Can I press charges/sue someone for recording me without my consent?

Assuming that the issue of proof can be met, you can potentially bring both criminal charges and a civil lawsuit in this case. Of course, you may want to double check that your state is an all-party consent state. Even if it's a private conversation, you have to consider a reasonable expectation of privacy. How many people were in that area with you?

To illegally record someone without their consent is a crime in California, as well as a personal injury for which you can sue for money damages. But if you were recorded in a public or semi-public place like a street or restaurant, then you would be probably be deemed to not have had a "reasonable expectation of privacy" (i.e. that no one was listening in or overheard the conversation).

What Are the Penalties for Illegal Recording?

The exact penalties vary by state. In a 2-party consent state, offenders could face five years in jail or around $500 in fines. This is true whether it involves video recordings or phone conversations. It's seen as an invasion of privacy.

If it's a private party recording your conversation, it's also treated differently than if the recorder is a government agent. A police agent may need to follow wiretapping law and get a warrant. The fines could also be larger. If you're in a state where only one party has to consent, this doesn't apply unless there was some other measurable harm.

Keep in mind that a 2-party consent state isn't referring to the numbers. If you have 3 or 4 people in the recording, all parties have to consent. In Oregon, while in-person recordings require everyone's consent, Oregon is among one-party consent states for telephone conversations.

Should You Sue for Illegal Recording of Oral Communications?

A lot of how you move forward will depend on the case. What was the recorder's intent in recording your conversation? Was measurable harm done? Were you in a public place or a private area where you could expect some privacy? If you're talking to law enforcement officials, did they have authority to record you? 

If you take a telemarketing call or participate in certain events, they will tell you you're being recorded. If you stay in the conversation, you are giving your implicit consent. 

At this point, you should consult directly with an attorney in your area. It sounds like you were caught up in secret recordings you did not authorize when you may have had a reasonable expectation of privacy. You can discuss actual damages and how private laws apply to your case. After you go over all of the details of your case, they can best advise you further. An experienced attorney can assess criminal penalties and consent requirements to offer legal advice.
