Varda operates a financial advisory firm that gives advice to small business owners. Varda prepared a loan amortization schedule that assisted Gupta in winning a court judgment against Nguyen for unpaid sums owed him. Now, Nguyen is being sued by another of his creditors. Even though Varda previously was his adversary, Nguyen admired the quality of Varda's work when she helped Gupta. As a result, Nguyen has asked Varda to prepare a loan amortization schedule on his behalf that will assist Nguyen in defeating this other creditor's claim. Does Varda have a conflict of interest?
