Once you have a list of ALL assets, absolutely all, you might want to have a friend who is good and maths and lateral thinking help you with the figures and has a bit of knowledge about how you can split things up. That way with a bit of outside help, you can take a bit of emotion out of it. I had a friend who started me off along this path, by simply drawing up a balance sheet of income and outgoing for me and other party for the maintenance side and also the inventory of assets for division. It's important to know likely costs and income of both parties, as this will have an impact of the 50/50 starting point for division of assets.
For myself, keeping the family home was my main aim. I could not see any greater importance than to save a family home (the other party wanted a 55% division in his favour to buy himself a bigger house). I could only achieve keeping the family home by letting go of life insurance policies, a car (which had already been removed from family use for 2 years without permission), children's savings. I was left with the house and an amount in cash to the other party and the other party with the rest basically. Spent months drawing up possible scenarios for division in order to save the home.
The hardest part in division of assets (apart from the other party demanding 55/45 in his favour and refusing the 40/60 offered which led to that person taking me to a 2 year long court action to try get more, failing and resulting in 37/63 division in my and children's favour, more than offered!), was the emotional letting go of some of the children's savings. It was heart breaking for me, a substantial proportion of which was saved from my own childhood by my father and that hurt more than anything else. It really really hurt. I'd proposed to avoid it. The judge made be feel better by saying to the other party as he had chosen his path of leaving us all, he was responsible for the pain the children were suffering, including the pain of of losing the children's money, saying that a family is stronger when all members share the suffering, ie in the end the children will learn from their adversity and it would be up to them to see this as a positive or a negative. I had a very very wise judge and I'll try to pass on the judge's wisdom to the children as they grow up, to see what their father did to them to take their savings is a source of strength and that it's in the end only money and I've vowed to save the lost savings for them, once I can pay off the debts left!
I hope you'll come to a point where you can remove emotion from the assets and you'll see it as a strength that you've shared them and what is lost can be replaced as its material.
