Yes, the approach proposed by your lawyer is legally sound and, in fact, strategically correct given the present stage of the proceedings.
Since the matter is still at the issue-framing stage and trial has not commenced, the court is concerned with identifying the correct parties, properties, and issues in dispute. Bringing all subsequent and clarificatory facts on record now is procedurally proper and avoids complications later.
Filing two separate Additional Written Statements serves a clear legal purpose and avoids unnecessary overlap. Your AWS, as Defendant No. 1, limiting itself strictly to the fact that you have lawfully divested yourself of your undivided one-third share by executing registered gift deeds, is appropriate. By doing so, you are clearly stating that you no longer claim any right, title, or interest in the suit properties. This helps the court understand that, for the purpose of final adjudication, your transferee now represents your interest. It also prevents future ambiguity about whether you are still contesting partition or shares.
The separate AWS by your younger son, as Defendant No. 2, addressing (a) the incorrect inclusion of a fourth property and (b) the existence of undisclosed movable assets, is also a correct course. These are substantive factual corrections that directly affect the scope of the partition. Since he is the person now claiming through you by virtue of the gift deeds, and also independently affected by incorrect inclusion and exclusion of assets, it is procedurally cleaner for him to raise these points in his own pleadings.
Courts generally prefer this segregation of pleadings because it avoids confusion and makes it clear which defendant is asserting which factual and legal position.
As regards the possibility of challenge by your elder son to the gift deeds, such a challenge is always theoretically possible in litigation, but the strength of such a challenge is extremely weak on law and facts in your case. You were the absolute owner of your one-third undivided share by operation of succession law. There was no injunction or restraint order at the time of execution. The gift deeds were voluntary, registered, and executed in compliance with statutory requirements. A plaintiff cannot invalidate a lawful transfer merely because it reduces the practical benefit he hoped to obtain from delay or future contingencies.
The elder son cannot challenge the gift deeds simply on the ground that they were executed after the filing of the partition suit. Pendency of a partition suit does not freeze ownership rights unless the court specifically restrains alienation. Nor can he succeed by alleging that the gifts were made to defeat his rights, because his right is only to his own one-third share, which remains untouched. Your transfer does not prejudice or diminish his legal entitlement.
If he does attempt to challenge the gifts, the burden will lie entirely on him to plead and prove fraud, coercion, lack of capacity, or violation of a court order. Mere suspicion, displeasure, or allegation of motive will not suffice. Courts are slow to interfere with gifts executed by a competent adult owner, especially a mother disposing of her own share in favour of a caregiving child.
At most, the plaintiff may raise objections such as “suppression of facts” or “belated disclosure.” These objections do not invalidate the gift deeds. Since you are now placing everything on record before issues are framed, and before evidence begins, courts generally treat this as timely disclosure. The absence of any interim injunction works strongly in your favour.
From a structuring perspective, your AWS should be concise and factual: mention the dates of the gift deeds, their registration details, and the clear assertion that you no longer claim any interest. Avoid unnecessary justification or emotional explanation. Let the documents speak for themselves.
Your younger son’s AWS should clearly plead that the fourth property does not form part of the joint family pool due to a prior decree, annex the certified copy of that decree, and seek exclusion of that property from partition. It should also specifically list the movable assets omitted by the plaintiff and pray that they be brought into the common hotchpotch for proper partition. This actually strengthens the fairness and completeness of the proceedings and reflects bona fides.
In summary, the dual-AWS strategy is legally robust, procedurally clean, and well-timed. The risk of a successful future challenge to your gift deeds is minimal, provided your pleadings are clear, factual, and supported by documents. You are doing exactly what the court expects parties to do at the issue-framing stage: place all relevant facts before it so that the real controversies can be accurately framed and adjudicated.
