Can screenshots of messages be used as evidence?
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.
What are the 4 types of evidence?

What four things must be proven by a plaintiff in order to establish negligence?
To prove negligence in court, a plaintiff must establish four key elements: Duty of Care (the defendant owed a legal duty to the plaintiff), Breach of Duty (the defendant failed to meet that duty), Causation (the breach directly caused the injury), and Damages (the plaintiff suffered actual harm or loss). Without proving all four, a negligence claim will likely fail.
How to win a court case as a plaintiff?

Are civil cases easier to win?
Yes, civil cases are generally considered "easier" to win than criminal cases because they have a much lower burden of proof, requiring only a "preponderance of the evidence" (more likely than not, or 51%) compared to the "beyond a reasonable doubt" standard in criminal law, meaning less certainty is needed to win. However, "easier" is relative; civil cases still demand strong evidence and preparation, with success rates varying significantly by case type (e.g., car accidents are higher than medical malpractice).
Who beats the burden of proof?
In most cases, the burden of proof rests solely on the prosecution, negating the need for a defense of this kind. However, when exceptions arise and the burden of proof has been shifted to the defendant, they are required to establish a defense that bears an "air of reality".
What is clear and convincing evidence?
