From what I can tell these rules are only for situations where theres no will?
But I agree that this default is not good - it automatically assumes that women are more vulnerable and need paternal assistance.
Obviously some people are in bad positions and need help but why is the government getting involved in this issue in particular? And why now? As opposed to making sure women are educated about finance and legal matters to help avoid problems in the first place?
The point about cukooing made by a PP is a very good one.
