Criminal Liability for Leaving a Store With a Found Phone

Attorney Answer

Walking out of a store with a phone you found, with no intent to keep it, is not theft — the intent element is the whole case, and forgetting to hand it in does not establish it.

California's theft statute punishes taking the personal property of another, but the statute itself does not spell out the mental state. California case law supplies it, and it requires an intent to deprive the owner permanently, or for so extended a period as to deprive the owner of a major portion of the property's value or enjoyment. If you meant to hand the phone to customer service and simply forgot while you kept shopping, that is the opposite of the intent the law requires.

There is also a statute aimed at exactly this situation. Someone who finds lost property under circumstances giving them knowledge of, or a means of inquiry as to, the true owner, and who appropriates it to their own use without first making reasonable and just efforts to find the owner and restore the property, is guilty of theft. Read the other way, that is the roadmap for your defense: prompt, good-faith efforts to get the property back to its owner are what the statute asks for.

On the facts you describe — never using or altering the phone, being contacted within about half an hour, and returning it — the evidence points toward a lack of criminal intent rather than toward a violation. Whether a report becomes a case is a separate question decided by police and the district attorney based on all the evidence, and many reports never result in charges.

What you can do

1. If contacted by law enforcement, stay calm and cooperative, but do not give a statement about your intent without speaking to a criminal defense attorney first.

2. Do not write out your own account of what happened. Notes you create yourself are not protected by attorney-client privilege, can be seized or subpoenaed, and can be used to impeach you if your testimony later differs. Instead preserve the records that already exist — texts, call logs, emails, receipts, photos and location history — along with the names and contact details of any witnesses, and give your account to your attorney verbally.

3. Preserve anything showing you never used or accessed the phone.

4. If store surveillance footage exists, note that it may show you carrying the phone openly rather than concealing it, which supports your account.

5. Speak with a California criminal defense attorney promptly if a report has been filed, even though no charges exist yet.
