Omission Law and Legal Definition

Omission is a failure to carry out or perform an act. Omission is a neglect of duty. Law imposes a duty on every person to take adequate action to prevent a foreseeable injury. In Criminal law, omissions may give rise to lawsuits and will constitute a guilty act if a person breaches his duty. If a person fails to act knowingly that his/her failure would cause a harm or injury to other person(s), then such a failure constitutes an omission. Act of leaving out a word or other language from a contract or any other document is also an omission; however, the document may be reformed if the parties agree that omission was a mutual mistake.
