Back when I was practicing law, ignoring my health, and always exhausted, there were oh so many things to think about. One of them was referral fees.
Of course the Law Society has rules about referral fees, as they should. (There are a whole bunch of other things that they have rules about which they should not be involved in, but I will save my rant about that for another day.)
In our firm, we kept our rules about referral fees a whole lot simpler than the Law Society rules. We did not pay referral fees and we did not accept referral fees.
