You can legally exclude your mother from getting any share in your self-acquired property by proper estate planning.
✔️ Best option: Make a WILL
Execute a registered Will clearly stating:
Entire property goes to wife and child only
Expressly exclude your mother
Mention reason briefly (not mandatory, but helpful to avoid disputes)
Get it signed by 2 witnesses
Registration is advisable (though not compulsory)
👉 After your death, property will pass as per Will, not as per succession law—so your mother will not get a share.
✔️ Stronger protection (optional)
You can also:
Nominate wife/son in policies & investments
Convert property into joint ownership with wife (with survivorship clause)
Create a family trust (advanced option)
⚠️ Important points
Without a Will → under Hindu Succession Act, 1956 your mother is Class I heir, so she will get equal share.
A Will can be challenged, so:
Draft carefully
Prefer medical fitness certificate + video recording (good practice)
✔️ Conclusion
👉 Make a clear, well-drafted Will — this is sufficient and most practical.
