Different LHC searches have been proposed in order to look for Physics Beyond-the Standard Model (BSM) and in particular more than one half of these searches are devoted to Supersymmetry (SUSY). One of the most interesting searches is the one looking for the neutralino/chargino sector. This is because in their production and subsequent decay, they present a final state in which there are a defined number of leptons and missing transverse energy, making the signal clean and easy to target.  However, we know that there is a large plethora of different realisations of SUSY models in the market, in which the properties of the neutralino/chargino sector are totally different from the usual ones. In this case, their search using the leptonic signals is no longer efficient and one should study which other searches could be useful in each case. Nevertheless this does not mean that multilepton searches are not as effective as we can think. Using the same reasoning, there could be other sectors in the different SUSY models that once their properties are different from the usual ones, will produce a signal that would consist of leptons and missing transverse energy. In this talk I will discuss how different SUSY models can develop different properties in the neutralino/chargino sector and study which searches become more efficient in these cases. I will focus on the neutralino/chargino sector of General Gauge Mediation and stealth SUSY models. Then I will go through the case in which the multilepton searches can be useful applied to the case of light staus within the context of RpV-SUSY.
