She is not even sure if she is actually married or not
The OP is married according to Islam. Her marriage is also recognised in the Uk as being legal as her wedding is legal in the UAE if thats where she is. And another good indicator thats she's married is that her husband is her sponsor where she is and to be her sponsor he would have to have submitted an attested copy of their marriage certificate in order to be able to sponsor her.
If I were the OP I'd be hiding under the bed such is the amount of tripe being posted on the thread.
This explains the legalities of the marriage
Is an Islamic Marriage Recognised by UK Law?
For a Muslim couple to enjoy the financial security and the other benefits bestowed by the completion of a civil marriage they must have either married under Sharia law in a country where this type of marriage is recognised by law, or they must get their civil marriage in addition to their Islamic marriage.
We would strongly advice every couple who live in the UK and are married under Sharia law to check whether their marriage is valid and recognised by UK law.
If you are not legally married, you may find yourself in a difficult situation if you were to get divorced or if one partner passes away.
Finding out if Your Sharia Marriage is Valid
Although it is seen as a valid marriage ceremony within Islam, in UK law the Nikah ceremony is only recognised as a religious ceremony, which for that reason carries no legal weight.
Under English law the couples who are only in a Nikah and who did not get a civil marriage are considered to be a “co-habiting couple”. That means that they do not have the same rights as couples in a civil marriage.
The co-habiting couples have therefore less rights regarding pensions and benefits. In the unfortunate event of divorce or death the spouses will also find difficulty.
Getting a Sharia Marriage Overseas
If you had your Nikah abroad; in a country which practices and recognises Sharia Law, your marriage will be recognised by UK law.
As a result, couples who have chosen to get their Nikah in this way will have access to the exact same benefits as couples within a civil marriage.
Getting an Islamic Marriage in the UK
If a couple who is having their Nikah ceremony in the UK wants the same recognition, they need to attend a registry office to obtain a civil marriage in addition to their Nikah.
It is not particularly complex to get your civil marriage in place. You can simply contact your local authority, who can inform you how to undergo your civil marriage ceremony in addition to your Nikah.
