@ Ruchi,
As per your PM and query I would again suggest you to read with my first post.
In the continuation of my first post I would like to add some more opinions on your further query:
1. FIR is not filed yet as it is in enquiry stage.To know what is the current status you have to send your relative to the concerned police station and recieve the feedback.
2. As per your query the SHO has not recived anything wrong against your brother.So,definately the complaint could not turned into FIR until or unless that SHO is corrupt.
3. I would suggest you to ask your relative and your brother to have good hold with that SHO by going to his chamber and have some favourable words to him.
The benefit is that he will help you if any private case been filed by her and courts again give instructions to the concerned police station of that particular jurisdiction to again enquiry at that time he will be handy.
4. If the matter is simply registerd as GDR then you people can go for Notice bail which gives 3-7 days notice period prior to arrest.
5.Nothing will happen just stay cool and relax as this cases are journey of one's life which will pass in short time.Once you get AB your more than half headache will go away.
Your query related to Alimony and maintenance:
1. Yes she is very much eligible for maintenance if she is not able to maintain her.
2. Maintenance depend on the income of your brother. 25%-40% is an assumption on his final in hand income.(read various topics related to your query on this forum)
3. Merely asking can't be called as claim as she has to fight for her right through court.
4. Alimony is final settlement once decree is passed then one is entitled for that.(meanwhile only interim maintenance is allowed)
5. No multiple of mainetnance can be through by various courts.
6. The more your brother will have liabilities the more less he has to pay her wife.
regards.
