I've noticed people's exes seem to come down with mental health conditions after separation.... You're not a psychologist (are you?) So do don't diagnose.
He doesn't want to see the kid? you can't make him. He can threaten to move out of the primary residence and he can say that you need to manage the animals etc. He can say what he wants and he can tell you what to do... But you don't have to do it.
Best thing to do?
Plan A - Sit down agree and move on. Sell stuff and split proceeds. Now without all the details it is impossible to give accuarate advice. BUT with what you've provided about 60/40 is a ball park. BUT without numbers like amounts in superannuation / shares / how much more equity he had it is hard to be more accuarate. 60/40 is based on you being primary carer and that impacting on your earning capacity.... So agreeing to 50/50 might be a good idea because (again without knowing the size of the asset pool) you could spend 10s of thousands of $$$ on legal advice and walk away with about the same or less because of legal fees and all the stress that comes with it.
Plan B - my mate did this and him and his ex are still friends. Walk into a solicitors office together - put all the information on the table and ask solicitor how this would play out in court and see if you can come to an agreement without a huge legal battle.
Plan C have a huge legal battle.
BUT NOPE it is not reasonable for you to expect dad to pay child care. I think you'll find once you tell centrelink that you're a single parent with 100% care you'll get family tax benefit, more child care benefit and you'll also be getting child support.
Story time - just to get you thinking... I'm a narciissit too - Just ask my ex. She'll tell ya. She had a similar thought process on child care, swimming lessons, clothes, medical bills etc etc.... All of those expenses should be split 50/50. After all that is fair right? and how dare I refuse to pay after all they're my children right? Only fair to pay half of the expenses... With me so far?
But she refused 50/50 care. She refused care above alternate weekends and some holiday time, she refused for there to be any binding agreement about when I see the kids because she didn't want to feel locked in. AND the fact that I just wanted to know when I was seeing the kids meant that I was trying to 'control her' and 'proves' that I'm a 'narcissist'. What if there was something she wanted to do with the kids one weekend but the kids were scheduled to be with me. So we needed to be 'flexible'. "Flexible" really meant she controlled my access.
Now - in your case dad doesn't wanna see the kid (poor form in my opinion - but this is a law forum, so let's stay on task). The fact that you're gonna be primary carer of a young child is reason for you to get a bigger piece of the asset pie. You'll also be getting child support from dad. You have no reason what so ever to expect him to pay anything beyond the child support as assessed by the child support agency. You have no reason what so ever to expect him to pay anything beyond the child support as assessed by the child support agency. Yup wrote it twice, just to make sure....
IF you wanna write down some ball park figures on assets / income / super / laibilities - then you'll get more precise advice on size of asset split.
