It is a shame that children do this to their parents and leave them homeless in the evening of their life. Be that as it may, this property was registered in your wife's favour. So after her intestate demise it devolved on all her legal heirs i,e you and your children. Being a co-owner of the property you have the right to reside in the property. This right cannot be taken away by other co-owners. You should file a lawsuit for injunction against your daughter and her husband to restrain them from preventing you to reside in the property. You are also free to file a suit for partition to cull out your share in the property. The case is to be filed where the property is situated.
