Fortunately, we're not married and 3x was probably a bit generous, it's more like just over 2x. Luckily, she's agreed to what I thought was a fair amount to get it sorted quickly so just need to contact a solicitor and get the ball rolling.That’s the thing, the simple points in my post can very much can change the amounts.
For example, if you are married, the devolve settlement usually aims to achieve a balanced outcome, it’s rarely 50/50. Given she earns 3X wit you do, she has far more mortgage raising ability then you do and would be expected to take the hit on the current house. Likewise their pension growth while you are married and it’s future growth will also be factors in.
This is why we day, ‘get proper advice from a competent solicitor’. You don’t need to engage them for the entire thing and to negotiate on your behalf (avoid this as it will cost you a fortune) but you can pay for an assessment of what a reasonable settlement would look like based on your and your partners financial circumstances and what a court would sign off as reasonable.
If you are married it’s hardly ever as simple as 50/50.
