A friend of my wife and I took engagement and wedding pictures for us as a wedding gift. After our wedding she and my wife had a falling out and the friend says we can't have the pictures. She wanted us to pay for them and sign a contract we said no and asked her not to contact us anymore. Since then we have not contacted her but she has been texting us threatening to take us to court to try and make us pay for her time and film. After we did not respond she texted and said that she is going to sell the pictures. What should we do? Can she sell pictures of us without our permission? If not how do we stop her from doing it?
