Merton I know only what has just happened in my family. The couple were very reasonable with each other regarding the money side of things, but as soon as they told their respective solicitors what they had agreed they were told the judge wouldn't accept it as it was too lopsided. One had to give the other quite a lot more even though they were having joint custody of the child. The difference here is that they have already settled the property arrangements. One is keeping the marital home (no mortgage) and the other has enough money to buy a new home and has done so. With you so much could change before the time comes to divide the proceeds of the property. One or other of you could lose your job and not be able to keep up your payments etc etc. I would expect your wife to paying towards the upkeep of the children, if they are hers, by way of maintenance. Just try and be fair to each other, do as you would be done to. Really, you need Barmaid to answer your question. I hope you can work it out amicably for the sake of the children at the very least.
