12 months ago, I signed a sublease for an office from someone who had a 3-year commercial lease. He had previously subleased it to another person who walked away from the office leaving all the furniture and paperwork. He would not collect the paperwork and refused to accept any further calls from me. As the paperwork was highly confidential and he wouldn't collect it, ASIC didn't want it, the police didn't want it either, so we shredded some 200 boxes of it. He left all the furniture here and we never heard from him again. Now my landlord has advised me that this person now wants all his furniture back. I had previously been advised that under the law, the furniture was classified as abandoned property after 3 months. Can someone please advise me of where I stand under contract law? Many thanks.
