If your husbands take home pay is currently over £6k, you have not worked for several years in order to support the advancement of his career therefore earn nothing at the moment. His salary is very probably going to be in excess of £250k per year from next year onwards.
I understand how marital assists may be divided as in what we currently have and I think he would accept that I have a greater share than him in the first instance. (I paid the deposit of our house from my inheritance)
He has a good pension, I have nothing. Even if I was to try to go back to work now I wouldn't be earning anywhere near what I was and I would still be the primary care giver and therefore in reality continue to support the advancement of his career by being available for the children.
What is to be expected to be paid on a monthly basis?
I wouldn't be able to keep my house (unless he was paying the mortgage which is unlikely as it's very high) is there a standard % of his salary or a calculation per child? Presumably he would need to pay for his kids to have somewhere to live and food to eat etc?
