A dismemberment abortion—also known as a dilation and evacuation (D&E) abortion—is an abortion in which a person dismembers and extracts the unborn child from the uterus through the use of clamps, grasping forceps, tongs, scissors, or a similar instrument. Some states have passed dismemberment abortion bans. These laws are usually located in a state’s statutes.

Laws vary from state to state and under some state laws the term dismemberment abortion does not include an abortion that uses suction to dismember the body of an unborn child by sucking pieces of the unborn child into a collection container. The term includes a dismemberment abortion that is used to cause the death of an unborn child and in which suction is subsequently used to extract pieces of the unborn child after the unborn child's death.

In Montana, as of the knowledge cutoff in early 2023, there is no specific ban on dismemberment abortions, also known as dilation and evacuation (D&E) abortions. Montana's abortion laws have generally been more permissive compared to some other states, and legislative attempts to restrict or regulate abortion methods like D&E have faced legal challenges. It is important to note that abortion laws are subject to change due to legislative actions and court decisions. Therefore, individuals seeking or providing abortion services in Montana should consult with an attorney to obtain the most current information on the state's abortion regulations and any restrictions that may apply to specific procedures such as D&E abortions.
