I tried to ask this question in r/legal and it derailed to the point that I didn’t get much useful information out of it. Bare bones facts-my daughter is 13, an honor student, extremely hard working and ambitious and involved in many extracurriculars but her number one passion is horses. She has been riding since she was 8 and working at the barn since she was 10. At 12 (at the encouragement and blessing of her mother) she began babysitting and doing minor housesitting during the summer (getting the mail and feeding cats for people on her street who were away). She has regular babysitting gigs now that pay $20 an hour. She has also started giving beginner lessons (under supervision of an adult trainer) and receiving a cut of the lesson fee.

Her mother has now decreed (with zero language in the agreement supporting this) that any money earned by my daughter during her parenting time (ie: my daughter babysits for 4 hours on a Saturday that falls on her weekend) CANNOT be utilized for anything horse related. My ex wants nothing to do with riding and hates that my daughter and I connect deeply over it which is her sole reason for opposing it. Can she mandate this? Is there legal precedent for it?
