A Landlord and Tenant negotiated a lease agreement of a store premise in a commercial property. The agreement underwent several iterations with massive changes in between each iteration. These earlier drafts of the lease agreement no longer exist.
Prior to signing the final draft of the lease agreement, the Tenant specifically asked the Landlord representative who would be responsible for the removal of fixtures attached to the premise (e.g. wall shelves, etc.). The Landlord representative said that the Tenant would not be responsible for those. This was witnessed by the Tenant's real estate agent.
The lease has now expired. As it turns out, buried deep in the lease agreement, is a clause that specifically states that the Tenant is responsible for the removal of those fixtures (even if the Tenant was not the one who installed those fixtures). The Tenant and the Tenant's real estate agent do not recall this clause in the earlier drafts of the lease agreement. Nonetheless, the Tenant did sign the agreement not knowing that the clause obligating the Tenant to remove the fixtures existed.
Generally speaking, without factoring the country of jurisdiction, what legal arguments does the Tenant have? Assume that both verbal and written agreements are equally enforceable.
