fake wedding for passport issues

In order to help a girlfriend I met after 3 months of dating, she begged if I would marry to help her immigration status.
The wedding was set up by her and 2 witnesses I never met before were in attendance at a registry office. Registry was some 4-5 hours drive away.
She dully moved in with me as she was having accomodation issues and fell pregnant pretty straight away. The original ''wedding'' was purely for her to gain her full UK residence status. I have emails and pictures to prove that.

The relationship had been rocky at best as we are not compatible living together.
Now fast forward slightly over 3 years down the line and a baby girl in the picture.

We still live together but separate rooms as she wont move out even when I offered cash sum.

I reckon we are cohabitees as the wedding was not suppose to be real in the first place.

What are my options?

Can I :
apply for annulment or
go for divorce

What grounds can I reasonably give for divorce as the wedding was not real to start with.

Can''t comment on legality, though a baby does presume a real marriage. Please don''t put your real name on your posts.

I don''t think you would get anywhere claiming the wedding wasn''t real.

You may not have intended it to be, but you were dating, you moved in together, and you have a child together so presumably you were, at one stage, having a sexual relationship.

The fact that the timing of the marriage was influencd by her immigration does not make the marriage itself any less valid.

Added to which, sham marriages are illegal so if the marriage was a sham then you may well both have committed criminal offences which could result in a prison sentence if you were convicted

Your marriage does not fit any of the criteria for an anullment.

You can of course divorce your wife. She has a right to continue to occupy the family home, justs as you do, until a financial order is made.

well, sequence of event was,my place was already purchased, wedding was done purely for immigration purposes.she moved in 1 month after and baby came after that

The marriage was valid as far as I can see. You were in a relationship before it took place and you''ve had a baby since.

It was a marriage of convenience rather than a sham. As such you need to think about how you are going to both raise your daughter.

She was born here and that will mean Mum will have a right to stay no matter what mud you try and sling at her.

Really sad to hear this story it''s abit like my arranged marriage! You have to be very careful as she will take you to cleaners playing the DV card!
Id try to make it work for kids sake otherwise you will lose assets and she will stop you seeing your kid via the good old family courts who will bend over backwards to support her. Very scary as my life has been ruined and have lost all everything
