The phrase "to press charges" means that a victim of a criminal action reports that action to the police, filing a police report so the district attorney or local prosecutor can then prosecute a case. Generally, this causes criminal charges to be brought by the prosecutor against an accused person.
How do you know if someone presses charges against you?
Arrest. The most obvious way to find out if charges are being pressed is when you're arrested, taken to the police station, and booked: your fingerprints are taken, among other requirements. ... In the meantime, the police investigate the circumstances of your arrest and provide any evidence to the prosecutor.
Can someone press charges without proof?
The straight answer is “no”. You cannot be charged and eventually convicted if there are no evidence against you. If you happen to be arrested, detained, and charged then there is most likely a probable cause or a physical evidence that points towards you.
