Hi Deborah
So technically you are on the hook for the next 10 years at £13,500 = £135,000. Did you say that your daughter was a former business partner? If so, is she (or anyone else for that matter) jointly liable for the lease?
The point about mitigating losses, is that your landlord will need to relet the premises, and when he does the rental income he will receive will be deducted from his claim against you - this will be academic if you go bankrupt. As there seems little sign of him letting the premises in the near future, he is likely to start pursuing you. I also am assuming that there is no prospect for you selling the business and transferring the lease to a new owner?
You could ask the landlord to accept a surrender of the lease, and write off the balance owing, but I think that you have little chance of success. Also beware if there are stocks and fixtures and fittings which belong to you on site, the landlord also has the right to distrain over the assets in lieu of his unpaid rent.
If you have nothing to lose by going bankrupt, and the landlord exerts pressure on you to pay, I would go down that route to bring finality to this issue - but do talk things through with your own IP who will have a much better handle on the issues involved with your case than me.
