I can only tell you the situation in the UK, it may be different in Mauritius.
However if you both live in the UK, it would be UK law and the UK law would be applied to the Mauritius property.
If you want to sell the property, you can apply to court for an order for sale under section 14 of the trusts of land Appointment of Trustees Act.
BUT the court will not usually countenance an order between couples who remain married and you are not getting divorced . The court will not get involved in marital disputes over finances or property of the marriage is going to continue.
Can I clarify anything else for you?
I am happy to answer any specific points arising from this.
