First I will say this is a very sensitive issue and since it's a matter of misconception, the harder you try to convince the woman the more she will think you and your brother are trying to play her.

Way forward
Yes you are right to want to confront her. Try pay them a visit. Sit the two of them down and sincerely tell her about how you paid your money put every small and minute details like how you paid, where you met the person you paid to what he said and so on. Since a true story will always carry more water than a cooked lie.

Tell her that you could have kept quiet and let her accuse her husband wrongly but you just have to say something to save their marriage.
Besides let her know it pains you that she doesn't trust her husband

Lastly tell her if she doesn't believe, she is free to do whatever she can to find out the truth. You have spoken your mind.
Note: Do not quarrel or show any form of anger while talking to her.
- This issue goes a long way in showing your brother can't control his home infact the wife seems to be the head and i if he doesn't man up his wife will wrap him around her fingers. But don't tell your brother this as he might take it in the negative sense.
