Lease fee

[herme]

My tenant has a buyer for her business and her lease had expired. We were in the process of setting up a new lease as she realised she needs that to sell the business
The agent selling her business has told me I pay a commission on the lease with the new business purchaser
My position is the lease is with the current business owner although not formally signed the intent is there and the new business owner becomes the tenant so no fee for a lease set up to the real estate company as they have sold her business but have done no work for me
Any advice appreciated

Just draft up a new lease with your existing tenant then no fee will be payable.
Is there a ROR?
