Accordingly, the point is held in favour of the plaintiffs and against the defendants. 19. In Re. Point No. 2 & 3: One of the contentions of the plaintiffs in the plaint is that Ex.A1 was cancelled by executing Ex.B1 relinquishment deed fraudulently. At the same time, defendant Nos. 1 to 4 contended that Ex.A1 will was obtained fraudulently and, in view of the fraud played on Venkataratnamma, she cancelled the will and executed Ex.B1 relinquishment deed receiving Rs.20,000/-. Thereby, the 1st defendant became owner of the property. Execution of Ex.A1 and Ex.B1 are not in dispute. The dispute is only with regard to fraud allegedly played by the 1st defendant in obtaining Ex.B1. 20. When the defendants asserted that Venkataratnamma executed Ex.B1 relinquishing her joint right in the property receiving Rs.20,000/-, the initial onus of proof is on the defendants to substantiate the same by adducing cogent and satisfactory evidence. If the defendants are able to establish execution of Ex.B1, the burden of proof will shift on to the plaintiffs to disprove execution of Ex.B1 and fraud played by the 1st defendant in obtaining Ex.B1. To substantiate the contentions of the defendants, the 1st defendant himself was examined as D.W.1 and testified about the alleged fraud played by the 1st plaintiff in obtaining Ex.A1, informing the same to the 1st defendant by his mother Venkataratnamma after her return and execution of Ex.B1 canceling the will. In cross-examination of D.W.1, nothing was elicited to discredit the testimony of D.W.1 regarding due execution of Ex.B1 in sound disposing state of mind. In cross-examination, D.W.1 admitted that there was no partition between himself and his mother Venkataratnamma and they enjoyed the property jointly. D.W.1 further admitted that no property was given to the 1st plaintiff either during the lifetime of Venkataratnamma or after her death and D.W.1 admitted that Venkataratnamma, his mother, executed registered will bequeathing her half share in favour of mother of P.W.1 but, after one week from the date of execution, the will was cancelled on the ground that it was obtained by playing fraud. Venkataratnamma executed both cancellation deed and relinquishment deed on the same day and he also accompanied to registrar's office at the time of execution of Ex.B1. No suggestion was put to D.W.1 that Ex.B1 was obtained by playing fraud or undue influence etc., except suggesting that Ex.B1 was not executed by Venkataratnamma and got denial of it. 21. The 1st defendant also got examined Devu Chittibabu who had acquaintance with the 1st defendant and his mother. D.W.2 attested the relinquishment deed Ex.B1. At best, his evidence is helpful to prove execution of Ex.B1 by Venkataratnamma by affixing her thumb impression in his presence after the contents were read over to Venkataratnamma. Ex.B1 was executed at the house of D.W.1 and registered the same at the house of D.W.1 and that Ex.B1 was not obtained by using any force or undue influence and that Ex.B1 was executed voluntarily. In cross-examination of D.W.2, nothing was elicited to discredit the testimony of D.W.1 except suggesting that Venkataratnamma never executed Ex.B1 and it is a fabricated and forged document but the same was denied by D.W.2. 22. Similarly, Tummidi Mohanarao was examined as D.W.3 to prove execution of Ex.B1 relinquishment deed by Venkataratnamma. D.W.2 is the second attester of Ex.B1 and his evidence is almost in the lines of D.W.2, the other attester. In addition to that, D.W.3 testified about receipt of Rs.20,000/- by Venkataratnamma. In the entire cross-examination, nothing was elicited to rebut the testimony of D.W.3. On the other hand, a bald suggestion was put to him that Venkataratnamma never executed Ex.B1 and that the same was introduced by the defendants but the suggestion was denied by him. 23. On close analysis of evidence of D.Ws.1 to 3, Venkataratnamma executed Ex.B1 relinquishing her right in the undivided property allotted to her and her son the 1st defendant under Ex.A2 partition deed. Even the basis for execution of Ex.A1 is partition deed Ex.A2. However, Venkataratnamma, testatrix, reserved her right to revoke the will during her lifetime. In exercise of the power of revocation reserved on Venkataratnamma, she executed Ex.B1 relinquishment deed dated 08-12-1975. The contents of Ex.B1 disclosed that she relinquished her undivided share in the property receiving Rs.20,000/-. Even as per Ex.A1 registered will and Ex.B2 certified copy of the will, the testatrix, Venkataratnamma, bequeathed her share in favour of the 1st plaintiff and the will comes into effect only after death of Venkataratnamma but, during the lifetime of Venkataratnamma, she relinquished her right and ceased to be the owner of undivided half share bequeathed to the 1st plaintiff. Execution of Ex.B1 by Venkataratnamma, receiving Rs.20,000/- towards consideration for relinquishing her right in the undivided property, conferred absolute right on the 1st defendant. Thereby, the 1st defendant became absolute owner of the property. Though the plaintiffs contended that Ex.B1 was created for the purpose of denying the claim of the plaintiffs but the same was not substantiated by any evidence. On the other hand, the defendants proved execution of Ex.B1 by Venkataratnamma. When a party disputed validity of any document on the ground of fraud, coercion, undue influence, duress, mistake etc., in obtaining the document, it is incumbent upon such party to disclose particulars in detail as per Order VI Rule 4 of the Code of Civil Procedure. In Afsar Sheikh and another Vs. Soleman Bibi and others, the Apex Court ruled that "Undue influence, fraud, misrepresentation are cognate vices and may, in part, overlap in some cases, they are in law distinct categories, and are in view of Order 6, Rule 4, read with Order 6, Rule 2 of the CPC, required to be separately pleaded, with specificity, particularity and precision." The Apex Court reiterated the same principle in Smt. Sukhdei (dead) by L.Rs. Vs. Bairo (dead) and others. In view of the law declared by Apex Court, details of fraud, undue influence etc., need be pleaded and proved by both the plaintiffs and the 1st defendant in obtaining either Ex.A1 or Ex.B1 but both the parties failed to disclose in detail particulars of fraud, undue influence etc., both in pleadings and evidence. In those circumstances, it is difficult to hold that either Ex.A1 or Ex.B1 was obtained by fraud, undue influence etc., to vitiate the same. Therefore, by virtue of Ex.B1, the 1st defendant became owner of entire property allotted to the 1st defendant and his mother Venkataratnamma under Ex.A2 partition deed. 24. One of the contentions of the plaintiffs is that after the advent of the Act of 1956, the property allotted to the share of Venkataratnamma became her absolute property by virtue of Section 14 (2) of the Act of 1956. However, joint ownership of Venkataratnamma is not in controversy. Therefore, it is wholly unnecessary to decide ownership of Venkataratnamma in the half share of the property allotted to the 1st defendant and Venkataratnamma in the partition under Ex.A2. 25. Learned counsel for the plaintiffs drawn attention of this Court to Mulla Principles of Hindu Law, 28th Edition by S.A.Desai, Volume – I, Page Nos. 122 to 130, contending that share obtained by a widow on partition of joint family property, the same cannot be treated as stridhana property under Mitakshara Law as held in Debi Mangal Prasad Singh Vs. Mahadeo Prasad Singh and others (7th supra). In Smt. Kamala Devi and another Vs. Bachulal Gupta and others (5th supra), the Apex Court is of the view that "It does not therefore pass on her death to her stridhana heirs, but reverts on her to the next heirs of her husband in the absence of an express agreement amongst the co-sharers to the contrary." However, these principles are not in quarrel and not at all relevant for deciding the present controversy. Even the principles relating to features of stridhana in the above text, a Hindu female may acquire property from various sources. She may acquire it by gift, or by inheritance, or on partition. She may also acquire it by her own labour and skill. However, all property acquired by her is not stridhana. Whether a particular kind of property is stridhana or not, depends on: the source from which the property was acquired; her status at the time of acquisition i.e. whether she acquired it during maidenhood, covertures, or widowhood; and lastly; the school to which she belongs. While considering whether property acquired by a widow or a woman is stridhana or not, the Court has to keep in mind the above three principles. Even if these principles are applied to the present facts of the case, schedule property is not stridhana property of Venkataratnamma. However, it is not the case of the plaintiffs that schedule property was stridhana property of Venkataratnamma. It is the specific case of the plaintiffs that it was the property of Venkataratnamma allotted to her share in the partition. Therefore, the principles applicable to stridhana property cannot be applied to the present facts of the case. 26. Refuting the contentions of learned counsel for the plaintiffs, learned counsel for the defendants, in support of the judgment of the trial Court, drawn attention of this Court to K.L.S.V.E.Annamalai Chetty Vs. K.L.S.V.E.Subramanian Chetty and others (1st supra). In the said judgment, the Privy Council, while dealing with a suit for partition, held that "The burden of proving in an action for partition of joint family property that any particular item of property is joint, primarily rests upon the plaintiff. Circumstances no doubt may readily cause the onus to be discharged, but where this has not been done and in the face of direct evidence accepted by the High Court, Privy Council is not at liberty to speculate as to alternative possibilities." The principle laid down in the above judgment may at best helpful to compel the plaintiffs to discharge their initial onus of proof regarding nature of property but, for deciding the present issue regarding woman's estate, it is not relevant. 27. Learned counsel for the defendants further drawn attention of this Court to Bhagwantrao Jairam and another Vs. Punjaram Sadashiv and others, wherein Nagpur High Court had an occasion to deal with woman's estate and held that "The property which a widow acquires under Mitakshara law on a partition among sons cannot be treated as property given to her in lieu of her maintenance but should be treated as property in the same category as one inherited from the husband." 28. In D.S.Lakshmaiah and another Vs. L.Balasubramanyam and another (4th supra), the Apex Court, while discussing about burden of proof, laid down certain principles similar to the principles laid down by Privy Council in the decision referred supra. Learned counsel for the defendants further contended that when a member of joint family carrying on business cannot be presumed to be the business of the joint family. In support of this contention, learned counsel for the defendants drawn attention of this Court to Bhuru Mal Vs. Jagannath and others (2nd supra), wherein the Privy Council held as follows: "Though a business, if it belongs to a Hindu joint family, is an item of joint family property, special
