When the bill was at first introduced in Rajya Sabha, several members raised the objections and sought amendments and hence, the bill was referred to select committee and after taking into various view points the select committee made certain amendments and it was approved by the cabinet and after that it was put for voting before Rajya Sabha in current session and it passed it. After formality of putting it in Lok Sabha, as rumours are going on that it would be put in the current session itself, which is extended till 6th of September, 2013, the bill will be passed and be sent to presidential assent. In a nutshell, the remaining acts to bring this bill into Act are mere formalities and so there will be no impediments and no further amendments to the bill passed by Rajya Sabha.
Now, as the divorce case was dismissed in the trial court, after the Act is passed, your husband will be having two options and first to confine his argments in the appeal on the grounds he relied on in the trial court or secondly, seek the permission of the court to get divorce on the ground of "IRBM". Once the Act is passed, when the courts find that the traditional grounds, i.e., cruelty, desertion etc. are not proved in divorce case, if the parties are living apart for more than 3 years, the court itself may offer the choice of divorce on IRBM grounds. Once divorce on the ground of IRBM is on the cards, automatically the compensation laid down in that particular section will be applicable. Over and above, in my opinion, once the Act is passed, the courts start to give liberal interpretation to Section 25 of the Act (Permanent Alimony) and the property will be given to the wife in sync with the latest amendment, even though the divorce is granted on the traditional ground. That is why, in my opinion, if your husband gets the divorce in the appeal on the traditional grounds he relied on in trial court or failing which, if he resorts to IRBM ground, you can insist and will get property share and compensation in accordance with the amendment Act.
