Parents executing joint mutual Will should know that in case of death of one parent, the surviving parent can’t change the beneficiaries of the Will unilaterally (AI generated representative image)

Recently there was a case in Kerala High Court where, despite the parents’ Will stating that the daughters would be excluded from inheriting any family property and that everything will go to the sons, the daughters took legal action and ended up winning 11/80th share of the property.
The reason the daughters’ won is because the parents had executed a joint Will and not a joint mutual Will. This meant that when their mother executed a settlement deed in favour of the daughters after their father died, she had legal rights to do so as it was a joint Will.
If it was a joint mutual Will, she could not have done so as the surviving spouse can’t change the beneficiaries or terms of a joint mutual Will after the death of the other spouse.
However, by creating the settlement deed for the daughters, she established a new legal document that was separate from the Will. To revoke a settlement deed, she had to follow the due process of law as it can’t be unilaterally cancelled. But during her lifetime, she unilaterally cancelled this settlement deed on her own.
As a result, the Kerala High Court ruled that once a settlement deed is executed, it cannot be cancelled unilaterally, especially not on the ground that it has not come into effect yet.
So, the daughters won the case in high court and got 11/80th shares in the property.
Even though the brothers argued that their parents had executed a joint mutual Will, they failed to prove this in court. As a result, the high court decided that the Will in question was a joint Will and not a mutual Will. It was held that merely because a will is executed jointly by two persons, it does not automatically become a mutual will.
What are joint and mutual Wills?
Shraddha Nileshwar, Head – Will & Estate Planning at 1 Finance, explained to ET Wealth Online: A joint Will is a single testamentary document executed by two or more persons (typically spouses), recording how each testator’s (person creating the Will) own property is to devolve after their deaths.”
Legally, it is just two (or more) Wills combined in a single document; each testator’s dispositions are still separate and take effect only on their respective demise.
Nileshwar further explained that a mutual Will (or mutual joint Will) when executed in one document) goes a step further: it is based on an agreement between the testators that
- (a) each Will confer a reciprocal benefit on the other, and
- (b) the arrangement will not be revoked unilaterally once one of them dies.
Mutuality normally shows up in two ways: there is a binding agreement not to revoke except by mutual consent during both parties’ lifetimes, and the surviving testator receives a benefit in the form of rights over the deceased’s property under the same Will arrangement.
| Aspect | Joint Will | Mutual Joint Will |
| Document | One document signed by two or more testators. | Often one joint document, but can be separate wills. |
| Core idea | Combined expression of individual wills. | Contractual arrangement + reciprocal benefit. |
| Mutuality / non-revocability | Not presumed; must be expressed, otherwise revocable for its own share. | The surviving testator typically is bound not to defeat the agreed scheme. |
| Basis for court’s inference | Plain wording; no “implied mutuality”. | Agreement + benefit must be evident from language. |
| Kerala HC position (2026) | Mere joint execution and deferred operation till both deaths do not create mutuality. | Mutuality cannot be inferred unless clearly depicted in will. |

What should Indian families know about joint and mutual Will for succession planning?
Nileshwar says that for Indian families, especially those using a mix of wills and lifetime transfers for succession planning, this judgment underlines several practical lessons.
(a) Draft Wills with crystal-clear intent:
- Do not rely on generic, informal language in joint wills and assume that “courts will understand our wish to keep things fixed after the first death.” The Kerala High Court has made it clear that mutuality must be explicit; it will not be presumed merely because the will is joint or takes effect after both deaths.
- If spouses truly want a binding arrangement so that the survivor cannot later rewrite the scheme, they must clearly record (i) the mutual agreement, (ii) the benefit to the survivor, and (iii) that the arrangement becomes irrevocable upon the first death.
(b) Understand the difference between “will planning” and “deed planning”:
- A Will is inherently revocable during the testator’s lifetime; its dispositions only take effect after death, and until then, circumstances can be re-aligned.
- A settlement/gift/partition deed, once validly executed and accepted, is a completed transfer; the transferor cannot unilaterally pull it back later on purely personal or emotional grounds.
(c) Use settlement deeds consciously, not casually:
- Because a settlement deed cannot be revoked unilaterally, families must treat it like a final step in succession planning, not a casual preliminary gesture.
- If parents want flexibility (for instance, to respond to future conduct of children), they may be better served by a carefully drafted Will, possibly with conditional bequests, instead of an outright settlement.
(d) Female heirs and equitable arrangements:
Kerala courts have pointed out in multiple rulings that voluntary partition or settlement deeds can rightfully grant property rights to female heirs even where earlier customary law would not have given them an automatic share.
The present judgment, by upholding the validity of the mother’s right to settle her share in favour of her daughters and protecting that settlement from unilateral cancellation, strengthens the message that courts will respect conscious family arrangements that aim at equitable distribution.
Keshav Singhania, Head – Private Client, Singhania & Co, said to ET Wealth Online: “For Indian families, the judgment is a practical reminder that succession planning cannot be approached casually especially where arrangements like joint Will or joint mutual Wills are involved.”
The key takeaway is that courts will look beyond the document itself and examine the underlying intent and understanding between parties. Where there is evidence of a clear arrangement, particularly in the case of mutual wills, it may have binding consequences.
At the same time, families should note that probate courts are primarily concerned with the validity of the last will. Any dispute around breach of understanding or competing claims is typically dealt with separately, which can lead to prolonged litigation.
From a practical standpoint, the lesson is simple: avoid informal or loosely structured arrangements. Clarity in drafting, careful choice of structure, and, where required, professional advice can go a long way in preventing disputes later.
The practical takeaway for anyone considering this route is straightforward: joint and mutual wills are legally valid instruments in India, but their enforceability is entirely a creature of case law rather than statute.
Does the Indian Succession Act and Hindu Succession Act both specifically recognize joint or mutual Wills?
According to Singhania, neither the Indian Succession Act, 1925, nor any other codified statute expressly addresses joint or mutual wills. The Indian Succession Act defines a will and sets out the framework governing testamentary capacity and execution but is silent on the concept of two or more testators coming together to execute a conjoint or reciprocally binding testamentary arrangement.
According to Singhania, the Hindu Succession Act is focused on intestate succession and doesn’t really engage with Wills. In practice, the concepts of joint and mutual Wills have developed through judicial interpretation rather than statutory recognition. Courts have recognised them, particularly in the context of mutual Wills where there is a clear underlying understanding between the parties.
