These Introducer, Fee and Commission Agreements are designed to protect the "introducing" party and help ensure that they get paid for the services provided. Whether or not you are introducing business or potential business to known or new contacts it is always advisable to ensure that the "introduction" relationship is properly documented.
The role of the "middleman" is often underestimated and abused once parties have been introduced, so the importance of documenting the relationship at the outset should provide the parties with a clear definition of their obligations and untertakings.
Having an Introducer, Fee or Commission Agreement in place will also facilitate the negotiation of key variables such as referral fees and commission rates, and also competition, confidentiality, non-circumvention and non-solicitation issues.
