The quantum of alimony normally will be calculated on your net salary as per following formula. See that your net home drawing salary is very less.
HOW TO CALCULATE ALIMONY
My answers as follows.
1)what is the max alimony I can claim from him?
Ans: The quantum of maintence must be based of SC judgment which says 25% of salary must be maintenance. Thus it must be calculated as follows
Salary Rs.2 lakhs per month
25% comes to Rs.50,000 multiplied by 12 Months = Rs.6 lakhs per year.
If you live for another 20 years it comes to Rs.6 lakhs multiplied by 20 = Rs. 1crore 20 lakhs.
You get total compensation of Rs.1 Crore Rs.20 lakhs.
2)can I ask for a property?
