The former couple struck a deal to end its bitter three-month divorce battle in August (16), after Heard accused Depp of verbally and physically abusing her throughout their 15-month marriage.

The 30-year-old subsequently announced plans to split the money he agreed to hand over equally between two charities - the American Civil Liberties Union's (ACLU) domestic violence unit and the Children's Hospital of Los Angeles - but last month (Nov16), it was revealed organisation officials had yet to receive any cash after an initial $200,000 (£161,000) cheque, which was sent directly by the Pirates of the Caribbean actor.

Heard's attorney, Pierce O'Donnell, claimed the paperwork set to finalise the divorce was due to be signed by both parties by 4 December (16), allowing the rest of the money to be paid to the charities, but it appears there has been a hold up in the legal process.

On Wednesday (14Dec16), The Danish Girl star filed a Request for Order at Los Angeles Superior Court, and asked a judge to ensure the agreement is enforced.

In the documents, obtained by, Heard's attorney alleges Depp has ignored the court-ordered payment deadline, as well as other mandates regarding the division of personal property, the shipment of belongings from his island home in the Bahamas, and the transfer of a Range Rover into the actress' name, among other issues.

Heard also wants Depp to pay her legal fees of $35,435 (£28,530) in full.

The stars' divorce settlement required Depp to hand over the remainder of the $7 million over the next 12 months, with Heard expected to complete the transfer of cash to her chosen charities by the end of 2018.

Depp's representative has yet to comment on the latest development in the former couple's divorce.
