Hi, thank you for your question. Unfortunately the news is not great in your case. The financial settlement the court previously reached was in relation to your children and the children of the marriage and such orders such as orders for sale cannot be varied - even if you were to attempt to vary it the court will not consider your granddaughter as a relevant child arising out of the marriage. Your husband will not be liable to pay anything towards the house outgoings unless it is included in the court order.
However, upon sale of the home you will be homeless and you will be entitled to attend your local authority housing office to submit a homelessness application and they will assess whether they have a duty to assist you - it will be likely that they will have a duty if you have a minor child in your care.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you.
