How to write sponsored ex-wife's name on new wife's PR application

[thaivan]

Almost 20 years ago, I sponsored my wife for PR.
About 10 years later, we got divorced.
Recently, I remarried and am sponsoring my new wife.
In the meantime, my ex-wife has changed her last name.
My question is this: how should I write my ex's name?
1. As it was when I sponsored her and as it appears on our divorce certificate?
2. Or should I write her current name with her new husband's last name?
Thanks!

1. As it was when you sponsored her and as it appears on your divorce certificate

Thanks! That makes sense.
