Jack I'm sorry you didn't understand my English. Once again I do feel you're reading too much into the situation that has you asking the question. Sounds like you want someone to BREAK IT DOWN.
#1- I'll point out, if you're an attorney you should be very very familiar with "every state is different regarding laws ". Real estate is the same way in this case minus any lending situation
#2- no one can give you an exact because you need to follow the law in that state where this so called broker is buying or selling
#3- there's more details I feel we need to answer the question jack. Is this licensed broker selling their own property and running the sale thru another brokerage firm (?) or, theyre using thru own firm ?? So many variables here...
"hypothetically speaking " if this was a sale in my state and I was a licensed broker selling my own house (thru my own firm).... NO I don't have to split anything with anyone. You should also know everything is NEGOTIABLE but if I want a decent buyer and don't wanna piss anyone off then it's best for me to Co op and be willing to pay for my buyer's agent or.....I can just leave that up to the buyer to pay because indeed it is their representation (shrugs)...especially since their agent or broker is Negotiating against me as the seller. If the broker Is selling thru own house and using a different firm to list...then it's up to them...
Also some brokers will still take a commission so it can listed on the HUD statement and or for tax planning purposes
So again, it's all depends. There's no certain answer here. Please refer back to what David said. I hope I made some things clearer
