1. The Special Marriage Act supersedes any religious laws that may be in play in this instance, since it is a secular marriage law that enables the registration of marriages between people of different faiths.

2. No, you will not need to change your religion to Islam for this marriage to take place. Even if you decide to go through with the Nikaah ceremony, you will remain Hindu. The Nikaahnama will only have a symbolic value and will not hold any legal power.

3. The Nikaahnama will have no legal standing and is simply ceremonial; thus, it is best to just register the marriage under the Special Marriage Act to avoid any confusion.

1) SMA over rides personal laws 

2) for valid nikhanama it is necessary to convert 

3) if you are not converting to Islam it is basically not valid marriage under Muslim personal law 

Yes you can get married through SMA. Yes SMA will be the legal marriage recognised all other will be treated customary marriage

You can get converted for marriage only if in future you want to commit bigamy.

Yes SMA is good 

Once you get married according to SMA 1954, than custom Muslim Marriage will be just a formalities and its does not mean a conversion of Muslim. 

But after marriage you practice's Muslim custom formalities on daily basis then it will be treated as converted.

But after marriage you practice's Hindu custom formalities on daily basis then it will be not treated as converted.

Better you follow Hindu Religion after marriage on daily basis and stick to SMA always in the life.

1. Whatever ceremonies you may observe post registration of your marriage under SM Act, they will be just formalities to satisfy each other side people. 

Your marriage will be recognized as the one legally valid under special marriage act only. 

2. You may not be permitted to get married under Muslim law,  that is,  Nikah, if you are not converted to Muslim. 

3. Nikah will not happen if you don't get yourself converted. 

You may clarify this.

Yes rest all customary laws only SMA will be a registered legal marriage 

You have not converted into Islam 

you continue to follow Hindu religion 

your marriage is governed by SMA and not Muslim personal law 

The imam cannot perform or witness a Nikah between a Muslim Male and non Muslim female. 

If somebody is doing that then he may face problems in his own community. 

Besides the proposed Nikah is not an ordinary incident in  a Muslim community. 

If you are not willing to get converted then better not to get the Nikah solemnized. 

Instead of flaring up communal issues,  it is advisable that you both may be contended with the marriage solemnized under special marriage act alone. 

You can a decision after analyzing the pros and cons in all aspects and never rush to take a hasty decision. 

Performing Nikaah won't be conversion. Until and unless you accept it and follow the Muslims religion culture and tradition. Here nobody can force you to perform Muslim culture. You are free to live life as per your choice and as per Article 21 (Right to Live) of Indian Constitution Act.

Its totally depends upon you what to remain and which religion to follow.

Take the example of Nargis Dutt she followed Muslim Culture tell her death, however she was married with Hindu religion (Sunil Dutt). 

Dear client,  congratulations on your upcoming wedding! Here are some answers to your questions:

The Special Marriage Act (SMA) is a civil law that governs marriages between individuals of different religions. It allows for individuals of different faiths to register their marriage and have a legally valid marriage certificate. In the case of a Hindu-Muslim marriage, the SMA would be applicable, and any rituals or ceremonies conducted would not supersede the provisions of the SMA. That being said, you are free to have any religious ceremonies you would like, as long as they are conducted after the registration under the SMA.

No, you will not be automatically converted to Islam by signing the Nikahnama. Conversion to Islam is a separate process that involves making a declaration of faith, known as the Shahada, in front of witnesses. If you choose to convert to Islam, it will be a personal decision and not a requirement for the wedding ceremony.

The Nikahnama is a marriage contract that is recognized under Islamic law. It outlines the terms and conditions of the marriage, including the rights and responsibilities of both parties. The Nikahnama is a legally valid document, but its validity may vary depending on the country and the jurisdiction in which it is being used. In India, the SMA registration will be the primary legal document for your marriage, and the Nikahnama will be considered a religious document.

It is important to note that having both the SMA registration and the Nikahnama can provide additional legal and religious recognition to your marriage. However, it is advisable to consult with a lawyer or a religious authority to ensure that all legal and religious requirements are being met.

If you marry under SPECIAL MARRIAGE ACT, there is no requirement for following up of customs. If you follow customs, there will be a custom based requirement either to convert any one religion and not both at the same time. Even though customs are there, nothing prohibits you to following the marriage customs according to your wishes on both religions.

If you want to register your marriage under SMA then you need not to change your religion. SMA allows people of different religion to marry each other without changing their religion. Thus marriage between a Hindu and Muslim can be performed under SMA. There is no value of Nikahnama, between a Hindu and Muslim, in the eyes of Indian law. Nikahnama has validation only if you convert your religion to Muslim before marriage. Changing name Or performing nikahnama doesn't amount to conversion of religion.
