I have seen .50% as an average. Some will split the fee 50/50. I breifly looked into this, then realized I couldn’t find any “true” solicitors in my area outside of the hedgefund world. Seems most of the 3rd party markerts want hedge fund business.

I’m thinking in terms of other financial professionals (accountants, real estate agents) and non-pros as well.  The results of a web search for solicitor disclosure documents indicates a range between 20% and 70% of the advisers fee.
