curve
