I have a new one for ya!
Two step daughters live with us during school & mom during holidays & summer. They have cell phones paid for by their Mother's Mother. In the past when the kids get bad grades or into other trouble, they get restricted from their phones & other electronics (depending on how severe).
Last week YSD got caught by her
DH texting at school. He told her not to do it again, or he would now allow her to take the phone to school. A few hours later she did it again. She was texting
BM from school telling her to check her out early (it was Friday of BM's weekend).
When DH picked up the kids Monday (holiday weekend) he was told that if he prevented YSD from taking phone to school, Grandmother would report him as having stolen property.
When he got home he called the Sheriffs department & spoke with an officer. Yes indeed charges could be filed against him for taking the phone, even it he just made her leave it home. He would be depriving the authorized user of use.
The only way out would be to return the phone to the Grandmother. But she would just take it to YSD at school, so we would have to repeatedly return it to her (if we even knew YSD had it, she could hide it).
We will be going to court in April, so DH plans to bring it up, but what a mess!
