when the women wants divorce from the husband it is known as khula , she can ask the husband to divorce her or go through sharia council here in the UK
also i didnt understand ur point :)
Ignorance is not the blessing in this case. You are a classic example of how we as a society has ignore the fact that in addition to Khula, Islam also has a provision that guy can give right to divorce to gal when nikkahfying. In that case gal don’t have to "ask for khula" but she can divorce guy.
In our male dominant society, maulana sahab skips this section on nikkah nama or sometime just enter "N/A" without asking if guy want to assign the right to gal or not
