Here's a plain English summary:
In a civil lawsuit, sometimes the law assumes something is true unless someone proves otherwise. This is called a presumption. If a presumption works against you, you have to bring in some evidence to challenge it. If you don't, the court will just accept the presumption as fact.
But there's an important limit here. Even though you have to produce evidence to fight the presumption, you don't automatically take on the full job of proving your case. The person who originally had to prove their side of the case still has that job. Producing evidence to challenge a presumption is a smaller task than proving your whole case.
Also, a presumption doesn't just disappear once someone brings in evidence against it. It stays in the case and the jury or judge can still consider it, weighing it alongside the new evidence. So even after both sides present their evidence, the presumption is still part of what gets thought about when deciding the outcome.
