Antonyms for the phrase "involve litigation" include "avoid dispute," "resolve peacefully," "reach a compromise," "settle amicably," "negotiate a settlement," and "agree out of court." When parties involved in a legal dispute seek to avoid prolonged and expensive litigation, they can explore alternative methods of dispute resolution, such as negotiation, mediation, or arbitration. These methods offer a more collaborative, less adversarial approach to resolving conflicts. While some disputes may require legal proceedings to reach a resolution, seeking alternative methods can often save time, money, and stress, and lead to a more satisfactory outcome for all parties involved.
