What is the test for clear and convincing evidence in a civil case?

In addition, under the clear and convincing standard, the evidence must create a conviction that the factual contention is "highly probable." Colorado v. New Mexico, 467 U.S. 310, 316 (1984); United States v. Jordan, 256 F.3d 922, 930 (9th Cir. 2001) ("[C]lear and convincing evidence 'indicat[es] that the thing to be proved is highly probable or reasonably certain. This is a greater burden than preponderance of the evidence, . . . but less than evidence beyond a reasonable doubt.'".).
