0130_halle_INF Halle Berry just arrived at the L.A. County Courthouse ... ready to do battle with baby daddy Gabriel Aubry.

Halle is trying to get a restraining order ... prohibiting Gabriel from having any contact with Nahla until the child endangerment investigation targeting him is resolved.

Sources tell us ... it's possible Halle will be required to testify today. Gabriel is trying to get an order firing the nanny ... something Halle doesn't want.
