Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of $D^0$ - $\bar{ D}^0$ mixing and searches for CP violation in two-body $D^0$ decays, a search for CP violation in the charm decays $D^{ \pm} \to K^0_S K^{ \pm}$ and $D^{ \pm}_s \to K^0_S K^{ \pm}$, $K^0_S \pi^{ \pm}$, and a search for direct CP violation in the singly-Cabibbo suppressed $D^{ \pm} \to K^+ K^- \pi^{ \pm}$ decays. These studies are based on the final dataset collected by BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these charm decays. The measured mixing parameter $y_{ CP} = [0.72 \pm 0.18 (stat) \pm 0.12 (syst)]$% excludes the no-mixing null hypothesis with a significance of 3.3$\sigma$.
