My mother passed away in 2012. My father remarried in 2016 to a woman who already had three children from a previous marriage. These children are now over 18 years old. Do they have any claim to the property inherited from my grandfather and great-grandfather? What steps can I take to prevent future complications, as my father didn’t inform me about the marriage?

In India, stepchildren generally do not inherit property from their stepparent’s deceased parents. Your father’s remarriage and the presence of his new wife’s children does not automatically give them a claim to the inherited property. To prevent complications, you can consult a lawyer to understand your specific inheritance rights and potentially seek a declaration of heirship.
