I intend to sell a second-hand gaming laptop on Gumtree soon; it'll be my first time selling an item online, so I've done all the research I could to prepare for this.
At first, I was convinced that I didn't need a bill of sale for an item as small as a laptop; but then I realized I'd need one if I intend to transfer the remaining manufacturer's warranty to the buyer (I'd really rather not have to do this since it's too much hassle).
Am I legally bound to transfer the remaining manufacturer's warranty to the buyer?; or can I just list in the description of the laptop "-Warranty not included" and be rid of all the extra hassle? (I live in the UK if that's of any relevance :D)
