My info is old but I think is still be valid. If you have the kids living with you the split of assets would be 70% to you 30% her, but you may have to pay maintenance to her if she cant get work and you earn more than her. If the kids are over 11 - 12yo their wishes will be taken into account. Over 15yo they can state what they want to do. Whatever happened before you divorce/do your property settlement wont be taken into account (ie you supported her, she worked, didnt work etc. doesnt matter). If you get a divorce, you only have a year to do the property settlement then any division of assets must be agreed to by both of you. Re-read that carefully. A year goes by very quickly, especially with a new boyfriend on the scene. Fact: After divorce and no property settlement finalised within the year, if you havent been able to reach agreement re division of assets, ie selling the house and giving her a share, etc. she cant force you to, it must be agreed by both. If she agrees to sell the house and you then cant agree on division of assets it will go into a trust account until you both agree
