Nevada Jury Instructions
DISPUTABLE PRESUMPTION; JURY QUESTION AS TO BASIC FACTS AND PRESUMED FACT
The law provides for a disputable presumption that (insert disputable presumption).
If you find by a preponderance of the evidence that (insert basic facts), then the disputable presumption operations to shift to (insert name of party against whom presumption is directed) the burden of proving by a preponderance of the other evidence, that (insert nonexistence of presumed fact).
If, on the other hand, you do not find by a preponderance of the evidence that (insert basic facts), then the burden of proving, by a preponderance of the evidence, that (insert existence of presumed fact) remains with (insert name of party attempting to invoke presumption).
