What proof can May Jane use that the two men are dishonest?

May Jane can gather evidence such as text messages or emails that indicate the men made false promises or misrepresented their intentions. Additionally, she can collect eyewitness testimonies or recorded conversations that reveal inconsistencies in their statements. Financial records or contracts that show discrepancies can also serve as proof of their dishonesty. Lastly, any documented history of similar behavior from the men can strengthen her case.
