The term abettor can simply be referred to as someone who pushes, encourages, instigates, or assists someone else in committing a crime. Being an abettor is different from being an accessory because an accessory is present at the time of the crime or offense. An abettor is considered equally guilty as the person who commits the crime.
In most cases, abettors are given the same punishment as the actual person who committed an offense. In simple terms, abettor can be explained as a person who supports a plan of action to commit a crime. It is also known as an accomplice.
