What is the test for ineffective assistance in a civil case?

"To show ineffective assistance, defendant must show that 'counsel's performance was deficient, and that the defendant was prejudiced, that is, there is a reasonable probability the outcome would have been different were it not for the deficient performance.' [Citations.] 'A reasonable probability is a probability sufficient to undermine confidence in the outcome.' [Citation.]" (People v. Woodruff (2018) 5 Cal.5th 697, 761-762.)
