Gabriel Aubry wants to ''substantially increase'' the monthly payments he receives from Halle Berry.
The model is currently embroiled in a bitter battle with the actress over the custody of their four-year-old daughter Nahla and was in court today (03.05,12) with his ex-girlfriend to ask for a raise in the amount of money she pays to him, according to RadarOnline.
However, he did not get the chance to have his case heard as the judge granted a continuance.
Halle wants to move to France with Nahla and her fiance Olivier Martinez because of concerns about the paparazzi and the child's safety, but her ex is trying to stop her from re-locating because he believes he won't get to see his daughter.
It was previously revealed Gabriel - who split from Halle in 2010 after five years together - was worried Oliver is planning to adopt Nahla.
A source said: ''Gabriel fears that Halle's ultimate plan is to get him out of his daughter's life, permanently.
''He believes the plan is for Halle to move to France with Nahla and then have Olivier adopt her as his own. She wants a 'fresh start' apparently.''
''Gabe will fight tooth and nail to retain custody of Nahla. He loves that little girl and is determined to always be a part of her life and always be her father.
''Just because Halle is through with him doesn't mean she can shut him out of her daughter's life too. Gabe may not have Halle's money or power but he will not just lie down and take it.''
