Hi, thanks for your question. It is correct that this would be considered the matrimonial home, however as it is jointly owned by her mother you would not be able to register your home rights on the property given that it is jointly owned with a third party. As part of the financial settlement, your wife's share would be taken into consideration in the settlement and you would be entitled to make a claim for part of this given that it is the matrimonial home and you have made some financial contributions. Non-financial contributions, if any, would also be taken into consideration. Please let me know if you have any further questions about this.
