We present a method for calculating Lifshitz anomaly coefficients from correlation functions using split dimensional regularization.

This method was used to study the anomaly of a free Lifshitz scalar with a critical exponent z=2 in 2+1 dimensions.

We also show the structure of Ward identities for flat space correlation functions in Lifshitz field theories and discuss the anomaly ambiguity.
