Your question is not clearly worded. I am assuming that you are referring to two separate properties: one in the name of your mother in which you are/were residing along with your wife and mother, and another that is registered in your name and to which this question pertains.
I am also assuming that by senior citizen’s case you mean an action under the Maintenance and Welfare of Parents and Senior Citizen’s Act with respect to the second property that is in your name.
If that is so, you have been advised correctly that her case for injunction simpliciter has no merit without possession. You can file an Order 7 Rule 11 application in the said suit for plaint rejection arguing that it lacks a valid cause of action inasmuch as she is neither in possession nor has claimed as much and can’t seek injunction (simple injunction can only be granted where the plaintiff seeks to protect his peaceful possession).
What shape the Order 7 Rule 11 needs to take will depend on the exact facts of the case and your mother’s plaint? Since neither are before me I cannot give you proper advice on this score.
If you have better title—as it appears from your question—you can say so in your written statement along with supporting documents and she will have to amend her plaint to ask for a declaration of title. (Please see Anathula Sudhakar vs P. Buchi Reddy (Dead) By Lrs
& Ors AIR 2008 SC 2033.)
You can also bring a suit of your own for declaration of title and prohibitory injunction. Again, I will need a better grasp of facts in order for me to advise as to what course of action to choose.
You have been advised correctly by your lawyers, it would appear. Your case appears to be strong based on your description. People can send all kinds of legal notices and file all kinds of suits. I know it’s frustrating, but it is what it is.
As for the whole gift deed business, you are free to do as you please if there is no cloud over your title to the property. But it isn’t necessary. You should focus on defending any lawsuit, or, alternatively, on bringing one of your own as advised above.
I hope you have some clarity now. Follow-up questions welcome.
