A wealthy Iranian businessman is embroiled in a divorce court fight with his estranged Irish wife.
Diplomat's son Mehrdad Radseresht, 72, says Barbara Spain-Radseresht, who is 49 and used to work in the travel industry, agreed to a divorce when they lived in the Middle East more than seven years ago.
Mrs Spain-Radseresht, who comes from Dublin and now lives in London, disputes his claim and says she is entitled to a fair share of a marital fortune running into tens of millions of pounds.
A High Court judge has been asked to make decisions about the validity of the marriage.
Mr Justice Cohen is analysing evidence at a public hearing in the Family Division of the High Court in London.
Mr Radseresht told Mr Justice Cohen they reached a settlement agreement in Dubai in 2009 after Mrs Spain-Radseresht was unfaithful.
She said she found out about the 'alleged Dubai divorce' a year ago when she made a separate divorce application.
