We investigate the effects of dynamical interactions in systems containing multiple planets after

the initial stage of planet formation was complete. In particular we focus on the change in the 

planets' orbital parameters due to planet-planet scattering and secular perturbations. During the

period of dynamical activity we show how planets are ejected from their systems and how their 

inclination and eccentricity can grow even when assuming very low starting values. Our 

results are based on over 1000 numerical integrations of ensembles of randomly constructed planetary

systems, both in a single or binary system, each lasting 100 Myr
