👉 Illegitimatisation is a legal concept in the United States, specifically in relation to the process of divorce. It refers to the act of intentionally or unintentionally ending a marriage by filing for divorce under certain circumstances, such as adultery or neglect, without obtaining a court order. This can be done through various means, including using false documents, making false statements, or simply not showing up at court hearings. Illegitimatisation is typically considered illegal and violates the legal rights of the spouses involved.
