>>Can I obtain a decree absolute without her consent?
Possibly but whether you can or not depends upon whether your wife has grounds to prevent you. The simple fact that financial matters have not been resolved is not sufficient but if your wife can show that she would suffer financial prejudice if you obtained decree absolute she could prevent you. Typically this would be because, for example, she would lose out under any pension you may have. However, the possible prejudice can take many forms.
