We investigate the possibility to identify the nature of spin of exotic charged particles at the future $e^+e^-$ collider in $l^\pm+2j+MET$ final state choosing IDM and MSSM as examples for the new physics models with scalar and fermionic exotic charged particles, respectively. We choose four benchmarks for the mass parameters โ€ฆ
