I need a lawyer

I need to file an application to the First Tier Tribunal for the exercising of our Right of First Refusal under s12B Landlord and Tenant Act 1987. S12B Notice has been served but the new Purchaser has not responded. We need to make the application under s13 LTA 1987 before 1 October 2021 to avoid the new landlord serving an s17(3) LTA 1987 Notice. The lawyer needs to help us draft the Application, get the Application filed in Manchester FTT.
