We have exchanged form e

Oh and I just had initial consultation and similar total assets, we both earn about the same and children will be with me approx 60/65 %. Was told 50:50

It’s Based on needs
If you earn about the same you don’t need more ( other than child maintenance)
50:50 could be a likely outcome
But you need legal advice

OP I've recently concluded my own divorce with very similar asset valuations so just wanted to share what the outcome was.

The settlement took 3.5 years and two court appearances and we eventually agreed on 50/50, I've bought him out of his share of the family home, he's given me a pension share and he's kept two rental properties.

I have the DC 95% of the time, we don't have a regular contact schedule. This had absolutely no bearing on the settlement, he is just required to pay maintenance at the CMS rate.

It cost me a lot of money to get to 50/50, if you can agree this at the start I would seriously consider accepting it, especially where current and future earnings are similar.

Good luck

Provided that you have no liabilities, that should be the starting point.
But not all assets are equal. Depends on accessibility.
If there are some liabilities, they need to come off.
What are your respective earnings potential like? That will affect your needs and therefore your settlement.
Childcare and finances were all together for me.
Good luck
