I am the only child of my parents. I am married with 2 kids. My parents stay with me. I lost my father two years back. He & my mother has a house in Kerala. After my father's death my mother legally gave the house in my name. We all stay together in West Bengal. In the deed, which was in Malayalam , it was written that my mother has given me the house for which I have paid her 10L.

Actually, I do not know to read Malayalam, so had not gone through the details of the deed. One of my cousin in Kerala co-ordinated the whole thing so we were rest assured. In fact, there has been no money transactions that has taken place in this deal, it was just put in writing , so that the deal is clear and complete . That is what we were told. Now, I am facing a problem.

I am a govt. employee. As submitted these papers at my office, as per rules, to declare my property that I have inherited. I am being questioned as to where I got that 10 L from. It was only then that I came to know that the deed paper said so. We submitted an affidavit ( on legal advice) on behalf of my mother, wherein she declared that no such money was paid and the 10L value was only a quantification for her staying with us over the years. This has also not helped. The office wants to know, why the deed was made like that. Explanation required. How can I clear myself of this. I tried to be honest and so followed the rules and declared my property. There are so many who have so many properties around but has not declared them. I have put myself into trouble by following rules.
