Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first.
Is this the Matrimonial Home?
Are there any children involved?
What other assets are there?
What income do you each have>
Is your wife remaining in the property with the child?
My apologies I should have asked earlier - how much is the house worth and how much is outstanding on the mortgage?
How much are the savings you each have?
Your wife is wrong.
You have Matrimonial Home rights regarding the property - and a financial claim on the equity.
In fairness the relatively short length of your relationship and the fact that she already owned the property means that you would not get 50% of the equity - but you certainly have a right to some of it - most probably somewhere between 20% and 30%.
You should try and negotiate this with her using Family Mediation
Please ask if you need further details
