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 long have you lived together
How much is the property worth and how much is outstanding on the mortgage?
What capital investment did you make
What income do you each have?
How much did you sell your flat for and what happened to the money?
How much does a one bedroom property in the same general area cost to buy?
Are there and shared home ownership schemes in your area?
How much would you need to purchase one of those?
Are there any other assets?
Given the length pf your marriage the starting point for division of the equity in the property is 50/50 despite the fact that the house is held in his sole name.
However the fact that he brought all the capital to the marriage could be a reason for him getting a 60/40 share since that would still leave you with enough to purchase a sHared home ownership property.
You also have a potential claim for Spouse Maintenance - which could allow you to claw back some of the extra percentage he might get.
I hope that this is of assistance - please ask if you need further details
Yes it is
