Hi

Dear Customer, 
Thanks for joining and trusting us, much appreciated!
We would like to inform you that Abu Dhabi Judicial Department is the official authority to issue marriage contracts. Muslims can perform the marriage procedures inside that department, but non-Muslins can perform marriage in the church or their country embassy for the spouse and they have to register the contract in the Judicial Department and the below conditions must be applied:
1. The approval of the wife.
2. Both must be residents in UAE.
3. A certificate of healthy fitness for marriage.
4. Birth Certificates (Original).
5. Passport and valid residence permits' copy.
6. A certificate of marital status of both couples (single, married, divorced), certified (in case outside the country) by the applicant's country's ministry of foreign affairs and the UAE consulate in that country (in case it is inside the country) by the applicant's country's consulate and the UAE ministry of foreign affairs.
When the aforementioned requirements are met, they get submitted with the marriage application at the Abu Dhabi Judicial Department, then the marriage becomes formal in the presence of two witnesses. The marriage certificate is issued within a few days.
The provisions of the legal marriage contract apply to a Muslim if the two parties are Muslims, and if the groom is a Muslim and the bride is from another religion.
A Muslim man may marry a non-Muslim woman.
It is not permissible for a Muslim woman to marry a non-Muslim man without proof of his conversion to Islam. 
The law of the United Arab Emirates also allows for polygamous marriages, provided that justice is provided for in maintenance and good treatment.

1. It is not permissible to marry a woman without her and her guardian consent.
2. The legal age for marriage is 18 years. Otherwise, the judge's approval is required.
