You'll be fine.
Prudential Ambassador Real Estate
You cannot, legally receive a commission or any portion of a commission under the current lregulations set forth by the Nebraska Real Esrare Commission you must be a licensed agent to obtain any split in the commisiiom. Your Father could try to negotiatiate a portion of what he agreed to pay in some of the costs concessions from his buyer. You are a tenant and not a licensed agent so in your case, the lessee. You have not standing as the owner or negotiator. If, this is the correct question exactlly, Having no other terms spelled out or the contract to refer to I'd also say I may be right but could be wrong.
I get the sense you feel you shoild get a split as the tenant and haven't laid forth the complete information of this transaction. So, I will conclude this answer with; always consult a qualified real estate attorney to be sure.
