My partner took his life in January and left no will. His mother is now attempting to get legal rights over our assets which are solely in his name. We have 20 years and 5 kids together. She is spreading disgusting lies about me. That I'm drugged up to my eyeballs, an unfit mother, a drunk, that I want our stuff simply to sell it. That my partner told her over the past two years we weren't together. She's managed to tell an enormous amount of people which has stopped them acknowledging my existence. Is there anything I can do?
