What if the plaintiffs are making up items and money out of thin air in the estate claim? How do I protect myself?

The plaintiffs are saying there’s thousands of dollars in flatscreen TVs, gold, crystal and furniture that either never existed or didn’t belong to the deceased in the first place. One plaintiff never visited even once in 10 years and the other only visited for a few minutes a few times over those 10 years. I’m the granddaughter of the deceased and they are saying I stole the entire 2 story estate furniture and all when I moved into a friend’s garage with the clothes on my back, my bedroom set and some personal belongings a few that were gifted to me by the deceased years before their death. As there is no massive estate I can’t afford representation and I’m disabled. How do I protect my personal belongs from being claimed as part of the estate?
