Hello and thanks for using Just Answer.
I am Al and am happy to assist you with your enquiry.
Any Buyer's Solicitor will ask your SOlicitor to obtain replies to standard Leasehold enquiries, and one of these questions asks "is there any current dispute between the Freeholder and the Tenant?"
So, on the basis that the Freeholder or the Managing Agents are bound to disclose any issue anyway, you may as well give as much information as you can on the PIF.
I hope this assists.
