We have reviewed thousands of DIY Wills over the years. The same seven mistakes appear again and again — and any one of them can invalidate the entire document. Here is the field guide to writing your own Will without falling into them.
There is nothing wrong with writing your own Will. Indian law explicitly permits it. A Will written on a piece of plain paper, signed and witnessed properly, is just as legally binding as one drafted by the most expensive senior advocate in Mumbai. The problem is not that DIY Wills are inherently inferior — the problem is that DIY Wills make the same mistakes with predictable regularity, and those mistakes can render the entire document invalid or, worse, valid-but-disputable.
At Law Tarazoo, our advocates routinely review existing Wills brought in by clients for "second opinion" or update purposes. Over the years we have built a working catalogue of the seven errors that account for roughly 90% of contested probate proceedings. Knowing these errors in advance is the cheapest insurance policy you can buy for your estate plan.
This is the single most common reason DIY Wills fail. Under Section 63 of the Indian Succession Act, 1925, a Will must be attested by at least two witnesses. The exact requirements:
Common failures we see:
How to do it right: Bring two competent witnesses to a single sitting. The testator signs the last page in full and initials every other page. Then witness 1 watches the testator sign, watches witness 2 sign, and signs themselves. Witness 2 does the same. All three present in the same room throughout. Date written clearly on the last page. Done.
Under Section 67 of the Indian Succession Act, if a witness to a Will is also a beneficiary (or their spouse is), the bequest to that beneficiary becomes void. The Will itself is still valid, but the bequest to the witness-beneficiary fails.
This is a brutal trap. A husband signs his Will, leaves everything to his wife, and asks his son (a beneficiary in the residuary clause) to witness it. The bequests to the son fail. He inherits nothing under the Will, even though that was clearly his father's intent.
How to do it right: Choose witnesses who are not beneficiaries under the Will and whose spouses are not beneficiaries either. A neighbour, a colleague, a long-term family friend not named in the Will, a notary. Anyone whose only role in the document is to attest the signature.
DIY Wills are riddled with phrases that sound clear in conversation but are legally ambiguous on paper. Examples we see regularly:
Ambiguity is the most common ground for post-death litigation. Family members read the same sentence and reach genuinely different conclusions, each in good faith, and the courts must adjudicate.
How to do it right: Be specific. "I leave my flat at 14, 3rd Asha Nagar, Borivli East, Mumbai 400066, having registration number AAA/123/2018, to my daughter Anjali Mehta, daughter of [father's name], presently aged 25 years and residing at..." It feels excessive. It is not. Specificity is what makes a bequest legally executable rather than legally contested.
A residuary clause is the catch-all sentence at the end of a Will: "All assets and properties not specifically bequeathed above shall go to [name]." It serves three critical functions:
A Will without a residuary clause leaves any "missed" asset to pass under intestate succession — which may go to entirely different people than the testator intended.
Example: a man leaves his flat to his wife, his demat to his son, his FD to his daughter, and forgets to mention the ₹40 lakh he had recently received from selling some land. Without a residuary clause, that ₹40 lakh is divided among all Class I heirs equally under the Hindu Succession Act — including his mother, who he did not intend to inherit anything (assume she has her own substantial assets and he had already provided for her care).
How to do it right: Always include a residuary clause. "I bequeath the rest, residue, and remainder of my estate, whatsoever and wheresoever situate, to [primary beneficiary], and in case [primary beneficiary] predeceases me, to [secondary beneficiary]."
An executor is the person who actually carries out your Will after your death. Without an executor named, the family must apply for "letters of administration" instead of probate, which is a more complex and time-consuming court process. The court appoints an administrator — who may not be the person you would have chosen.
Naming only one executor is risky because:
How to do it right: Name a primary executor and at least one alternate. Ideally, also name a second alternate. "I appoint my wife Priya Sharma as the executor of this Will. If she is unable or unwilling, I appoint my brother Rohan Sharma. If he is also unable or unwilling, I appoint my friend Adv. Vinod Mehta."
If you have ever written any kind of Will before — even a half-finished draft, even something written in a personal diary — a court could potentially treat that earlier document as your "last Will". When a new Will is drafted, it should explicitly state: "I hereby revoke all prior Wills and codicils made by me."
Without that revocation language, a contested probate can become a battle over which document was actually intended as the operative Will. Even when the timing is clear (the new one is dated later), a poorly-drafted later Will can have its terms challenged with reference to the earlier one.
This also matters when you update your Will to reflect new circumstances. Each new Will should revoke all prior Wills. Otherwise the older Will may continue to apply to clauses not addressed in the new one — creating contradictions.
How to do it right: Open every Will with the revocation clause: "I, [name], being of sound mind and not acting under any duress, do hereby make this my Last Will and Testament, revoking all prior Wills and codicils made by me at any time heretofore."
This is the most consequential category of DIY error and the hardest to catch without legal expertise. It manifests in many forms:
How to do it right: Run through every realistic contingency. What if the primary beneficiary predeceases you? What if you and your spouse die together? What if an asset has been disposed of? What if a beneficiary is a minor at the time of your death? Address each in the Will, even if briefly.
This is the post-execution mistake that nullifies all the careful drafting. The most beautifully crafted Will is useless if no one finds it. Tell your executor and at least one other trusted person (spouse, eldest child, advocate) exactly where the original is stored. We have seen Wills sit undiscovered in bank lockers for years, only surfacing when the locker was eventually opened — by which time intestate succession had long since been initiated.
Each of these mistakes is individually small in terms of effort to avoid. None of them require expensive legal advice — they require knowledge and care. But the cumulative effect of getting all seven right (plus the bonus) is the difference between a Will that does what you intended and one that becomes the subject of years of contested proceedings.
If you are committed to DIY Will-drafting, use this article as your checklist. Read your draft against each of the seven points before you execute. If you are uncertain on any of them, consider at minimum a one-hour consultation with a senior advocate to review the draft. The cost is bounded; the protection is unbounded.
The argument we make to clients is not that they cannot draft a Will themselves — they can, and the law explicitly permits it. The argument we make is that the cost of professional drafting is asymmetrically small compared to the cost of any one of these seven mistakes if they occur. A ₹15,000 professionally drafted Will avoids tens of lakhs in post-death legal fees if disputes arise. The probabilities multiplied by the costs make professional drafting overwhelmingly worth it for any estate worth more than about ₹50 lakh.
For smaller estates, careful DIY using this checklist is reasonable. For larger estates, or any with complications — multiple beneficiaries, business interests, minor children, second marriages, NRI considerations — professional drafting is the better economic decision.
