At the beginning of each year I tend to re-organize and put my house in order again. I am coming to the end of the year where I now see that the stock business is working for me. I was wondering how the rights to your photos work if you were to die

Do they rights go to your family and can they continue to sell them? I am going to meet with a lawyer in the beginning of the year. Just wanted to know if any of you know. Or if there is something more specific I should do to make sure my family can continue to benefit from all my work.
