Frequently Asked Questions

Is hiring a private investigator legal in California?

Yes. Hiring a licensed private investigator in California is legal. Investigators can conduct surveillance and gather evidence as long as they follow state and federal laws. At Bonnington PI, we strictly follow California regulations to make sure everything is done properly and legally.

How long does an investigation take?

It depends on the case. Some investigations can be completed in a few days, while others may take several weeks. If your case is a bit more complex, needs surveillance service, and involves legal factors, it’ll take more time. We discuss realistic timelines during your consultation.

What should I prepare before contacting a private investigator?

It helps to have basic details ready, such as names, addresses, photos, vehicle information, timelines, and any relevant documentation. The more accurate information you provide, the more efficient the investigation can be.

Will the evidence you collect be admissible in court?

Yes. At Bonnington PI, we collect and document evidence in accordance with California law to ensure it can be used in court when necessary. Our reports include detailed documentation, photos, video, and timelines to support your case.

Can a private investigator access phone records or text messages?

No. A licensed private investigator cannot legally access someone’s private phone records, text messages, or call logs without a court order. If anyone claims to do so, it’s likely illegal.
