divorce / ancillary relief

Hi, everybody.
I was not sure in which section to write this message, so chose this one.

I married my wife when I was an asylum seeker and she was an overseas student in London. We are both Russians.
3 years later we separated and at the time we both already had ILR status. Few months later I got a British citizenship and moved to another country.
She now filed for a divorce on the grounds of my unreasonable behaviour. I have no objection to the divorce.
I know that she is also going to file for ancillary relief, i.e. she would like to get some financial compensation from me.

As we were NOT British citizens all the time we lived together in the UK, is she entitled to ancillary relief provisioned in the British law?

I have a decent job which I earned hard way (uni after work, crappy small jobs) and I don't think she has any right to compensation.
I supported her financially when we were together as she was a student and now she has a job of her own, yet, perhaps, less paid. We have no kids.

This question falls more into the family matters, but I am looking for a legitimate way to defend myself. Pls excuse me.

Thanks in advance for your help.

I think she is entitled to ancillary relief under Section 25 of the Matrimonial Causes Act 1973 but have a look and see if you can find any grounds for not giving ancillary relief
