if I make an offer on a property in my small town can I make my offer conditional on the vendor not using a particular law firm. Law firm 'Blogs' behaved improperly towards me and I want to make sure they never make anythng more out of me, directly or indirectly. If law firm 'Blogs' found out I had added that condition is there anything they can do to harm me. If the vendor wanted to use law firm 'Blogs' I would rather not buy the property. Is this defamation?
