Dear lawyers My wife left my house with our baby on her own accord and is now claiming maintenance via DV and 125. She has also filed 498A and have trapped my other family members.. I live in UK since 2012 and hold a PR for UK. I am working as an investment banker. Before marriage my wife also used to work in NY and she 's post graduate engineer who had previously worked with renowned engineering firm in America for around 3 years and had worked in India as well. She was earning more than me and has claimed this in 498A FIR as well as in other petitions. We have a 2 years old girl together and she left me for good since boy was 6 months old. She is asking for 4.5 lakh INR per month as maintenance and is claiming I earn 1.5 crore per year! I reckon she is not eligible (being highly and in fact more educated than husband, left matrimonial house on her own accord, deliberately not working to claim hefty maintenance) to claim maintenance and child is a shared responsibility of both the parents. The family case is in madhya pradesh.. Please advise us with interim maintenance ?
