Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How old are the children
Who has the day to day care of the children?
I am afraid I have to ask - when were you last drinking?
Who helps you care for the children?
Is your husband active in their care?
How much is the house worth and how much is outstanding on the mortgage?
what other assets are there and what income does your husband have?
How much is th ehouse actually worth and what is your best guess on the outstanding mortgage?
At present the risks you face are not the financial ones but the simple fact that your history of drinking means that your husband will almost certainly be successful in any applictaion for the children to spend more time in his care than in yours.
I am sorry to be brutal but it is important that you know this.
If you wish to keep the children in your primary care then you need to have been completely dr for at least 6 months.
At that point you would have an excellent chance of arguing that the chidlren spend at least as much time with you as with their father - if not more
At that point the housing needs of you and the children will have priority so far as the family court is concerned with you either remaining in the current property - or it being sold and you having sufficient funds to purchase an alternative one
You will also be entitled to Child maintenance - 19% of his gross income at most
Please ask if you need further details
