The actor was in the middle of a legal divorce case battle with his ex before suddenly agreeing to a $7 million court settlement.
This is due to the latter's decision to donate the $7 million settlement she received from her litigation battle with him.
Heard had reportedly made a promise to give out her court settlement proceeds to two charity organisations, American Civil Liberties Union (AMLU) and the Children's Hospital of Los Angeles.
The amount is to be divided into two, making it a sum of $3.5 million each for the recipients.
A representative of Depp told TMZ that the actor was happy that his ex wife went through with her announcement to make the donations she earlier promised.
"Following Amber Heard's announcement that her divorce settlement was to be divided equally and gifted to Children's Hospital of Los Angeles and the American Civil Liberties Union, two exceptionally deserving and important charities, Johnny Depp has sent the first of multiple installments of those monies to each charity in the name of Amber Heard, which when completed will honor the full amount of Ms. Heard's pledge."
"Ms. Heard's generosity in giving to these wonderful causes is deeply respected", the source concluded.
The pair broke off their marriage following reports of domestic abuse by Johnny Depp.
Heard alleged that some episodes of this happened in the presence of close friends who were ready to testify against the actor in court.
