My brother (British born citizen) has been diagnosed with schizophrenia since 2006. He is unable to look after himself and make decisions (in a legal capacity).
My parents arranged a marriage with an Indian girl in 2014 who they found through mutual relatives. The girl and her family were fully aware of my brothers mental illness and they had met on several occasions beforehand. The girl had gone as far as to say there isn’t any need to meet my brother as she had left it to destiny - however we insisted they meet. My parents had informed her family that they are looking for someone to look after their son as he requires day-to-day care. The girl obtained her spouse visa mid-2014 and arrived in the UK. She was then granted an extension last year until the end of 2019.
Throughout the years we have come to know that she was purposely not giving my brother his schizophrenia medication (his condition got worse and she made an excuse saying she had been giving him a homeopathic medicine instead). We also found flirtatious messages between her and another guy on her facebook. She would constantly vanish leaving my brother at home without informing us that he was alone (my brother cannot cook for himself).
My mother took my brother and his spouse to India last month to discuss things with her family. The girls parents made it clear that they want my parents to keep their daughter in the UK until she gets her ILR. My mother made it clear that we cannot apply for her ILR as the relationship has broken down.
The girls family then got the police involved in India while my mother and brother were still there. They demanded either 50 lakh rupees (£50,000) or that we agree in writing to ensure she gets her ILR. They said otherwise they’ll file a case (I reckon it will involve a 498a dowry case). My mother and brother have returned to the UK, however the police are harassing my grandad constantly. There are no kids involved and my brother has no assets or earnings and is supported by the government for his care.
I would appreciate any advice on what steps we should take to prevent any cases in India?
Thanks
