Mutual Wills explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Mutual wills confer reciprocal benefits and become irrevocable after one maker's death where the survivor took a benefit and there was an agreement not to revoke. A joint will in one document operates as two wills, and a contingent will takes effect only if the event happens.
Mutual or reciprocal wills
Two persons are said to make mutual wills when they confer reciprocal benefits upon each other under their wills. In other words, a mutual will is one of two wills made by two persons, giving each other similar rights in each other's property — as where one bequeaths all her property to the other, and the other makes a will giving all her property to the first.
The peculiarity of mutual wills is that they become irrevocable after the death of one of them if two conditions are satisfied:
- (i) the survivor has received benefits from the deceased under the mutual wills; and
- (ii) there was an agreement between the two testators that they shall not revoke their respective wills.
The handbook states elsewhere, as a general principle, that the testator's right to revoke during his lifetime is absolute and can neither be waived nor restricted. It then identifies the single exception: "the only instance in which a will cannot be revoked is in the case of mutual or joint wills which become irrevocable after the death of one of the makers."
That makes mutual wills a genuine planning tool — for a couple who want to be sure that the survivor cannot redirect the estate away from the children of a first marriage, for instance. But the irrevocability depends on both conditions, and the second one, the agreement not to revoke, is exactly the element that is usually left unrecorded.
The drafting response is to state the agreement on the face of both wills, in terms, so that it can be proved after one maker has died. Two wills that happen to mirror each other are not mutual wills; they are two ordinary wills, each freely revocable.
There is a second peculiarity. Normally a will is revoked by the marriage of its maker — but in the case of mutual wills, the marriage of one of them does not revoke the will of the other.
Joint wills
In Halsbury's Laws of England, a joint will is defined as a will made by two or more testators, contained in a single document, duly executed by each testator, and disposing of either their separate properties or their joint property. The commonest example is one made by a husband and wife, disposing of their property under one joint will.
In law, a will made by two persons is not considered to be a single will. In effect it constitutes two wills. On the death of each testator it operates as the will of that testator, disposing of his separate property. So on the death of one testator, such a will can be admitted to probate as the will of that testator, and on the death of the survivor it will be admitted to probate as the disposition of the property of the survivor.
However, a joint will relating to joint property can be proved only on the death of the survivor. And where two persons make a joint will and one of them dies, the survivor can revoke his will — unless he has taken some benefit under the will of the deceased co-testator.
| Mutual wills | Joint will | |
|---|---|---|
| Documents | Two separate wills | One document, executed by each testator |
| Effect in law | Two wills, reciprocal in content | Not a single will — constitutes two wills |
| Probate | Each proved on its maker's death | Separate property: on each death. Joint property: only on the survivor's death |
| Revocation by survivor | Barred where benefits received and an agreement not to revoke existed | Permitted unless the survivor took a benefit under the deceased's will |
| Marriage of one maker | Does not revoke the other's will | General rule applies |
The comparison above points to a clear drafting preference for a married couple, and it turns on probate rather than on substance.
A joint will covering joint property can be proved only on the death of the survivor. If the couple holds the family home jointly — the usual case — the estate of the first to die cannot be administered as to that property until the second dies, which may be decades. Two separate mutual wills avoid the problem entirely: each is proved on its own maker's death.
Where the couple also want the survivor bound, the mutual wills route gives that as well, provided the agreement not to revoke is recorded. The joint document offers no advantage that two mirror documents do not offer more cleanly.
Contingent or conditional wills
A will may be made contingent upon the happening of an event, so that if the event does not happen, the will has no effect. The handbook's illustration is a will containing the clause "Should anything happen to me during my passage to Jammu and Kashmir or during my stay", which was held to be a conditional will.
Such a will takes effect only if the contingency happens. If the contingency does not happen, the will is not entitled to probate. Similarly, a will may be made conditional on the assent of a third person, and would be entitled to probate only if such assent has been given.
Conditional wills are almost always made accidentally. A client about to travel writes a will opening with words like "in case anything happens to me on this journey", intending it as a general will made on the occasion of a trip.
If the journey is completed safely, that will is dead — the contingency never happened, and it is not entitled to probate. The client who never revisits it dies intestate, believing he has a will.
The drafting rule is simple: never let the occasion of making the will appear as a condition of it. If the client genuinely wants a will limited to a journey, say so deliberately and diary a replacement on return. Otherwise, keep the reason for making the will out of the operative words altogether.
Duplicate wills
A duplicate will is one of which two or more copies are made. If such a copy is signed by the testator, it can operate as the original will.
The consequence to watch is the revocation rule. Where a will is executed in duplicate, one of which the testator retains while the other is deposited in the custody of another, the destruction by the testator of the will which was in his own possession revokes the will — both copies, not merely the one destroyed.
Three further categories the handbook names
- Statutory will. A simple will, often called a statutory will, typically appropriate for those with simple, small assets. Being generic and common, they are quite simple to put together in a short time.
- Deathbed will. Also known as an oral will, generally spoken by the deceased moments before death, sometimes in front of a large group to ensure it is carried out. The handbook notes that certain states do not acknowledge deathbed or oral wills and that they are regularly disputed, leading to protracted litigation. In India they have no footing outside the privileged will categories.
- Pour-over will. An alternative where the testator has a living trust holding a significant portion of the assets. Its purpose is to transfer property to the testator's trustee: any wealth remaining in the testator's own possession at death is transferred into the living trust, from which it can be dispersed to beneficiaries.
Practical checklist
- For a couple, prefer two mirror wills over one joint document.
- Where irrevocability is wanted, record the agreement not to revoke in both wills.
- Remember mutual wills bind only where the survivor took a benefit as well.
- Warn that a joint will over joint property is proved only on the survivor's death.
- Keep the occasion of making a will out of its operative words.
- Where a genuine contingency is intended, diary a replacement when it passes.
- Track every duplicate — destroying the testator's own copy revokes the will.
- Treat a deathbed declaration as unenforceable outside the privileged categories.
Common mistakes
- Calling two mirror wills "mutual wills" when no agreement not to revoke was recorded.
- Using a single joint document for a jointly owned family home.
- Opening a will with "in case anything happens on this trip".
- Assuming the survivor of a joint will is always bound.
- Destroying a spare copy without realising the effect on a duplicate will.
- Relying on a pour-over structure without the living trust actually in place.
