Halle Berry's proposed move to France would damage the relationship between her four-year-old daughter, Nahla, and the girl's father, Gabriel Aubry, according to a child custody evaluation.

Halle, 45, wants to relocate to France with their child and her fiancé, Olivier Martinez, because of their better child privacy laws. However, Gabriel is fighting against the decision and a custody trial is scheduled to begin in the next few weeks.

"The report concluded that Gabriel's relationship with Nahla would clearly change drastically if she moves to France. Gabriel plays a very active role in Nahla's life and has been a doting and loving father and that would obviously change if she moved to France. The report notes that Gabriel takes Nahla to and from her preschool and spends as much time as possible with her under terms of the current custody agreement. The bottom line is that the proposed move to France would essentially cut Gabriel out of Nahla's life and the child psychologist determined that wasn't in the little girl's best interest. However, this is just a report, it will be up to a judge to ultimately decide if Halle will be allowed to move to France with Nahla," a source said.

Halle and Gabriel split in 2010 after five years together. Her engagement to Olivier will make the third wedding for the actress and Gabriel's lawyers are using her two previous marriages to prove moving isn't best for Nahla.
