My Mom recently passed away and my brother, sister and I will be recieving her retirement pention soon. I'm pretty sure I'm her beneficiary so I will be the one responsible for dividing it up. My brother and I agree to split it up 3 ways. My sister however thinks we should include her 2 kids and her grandchild - and not my step-son. (her 23 year old son lived with my Mom and somewhat watched over her but only paid 200 a month rent) So she thinks he needs to be included one way or the other mostly for that reason. What is fair here? I'm so confused and don't know what to do. I dont want to fight with anyone. Can you please tell me which is the proper way? If I'm the beneficiary can I tell the company I don't want to be and to just divide it up however they would automatically?
