The amount of evidence needed for a trial depends on the case type, requiring the prosecution to prove guilt beyond a reasonable doubt in criminal cases (a very high standard) versus the plaintiff proving their case by a preponderance of evidence in civil cases (more likely than not). While there's no magic number, sufficient, convincing evidence must be presented to meet these different burdens of proof, covering all elements of the charge or claim.

How much evidence is needed to go to trial?

The burden of proof in a civil case only requires a preponderance of evidence, which is a lower threshold than proof beyond a reasonable doubt. For someone to be charged with a crime, probable cause is required. Criminal cases require a jury to consider statements made for and against the accused.

How much evidence is sufficient?

Can someone be found guilty without evidence?

No, you cannot be convicted without evidence, but "evidence" includes much more than just DNA or video; witness testimony, confessions, and circumstantial evidence (like being near the scene) can be enough for a conviction if they prove guilt "beyond a reasonable doubt". A person can be arrested with less evidence (probable cause), but to be convicted, prosecutors must present strong, credible evidence, often relying on witness statements or other forms of indirect proof when physical evidence is lacking. 

How much evidence do you need to be charged?

To charge someone, authorities need probable cause, a reasonable belief a crime occurred and the person did it, based on facts like witness statements, officer observations, or some physical evidence, but not proof beyond doubt; this is a lower standard than the conviction requirement of proving guilt beyond a reasonable doubt, which requires overwhelming evidence to convince a jury nearly to certainty.

Yes, screenshots of messages can be used as evidence, but they are often considered weak or unreliable on their own because they can be easily edited, cropped, or taken out of context, making them difficult to authenticate; courts prefer original messages with complete metadata (dates, times, sender info) and often require extra proof, like testimony or forensic analysis, to confirm they are genuine.
