Children with special needs maintenance

I'm in the process of sorting out a financial settlement (going through a divorce). Two of our children have special needs and one needs caring for during the day due to severe anxiety and not being able to go to school. Both have DLA and Education, Health and Care Plans in place documenting the difficulties. For the past 4 years my (separated) husband has refused to take time off work to share the childcare challenge or give me more money so I could take time off. Chances are that even if I get the house in the settlement, I may have to give up work to care for my children and then won't be able to pay the mortgage anyway.
Is there special provision for this, as all the Divorce Calculators online don't take this into account? I'll be losing income and pension and probably be homeless. Currently the only way I can go to work is because my older daughter (now adult) cares for her sibling.

The courts will always see the parent who is th full time care of children gets priority and especially in your case with special needs.

I'm not an expert but in my situation Im working part time as much as I can and courts recognised that and ordered my ex to pay my mortgage and essential bills by way of spousal maintenance.

Ex didn't want to give me anything so we had a final hearing for 4 days and judge made final decision. My advise if you need something for yourself and the children then fight for it and don't give up. Hope it goes well.

Thanks Cheesestring. If you don't mind me asking will your ex have a share of the house when the children are grown up?

I hope I read this right and so going ahead to assume you've been separated for 4 years now… you can fight for this in court and if this is true, I'm sure the judgment will be in your favour.
