Tennessee State Code TCA 39-13-606 allows for a vehicle to be tracked if all registered owners of the vehicle have consented. Many times a client is not able to legally track a spouse or partner’s vehicle. If you are looking for a way to legally track someone there are a few options. Currently there are no laws in place to address tracking a cell phone with an app. Iphone has a FindAFriend app that can be turned on and off by user at anytime. We have found FindAFriend is not accurate, many times it will show the phone up to a mile away from its actual location. If you are experiencing this flaw in the system, refresh the app, maybe see if the person will text you back so the app can pick up a more accurate location. Find My IPhone is app that have found to be accurate. However, a person must have access to the password on someone’s ICloud account to use Find My IPhone. Another option is to track your own vehicle then trade vehicles with your partner. We had one case where the husband traded vehicles with his wife telling her he was going out of town. He told his wife that since her car was better on gas he preferred taking her car. Also he could make sure it was driving correctly and get an oil change. Further, at the appropriate time, the husband called his brother, had his brother three way call the wife, making the wife think her husband was far away at his brothers’s house. As soon as she thought her husband was far away she drove to her paramour’s residence. She was very shocked when she returned home to find her husband waiting with a video of her activities in hand. The penalty for tracking someone’s vehicle is pretty stiff so don’t track it unless you own it.
