Amber Heard could get $20million in a divorce settlement with Johnny Depp after just 15 months of marriage, legal experts claim.

The news comes after she was spotted laughing and joking with her lawyer as she stepped out of court on Saturday where she filed for divorce.

She was photographed with a faint bruise on her face after claiming that Depp domestically abused her, allegedly throwing an iPhone at her after a row apparently over his dying mother.

Heard went public after Depp's lawyers rejected her claims for $50,000 (£34,000) a month in support, $125,000 (£85,000) for her legal fees, their LA penthouse, his Range Rover and custody of their Yorkshire terriers.

The row which allegedly ended with Johnny Depp (pictured performing this weekend) throwing his phone at wife Amber Heard started because his children didn't want her at his dying mother's bedside, a source claims

The news comes after the pair filed for divorce and Amber Heard (pictured) was granted a restraining order against Depp due to domestic abuse claims, which he denies

But the couple do not have a prenup so under California law, she is guaranteed at least one half of however much their combined wealth has increased since they were married.

During that time, Depp was paid $61million (£40million) for his role in Alice Through The Looking Glass and a further $40million (£27million) for starring in Black Mass.

Manhattan-based divorce lawyer Suzanne Bracker told Page Six that Heard should get at least $20million, although explained that income during their marriage would be calculated minus expenses.

'If he made $30 million and he spent $30 million, you're SOL,' she said.

It is claimed that he threw a phone at her during a blazing row, which a friend has claimed was the result of an argument while his mother Betty Sue Palmer (pictured) was on her deathbed

The friend claims that the row erupted because his children from a previous relationship Jack Depp (pictured) and Lily Rose (pictured, left) did not want Heard (centre) at their grandmother's bedside when she was dying

Heard earned $383,000 (£262,000) during the period and cleared $51,000 (£35,000) after expenses, which included nearly $19,000 (£13,000) in business meals.

The row which allegedly ended with Depp throwing an iPhone at Heard started because his children Lily Rose, 17, and Jack, 14 didn't want her at his dying mother, Betty Sue Palmer's bedside, a source claims.

A source told The Sun's Andy Hall: 'Jack and Lily-Rose were certain they didn't want her at Betty Sue's deathbed — and that caused huge friction.

'Johnny told Amber but says she acted ''like a petulant child''. That's when things turned nasty and a huge row erupted.'

Heard was pictured apparently in good spirits as she left her lawyer's building to a waiting limousine.

Heard, who was clasping a laptop computer, arrived at the office at around 3.30pm on Saturday and did not leave until about 7.30pm.

The pair have filed for divorce and she has made sensational claims that she felt 'terrorised' by Depp

In court documents, Heard alleges she 'lived in fear' of Depp during their 15-month marriage and constantly worried he could return to their Los Angeles condo to 'terrorize me physically and emotionally.'

The actress and her lawyer, Samantha Spector, appeared at the Superior Court of California County of Los Angeles on Friday, where she filed for a domestic violence restraining order.

Depp was not in court for the filing. Instead, the star was playing with his band, the Hollywood Vampires, at the Rock in Rio Lisboa festival.

The first incident she documents in the court files is said to have occurred on her 30th birthday at their Broadway home on April 21 this year, when he turned up late 'inebriated and high'.

A long term friend and neighbor of Amber Heard (pictured outside court on Friday) gave evidence to support the young actress's claims that estranged husband Johnny Depp physically and emotionally abused her

A long term friend and neighbor of Heard has given evidence to support the young actress's claims that Depp physically and emotionally abused her.

Raquel Rose Pennington, who has known Heard for 13 years, filed court documents on Friday that claimed she saw Depp 'screaming loudly at her' and wielding a wine bottle 'like a baseball bat'.

A friend gave evidence to support Heard's statement that Depp had become violent after his mother (pictured together) passed

In her account, Pennington says that she received a text from the star asking her to come over, and upon arrival, found Heard 'by the couch, covering her head with her arms and hands, as Johnny was loudly screaming at her'.

The shocking statement continued: 'I ran over and stood in between Johnny and Amber, begging Johnny to stop yelling at her.

'I put my hands out in a defensive manner motioning him to stop. Johnny slapped my hands away and screamed foul obscenities at me.'

Pennington added that the Pirates of the Caribbean star then 'picked up a large bottle of wine and began swinging it like a baseball bat' in order to smash 'everything he could', according to the document seen by The Daily Mirror.

Following the incident she says she brought Heard back to her own home.

Pennington had been at the couple's home Saturday May 21, along with friends Elizabeth Marz and Joshua Drew, when Depp came home 'drunk and high' at around 7.15 pm, according to The Daily Beast.

A representative for Depp said in a statement on Thursday: 'Given the brevity of this marriage and the most recent and tragic loss of his mother, Johnny will not respond to any of the salacious false stories, gossip, misinformation and lies about his personal life.

'Hopefully the dissolution of this short marriage will be resolved quickly.'

First wives club: New documents have revealed Amber Heard (pictured 2011) previously considered herself married to her former partner Tasya Van Ree - the very woman who allegedly Johnny Depp was jealous off

Covered all bases: While gay marriage was not legal at the time, former couple (pictured 2010) did everything that would make them as legally close to married legally changed her name to Amber Van Ree and stated the reason to do so as they were in a 'domestic partnership'

Depp was previously said to be jealous by her close relationship to previous female flames, including Cara Delevingne.

It has since been revealed that Heard entered into a domestic partnership to previous partner Tasya Van Ree, and even changed her name to Amber Van Ree in 2008.

Comedian Doug Stanhope has come to the defense of Johnny Depp, claiming Amber Heard had told the actor she was going to leave him and threatened to lie about him publicly 'in any and every duplicitous way' if he did not agree to her terms.

Stanhope said he was inspired to speak out after watching Depp get 'murdered' on social media after pictures of Heard with a bruise on her face, that she alleged was caused by Depp, appeared online and her allegations became international headlines.

The comedian said the minute he heard the actress' allegations against Deep he 'knew it was bulls***t', he writes in a guest column for The Wrap.
