HD 98800 is a quadruple stellar system, with two close stars pairs A and B of the high inclination and eccentricity. A circumbinary disk around the B component was detected. It extends between 1.5 - 2.0 AU and 5.9 - 6.5 AU. In this work we numerically investigate the possibility of the giant planet formation in this complex dynamical environment. We divide our work into two parts. Firstly, we infer the possible stable regions around the B component where particles can survive for 1 Myr. We considered a range of inclinations and eccentricities for the A component. These results are presented in the (a, e) plane for different values of inclination. The results show that in general particles survive between 3 to 9 AU. Now, in the second part, we are working about the possibility of in situ planetary formation in these stable regions. We are numerically investigating the stage of planetary embryo accretion from planetesimals.
