Wife demanding her share in property.

If you are living in Goa, The Portuguese Civil Code lays down  a moeity right to your wife & children. And accordingly from the date of your marriage your wife has acquired equal right in your property. Therefore in that  event you are not the owner of entire property though it stands in  your name.

If you are living else where and governed by the provisions of Hindu law than in that case, except the maintenance of your wife and childern according to the standards they are entitled you can provide them by way of maintenance & cost of residence. But your wife cannot claim any right in your property as a co-sharer.

As per my knowledge,

If that property is self acquired, i.e. you have bought it yourself. Then nobody, other than you has any right on this.

However if that property is ancestral, then child born out of your wedlock will have right.

thats the way to go !!!
