It wont work in your favour, because the court would have decided and ordered this alimony based on her qualification and her ability to work in near future also.
Interim maintenance order remains valid till the permanent maintenance order is given by the court during the divorce.
The maintenance amount is calculated (approximately) by taking into account the total monthly take home income (ie. without tax) of both the spouses. The educational background of the spouses, the number of years of marriage, number of children and child custody are also major factors, which govern the maintenance amount. Maintenance amount can also depend on who well the lawsuit has been fought by the advocates of both parties. The spouse with lesser income or no income can get a maintenance amount, which will make his/her complete earnings (plus maintenance) to be equal to 20% to 30% of the above total monthly income.
For example, if the husband has a take home income of one lac per month and the wife has a take home income of twenty thousand and they have no children in a marriage of 2 years, then the wife can theoretically get Rs.4000 as maintenance. How? The total take home income is one lac and twenty thousand and twenty percent of it comes to Rs.24,000. So, the woman gets Rs.4000 per month, so that her total income (her income+maintenance) becomes Rs.24,000.
If the couple have a child and the woman has the child custody, then she may get a maintenance amount of Rs.10,000 to Rs.16,000 per month so that her total income becomes Rs.30,000 to Rs.36,000 per month. Apart from that there can also be a judicial order defining the details on how the expenses for high studies of the child are shared. If the child decides to stay with the father after the age of 5, then the maintenance amount to the woman gets reduced accordingly.
If a woman’s income is at least half of her husband’s income, then most often she may not get any maintenance.
