One of the most striking signature of supersymmetric models with electroweak symmetry breaking is the presence of multilepton event topologies in the decay products. In this paper searches are presented for physics beyond the Standard Model (SM) in final states containing charged leptons from proton-antiproton collision data at a center-of-mass energy of 1.96 TeV, collected with Run II CDF and D{O}Detectors in 2002-2006, and corresponding to integrated luminosities of up to 1.1 fb$^{-1}$. In any of the searches no excess of candidates was observed with respect to the SM predictions and limits on masses and production cross-sections are set at the 95 % CL.
