A contingency plan is sometimes referred to as "Plan B" or a backup plan because it can also be used as an alternative action if expected results fail to materialize.
Some common synonyms of contingency are crisis, emergency, exigency, juncture, pinch, straits, and strait. While all these words mean "a critical or crucial time or state of affairs," contingency implies an emergency or exigency that is regarded as possible but uncertain of occurrence.
The average contingency rate falls between 20-40%, with most lawyers charging around 33% to 35% of the total amount recovered in a case. The exact percentage can vary depending on the complexity of the case, the lawyer's experience, and the stage at which the case is resolved.
