The brother of a late property tycoon who lost a bitter inheritance battle with his yoga teacher widow has been handed a £490,000 court bill.

Gabriela Teixeira, 51, and her brother-in-law Amir Moaven were locked in a High Court dispute over Abbas Moaven's £5million fortune.  

Ms Teixeira, a birth doula and yoga teacher, had been expecting to inherit millions when her wealthy investor husband of ten years died in 2012, aged 45. 

The mother-of-two was shocked to discover that he had signed legal documents weeks before his death to declare four properties - at the time worth over £3million - were actually shared with his mother and Amir. 

But 14 years after he died, Ms Teixeira and her two children - Elis and Aryan - have won a court battle after they successfully argued that their entire value should be included in her husband's estate.

Her victory has boosted her inheritance to as much as £5m while Amir has been found liable to pay the £490,000 legal costs of the case.

High Court judge, Deputy Master Timothy Bowles, found that the documents Abbas signed declaring the properties were not entirely his were a 'sham,' designed to prevent his widow from accessing most of his wealth after he died and that the story behind them being drawn up was a 'fiction'.

The judge also found that Abbas' accountant Behzad Faiz and conveyancing solicitor Marios Robert Pittalis are also jointly responsible alongside Amir to pay £473,000 of the bill, having been 'complicit' in the creation of the 'sham' documents.

Amir also has to pay an extra £17,000. 

Abbas, and his brother, Amir, moved to the UK from Iran in 1982 to live with their father and later began a west London clothing shop called Homeboy together.

They then moved into the then burgeoning mobile phone market in the mid-1990s and later restaurants, while also buying up a series of properties around the capital.

Ms Teixeira and Abbas met at his then restaurant, The Gate, close to Notting Hill Gate Station, and began dating, eventually marrying.

Abbas was diagnosed with cancer in 2009 and died in May 2012, with his last will leaving his estate in third shares to his widow and two children.

But the court heard the estate was 'substantially diminished' because, only weeks before he died and while in hospital in April 2012, Abbas had signed fake trust documents, declaring that four properties in his name were actually owned in one-third shares by himself, his brother Amir and their mother, Nazemi Tehran, who has since died.

Ms Teixeira's barrister, Alexander Learmonth KC, argued that the documents were 'obviously shams,' designed by Abbas to prevent his wife or creditors from making a claim to most of his assets after his death.

He pointed to an attendance note from a meeting between Abbas' solicitor Mr Pittalis and Amir, when Abbas was 'seriously unwell' at home and his brother was seeking to 'regularise their affairs.'

The lawyers' note stated: 'His concern was what would happen if Abbas passed away and his wife disappeared with the two children to Brazil. How could they prevent this, and how could they prevent her from having access to the funds from the property assets?'

A subsequent note following another meeting added: 'Amir confirmed his main intention was to secure Abbas' children's welfare because he was certain that any assets passed over to Abbas' wife would be dissipated.'

Mr Learmonth told the judge that Ms Teixeira was anxious to restore the properties to the estate and get her inheritance, adding: 'She is unable to sustain the lifestyle she enjoyed during Abbas' lifetime, while he was still well, on her income working as a doula.

'It is deeply unsatisfactory that 14 years later, Gabriela and her two children - now grown from infancy to adulthood - have still not been able to obtain a proper account of Abbas' estate, let alone to receive their inheritance.'

Allowing the claim in May, the judge dismissed arguments by Amir, now 56, that the four properties - which include Ms Teixeira's former homes in Queen's Gate, Holland Park and Brasenose House, Kensington, as well as rental property in Maida Hill - were only ever put into Abbas' name for 'cultural reasons' because he was the elder brother.

'Contrary to the false narrative set out in the recitals to declarations of trust, the properties are not and never have been held on the informal trusts alleged in those recitals and in the declarations of trust,' he said.

'The extrinsic evidence fully supports the view that Abbas has always been the legal and beneficial owner of the properties.'

Going on this week to order Amir, Mr Pittalis and Mr Faiz to foot the bill for the court fight, the judge said the declarations of trust were 'no more than deceitful forms of words, or "pieces of paper", designed to convey to those to whom they were deployed that Abbas' estate was very much smaller than it truly was.
