My apologies for the delay
I am also sorry as I have bad news for you
The fact that the house is in your sole name does not mean that your husband has no claim on it - and the starting point is 50/50.
Having said that he wont get 50% - partly because you purchased the property and partly because you have the care of your child.
he is under a duty to help you house your child, which means that it is unlikley that he will be able to force a sale of the property befor eyoru daughter is 18.
In order to resolve the finances following a divorce the first step has to be full disclosure of all assets - if an application is made to the ocurt then that disclosure is made by way of a Form E
As you can see full disclosure does indeed involve income as well as assets and pensions - and the exchange of information has to be mutual
I hope that this is of assistance - please ask if you need further details
