I'd be curious to know if you share my view,
I personally think the family laws here are some of the fairest pieces of legislation in the country - I can't remember the last time I read a case and thought that the outcome was unfair.
Obviously there might be some bias since I work as a family lawyer, but in some of my other practice areas I'm frank in calling out any unfairness (including residential tenancy law).
The only thing I can think of that bugs me a little with the laws are the difficulties in implementing and enforcing a binding financial agreement.
