Welcome to Just Answer
I am a Solicitor and will assist you.
I am sorry to hear about the break up of the relationship between yourself and your wife.
As you are joint owners of the property - then you both have a right to enjoy occupation of the house.
Whilst you can technically change the locks to the property - if you took such action then you would have to provide a set of keys to your wife on her request. If you did not do so - then she could once again change the locks to gain entry and then provide you with a set of the new keys.
Its best to consider what is going to happen in respect of the matrimonial finances including the matrimonial home. You should consider mediation. A separation agreement could be prepared or if divorce is contemplated an agreement reached in respect of the matrimonial finances being submitted to the family court, which once approved by a Judge will be legally binding.
Let me know if I can help you further.
