Many people assume a will lets them decide freely who gets what. Under Islamic law as applied in Pakistan, that is not the case. A will - wasiyyat - is a limited tool. It sits on top of a fixed system of inheritance shares (Faraid) that the testator cannot override. Understanding the one-third rule is the difference between a will that works and one a court sets aside. This guide explains the limit, the heir-consent trap, validity, revocation, and how the rules differ for non-Muslims.
What a will (wasiyyat) actually is
A wasiyyat is a declaration by which a person (the testator) directs how part of their property should be distributed after death. It only takes effect on death, and it operates on the net estate - what remains after funeral expenses and the payment of all debts. Whatever is left after those deductions is the pool from which the one-third bequest is measured.
For Muslims, testamentary freedom is governed by Islamic personal law, preserved in Pakistan through the Muslim Personal Law (Shariat) Application Act 1962 and the Muslim Family Laws Ordinance 1961. For non-Muslims, wills fall under the Succession Act 1925. The two regimes are very different, so the first question is always: which law applies to you.
The one-third rule explained
The core rule is simple to state and easy to get wrong. A Muslim may give away by will no more than one-third of the net estate. The other two-thirds is reserved for the legal heirs and is divided among them according to their fixed Quranic shares. The rule traces to a well-known instruction of the Prophet (peace be upon him), who limited a bequest to one-third and remarked that even one-third is a great deal.
Two separate restrictions flow from this, and both must be satisfied:
| The two limits on a Muslim will | Effect |
|---|---|
| The quantum limit - a bequest cannot exceed one-third of the net estate | Any amount above one-third is invalid unless all heirs consent after death |
| The heir limit - a bequest cannot be made in favour of a legal heir at all | Invalid even if within one-third, unless all other heirs consent after death |
The two limits stack. A gift of 20% of the estate to your son is within the one-third cap but still invalid, because he is an heir - unless your other heirs agree after you die.
Why you cannot favour an heir without consent
Heirs already receive fixed shares under Faraid. Allowing the testator to top up one heir by will would let people quietly reshape the divinely-set distribution - favouring one child over another, or a wife over the parents. Islamic law blocks this. A bequest to an heir is void unless every other heir consents. Under Sunni (Hanafi) law - which most Pakistanis follow - that consent must be given after the testator's death, when the heirs know exactly what they are giving up. Under Shia law, consent may validly be given during the testator's lifetime.
Who counts as an "heir" is fixed at the moment of death, not when the will is written. If a person named in your will turns out not to inherit (for example, because a nearer heir excludes them), the bequest to them may be treated as a gift to a non-heir and can stand within the one-third limit.
A worked example
Take an estate worth PKR 30 million after debts and funeral costs. The testator leaves a widow, one son and one daughter, and wants to bequeath money to a charity and to a grandchild who is not an heir (the son and daughter exclude the grandchild).
| Step | Amount (PKR) | Rule applied |
|---|---|---|
| Net estate | 30,000,000 | After debts and funeral |
| Maximum bequeathable by will | 10,000,000 | One-third cap |
| Bequest to charity + non-heir grandchild | Up to 10,000,000 | Valid without heir consent |
| Remaining estate for Faraid | 20,000,000 | Two-thirds, divided among heirs |
| Widow's share (1/8 of the 20M) | 2,500,000 | Fixed Quranic share |
| Son and daughter (residue, 2:1) | 11,666,667 / 5,833,333 | Son takes double the daughter |
Had the testator instead tried to leave PKR 10 million to the son, the bequest would fail without the widow's and daughter's consent, because the son is an heir.

What makes a will valid
Muslim law prescribes no rigid form - a wasiyyat can in principle be oral, written, or even made by clear gesture. But proving an oral will after death is extremely hard, so in practice a valid, defensible will in Pakistan should meet these standards:
| Requirement | Detail |
|---|---|
| Competent testator | Adult (18+), of sound mind, acting freely without coercion |
| Clear intention | The property and the beneficiary must be identifiable |
| In writing | Strongly advised - reduces disputes over authenticity |
| Two witnesses | Attested by at least two competent witnesses, ideally not beneficiaries |
| Within the one-third limit | Otherwise dependent on heir consent |
| Registration (optional) | Not mandatory under the Registration Act 1908, but recommended |
Registering the will with the Sub-Registrar is not legally required, but a registered will carries a strong presumption of genuineness and is much harder for a disgruntled heir to challenge as a forgery.
Changing or cancelling a will
A wasiyyat is fully revocable throughout the testator's life. You may amend it, replace it with a fresh will, or cancel it entirely, provided you are of sound mind. Revocation can be express (a later document) or implied (for example, gifting or selling the very property that was bequeathed). Because a later valid will overrides an earlier one, always date your will and destroy superseded copies to avoid confusion after death.
How the rules differ for non-Muslims
The one-third rule is a rule of Islamic law. It does not apply to non-Muslim citizens, whose wills are governed by the Succession Act 1925. A Christian, Hindu or Parsi testator in Pakistan can generally dispose of their entire estate by will and is free to favour any person, subject to the ordinary formalities of that Act. If a will needs to be proved and administered through the courts, an executor may seek probate; where there is no will, heirs obtain a succession certificate instead.
Frequently asked questions
Can a Muslim will away more than one-third?
Only if every legal heir consents after the testator's death. Without that consent, the portion above one-third fails and reverts to the heirs under Faraid.
Can I leave my house to my wife by will?
A wife is a legal heir, so a bequest to her is void unless all the other heirs consent after your death. Consider a lifetime gift (hiba) instead.
Is an oral will valid in Pakistan?
Muslim law allows it, but proving an oral will after death is very difficult. A written, witnessed and registered will is far safer.
Does a will avoid inheritance disputes?
Only partially. It controls at most one-third; the rest still follows fixed shares, and heirs can contest a will's authenticity or scope. Careful drafting reduces the risk.
What happens if I die without a will?
The entire net estate is distributed among your heirs strictly under Islamic inheritance law. Nothing goes to charities or non-heirs.
Can a gift (hiba) do what a will cannot?
Yes. A lifetime gift is not bound by the one-third cap or the heir restriction, which is why estate planning often combines gift, will and trust.
