As a matter of fact you do not have a marketable title to your property.POA will not confer title to you. Therefore you better immediately sell the property to your wife in the capacity of POA and get it registered on her name. By doing this, you are securing the property from two dangers, i.e.,by acquiring the title to the property once your wife becomes the owner, it becomes her own and absolute property and she is shielded with married women property act. Nobody can claim any share in it.

1. You are at liberty to file a lawsuit for eviction against your son and daughter-in-law to evict them from your property as without your permission none of them has the right to reside in the property.

2. You can also sell the property if you desire whereupon none of them can claim any share in the sale proceeds.
