§ 601 [Types of Presumptions Defined]

When something is "presumed" in court, it means the law assumes something is true without requiring full proof. But not all presumptions work the same way.

Some presumptions are "conclusive," meaning no one can argue against them, no matter what evidence they have. Others are "rebuttable," meaning the other side can challenge them and try to prove they are wrong.

Rebuttable presumptions come in two types. The first type just requires the other side to bring up some evidence to counter the presumption. The second type puts a heavier burden on the other side, requiring them to actually prove the presumption is wrong. The difference matters because it affects how hard a party has to work to push back against something the law assumes to be true.
