I'm thinking that that will only work if you all came up with the exact same story that would explain away the fact that you bought the ticket but all the siblings except for you get to share it. That's going to seem really suspicious to the IRS. I think your best bet to stay out of trouble is to split it with them but take your share too. You can always give away your share (up to $5.2 million) and not be penalized. Donate the rest to charities or set up trusts. Win-win.
DV is a cause that means a lot to me so that's why I want to set up and manage a NPO that will assist victims with relocation, job placement, housing, transportation, education, food, clothing and childcare.
My best friend was murdered by her husband who'd never once hit her. She hadn't taken his verbal threats that he would never let her leave him seriously enough. When volunteering some years back, I met a 7 yr old boy who (along with his mother and sisters) was set on fire because his stepfather had had an argument with his mother. He was the only one who survived, but had no ears, nose or fingers afterwards. I also got to know a woman who fled from her husband when she was 39 weeks. She'd been followed across 2 cities so in the end fled the state in the middle of the night with nothing other than what she was wearing.
So many victims with stories that would curl your toes and not enough resources...or mismanaged resources. I have to do this and I will do this. There's a charity/shelter here that provides assistance to the Atlanta-metro areas, and while I can't prove that some of the employees are stealing from the donations, I know enough that I wouldn't give them a penny. Donations of food and clothes, maybe. Monetary donations, never. And that's why I'd need to actually manage a DV foundation and just donate, to ensure the victims who need help actually get it.
