Wife is not ready for gift deed or relinquishment deed in my favor. She has deserted me since April 2016. In coming days my may file case for maintenance after that i may file divorce case. But till date there is no development.
After my death, despite of my written will, how my son and daughter will get ownership/possession of property because my wife will not sign any documents.
Without your wife's consent or willingness to transfer her share in the property to your name, you cannot become an absolute owner of the entire property.
As said earlier, you can bequeath only your share in the property in your children favor.
Legally you cannot do anything beyond this.
