The idea is that judges would have guide lines like they do when sentencing, so you murder its mandatory life manslaughter more loose guidelines, so the Canadian idea is that if you were married so many years have x number of kids there would be an upper and lower limit for global asset division.
Practically its impossible though, it would work well if you were married one year with no kids you were both born and live here and are healthy and able to work, you could just say you both keep what you have.
But what if you were married for 20 years husband is 65 wife 40 kids 4-6 and 19 at uni, dad is about to retire mum has just found out she has cancer, oldest lives with dad the other with mum, mum is a doctor earning 100k dad has a pension which will pay £1000 per month, mums pension
CETV 200k before actuary,
FMH equity 150k bugger all else as assets, the eldest kid with dad is blind and needs lots of help, the FMH is adapted for him, mum and the two other kids are in rented, they both say they need the FMH.
What kind of mathematical equation could work that out?.
These ideas come and go, they spend a fortune debating and then nothing changes, the meat of the law has hardly changed since 1973, it gets tweaked, new case law plods by, but it is what it is.
From what little i know of Scots law they would do better to take from that if anything.
