Have recently become friends with a mum from dcs school. She has a 6 year old and a newborn with her dp. They have been together on and off for ten years. He lives with his mum, she says he can't be relied on to contribute to her household (drinks excessively and unreliability self-employed) and they are better off this way. He visits regularly to see the children, they do the school run together etc. He stays over 1-3 nights per week. He has a car and a work van and she uses the car to take their son to school while he uses the van so it's parked at her house a lot but as the neighbors see her using it everyday I presume they just think it's hers.
She refuses to live with him until he has a steady job and quits drinking but seeing as it's been 6 years since their ds was born I worry for her that they're pushing their luck by living like this and claiming benefits and that ultimately it'll be her and the children that suffer. Aibu to ask if anyone has experience/knows the criteria when considering benefit fraud? I would hate to see her get in trouble.
