Help a Single Mother

Please help my sister pay her mortgage so she doesn't lose her house. She has two beautiful kids that are in the middle of a mess. Her husband cancelled the mortgage payments and stole all of their money including her own personal stash she had been saving and ran. He has been arrested for abuse but none of the money has been recovered and she has $200 left in her account to raise two children and an $1800 mortgage due on the 15th. I wish I had the funds to help her myself but unfortunately I don't. I don't want her to lose her house to the bank so anything helps. Even if you can't donate money maybe you can donate time or advice. She needs her roof completed since her husband left half of it incomplete or if you know any advocates or lawyers that could work pro bono. Please message me if so.
