A Limited Partnership in Luxembourg can take the form of either an SCS (Société en Commandite Simple) or an SCSp (Société en Commandite Spéciale). These structures are commonly used for Alternative Investment Funds (AIFs) and can be set up with or without separate legal personality, depending on whether it's an SCS or an SCSp. An SCS or SCSp is a partnership made up of at least one General Partner (GP), who has unlimited liability and manages the fund, and at least one Limited Partner (LP), whose liability is limited to their investment. These structures are commonly used for Alternative Investment Funds (AIFs) and can be set up with or without separate legal personality, depending on whether it's an SCS or an SCSp.
