1. There is an old saying that there are always three motivations for a crime- 'Jar', 'Joru' and 'Zameen' i.e Money, Women and Property. After your lifetime the property willed to you by your mother will devolve through succession equally on your husband and children unless you make a will to the contrary during your lifetime.
2. In the event your mother executes a will in your favour then you will become the absolute owner of the property. Neither your husband nor any of your children will have any claim to the property during your lifetime.
3. Whether or not any harm will be done to you by your husband or children is a hypothetical query.
4. You will be free to execute the will in favour of anyone including a trust or stranger.
