You have enough proofs.

File a police complaint against him in written form to the S.P of your area.

That complaint would be forwarded to the woman police station and matter will be recorded. 

Get the complaint written from an advocate, 

Surely FIR will be registered against him and he will be prosecuted. 

Thanks 

See you can file a police complaint.for bigamy if police fails to take the complaint file a private complaint with the magistrate.

Also file you can file an annulment petition to annul your marriage on ground of his previous marriage and cheating and also can seek maintenance for yourself and the child.

Police is bound to register FIR and investigate. Clear case of cheating and Cohabitation caused by a man deceitfully inducing a belief of lawful marriage.

If police dose not register FIR, complain to commissioner and women cell. 

Pics and declaring wife in documents etc are valid proof.

1. If his previous marriage is not dissolved at time of your marriage then your marriage is null and void and hence you don't have a valid marriage. 

2. However the children born out of this invalid marriage is though illegitimate can inherit the the father. 

3. However you are entitled to maintenance from this person. 

If you want to take action against him, then you can file a Private criminal complaint before the judicial magistrate court under section 494 IPC against him read with section 420 because he has cheated you and married you.

The evidences with you are sufficient to prove his acts of cheating.

You can go for annulment if he has defrauded you about the marriage. You will get the order for annulment frim family court

You can file petition in family court for declaration that marriage is nullity as performed during subsistence of earlier marriage 

2) seek sole custody of your child and maintenance for child 

CONSIDER THIS:
1. All the documents you mentioned does not bear signature of such so called Husband and neither does it documentarily prove anything about such temple marriage.

2. The DNA test of Child would prove that biological father of child is the Husband. BUT here the Husband would say that it was a mutual understanding Live-In-Relationship (which is not illegal as per a Supreme Court judgment)

3. Under the circumstances and since 7 years have gone by, you may claim Maintenance for the Child and settle amicably, more so since conducting any legal proceedings will be difficult, money & time consuming. You have an option of filing a Police FIR against husband, for Cheating, Fraud, Breach of Trust, Mischief etc.... (if that is what you wish)

4. Of course, he can duly divorce his first Wife and THEN duly register your marriage, which will regularize everything. It is a matter of convincing /amicable settlement.

1. The documentary evidence you have is ordinarily sufficient to prove his remarriage to you. You will have to further prove that his first marriage was subsisting on the date of his remarriage with you.

2. You are free to file a criminal case under Section 495 IPC against him and get the FIR registered.

All this is sufficient to implicate him. File a petition in the family court for annulment of marriage. Also file a fir based upon the evidence you have. If the police do not respond then file a complaint case before a magistrate for fraud criminal intimidation and criminal breach of trust and cheating.

Madam, 

It is most sincerely advised that you decide your action and then proceed accordingly. If you wish to proceed against him, you have option of police complaint and prosecute him for criminal offences. 

Dear Madam,

If you are a working woman and can survive without his financial support then you can proceed. First make all arrangements for your livelihood and huge legal expenses. You must fight full time. You may approach High Court and as per the directions of High Court come under obligation to register a case and investigate and your husband will be punished as below.

===========================================================

In case if you want to separate from him, you can file an application seeking declaration of your marriage as Nullity i.e., during subsistence of his earlier marriage he got married you by suppressing the earlier marriage.

you can also file application for custody of  your son and also maintenance for both of you.

Further, if you are interested, you can file criminal complaint on him under Sec.494 / 495 of IPC (Marrying again during life time of wife / husband).

- As per section 17 of Bigamy Act, any marriage between two Hindus solemnized after the commencement of this Act is void if at the date of such marriage either party had a husband or wife living; and the provisions of Sections 494 and 495 of the Indian Penal Code shall apply accordingly.

- Hence, the said marriage with the second wife without getting divorce from the first wife is not valid and attract Bigamy as per law. 

- Further, second marriage with the consent of the first wife is void under section 11 of the Hindu marriage act. Consent of first wife has no value in the eye of the law.

- Since, he married with you without disclosing the true facts of earlier marriage , hence your husband is responsible for the same , and can be convict for the offence of bigamy and cheating. 

- However , as per the Supreme Court,  When a man and a woman live together as husband and wife for a long term, the law will presume that they are legally married unless proved contrary.

- Further, the Protection of Women from Domestic Violence Act 2005 provides for the protection, maintenance and right of palimony to a live-in partner, if she complains.

Respected mam ...

There are two ways first of all you have to settle in your mind whether you want to be with him or take any legal action against him if you want to be with him then make him convince to get divorced with another wife and if you want to take legal action then you have the sufficient mean of evidence that can prove his guilt go fine and file and complaint on that complaint police will lodge FIR under section 494 of IPC for a bike bigamy  then he will be charged you have to produce all the documents first of all in the course of that you have to prove that he is married first and after that he intentionally married with you with intention to cheat youwhile having the first wife then only he will be charged and punished under the laws of IPC.... I am also from gurugram for further assistance you can call me

Thank you

you can file complaint u/s 406 420 and bigamy u/s 494  of ipc. enclose adhaar card and Child birth certificate. 

you may also file for annulment of marriage. 

1. Your marriage is not valid under Hindu Marriage act and considered as null and void due to bigamy of your husband.

2. But your son can claim his rights from his father such as maintenance and school fees and he can also claim share from ancestral property of his father.

3. You should have taken some strong legal actions when it was disclosed that your husband was not divorced at time of marriage. You can file criminal complaint against your husband for bigamy under section 494 IPC.

4. You have enough evidence to prove that your husband  have cheated you.  

Mam first files a case under Domestic violence act and petition under section 125 Cr.P.C  for maintenance. while drafting the petition kindly write and mention all incidents and mention all the relevant facts there. Supreme court also recognises these remedies in case of disputed marriages also which might comes under scanner. even though your husband refuses to be in legal relationship with you still he has to prove all his claims. then you can proceed with the criminal case also under section 156(3) Cr.P.C.

1. As per the information mentioned in the present query, makes it clear that your husband has committed an offence of bigamy for which he would be prosecuted for seven years.
2. I would like to apprise you that the registration of marriage is mandatory, but if you have failed then also the proofs that you are having are sufficient enough that he has married you without giving divorce to his first wife.
3. You may not be getting any right as a first wife of his, but yes surly, your son would get all the rights in the same way like his children from first wife, if any.
4. You should also file a divorce petition along with the alimony and maintenance for your child.
5. His property will be diluted if he happens to go to jail.
