Starting this week I have my niece living with me and watching my son. My brother and sis-in-law just got divorce in May. She took him to the cleaners. He is now living back with our mom. My ex sis-in-law called me yesterday and asked that I give her daughters money to her because she needs to help pay the bills. My niece is only 15 years old. I am so angry about this. My sister in law took the buy out from Chrysler last year and pissed it all away. My brother did not get a dime. She said it was her money. Greed is what broke up the marriage. Now he is paying child support and alimony. She also got the house without paying him anything for it.  His kids are going to our mom's house and asking for food. Saying that their mom can not affords to buy food. Isn't that what child support is for. She is getting money from my brother but, she is so bad with money.  I don't think this is fair to take money from her kids. I wish my brother would grow a pair of balls and tell her if she can't take of the kids he will take her to court.  I don't want to get in the middle of this but my niece is so upset that she has to give her money to her mom to help support the family. I do like my sis-in-law but I don't like what she has become. She is the type when she gets upset she goes out  and buys a new outfit or shoes. I don't think it is right to have your kids financially support you at the age of 15 because you can't manage money. Can I get some advice please.
