Inheritance disputes are among the most emotionally charged and legally complex cases in Pakistan. The distribution of a deceased person's estate is governed by Islamic law (Shariah) as codified through the Muslim Personal Law (Shariat) Application Act, 1962, and interpreted through decades of Superior Court jurisprudence.

1. Fundamental Principles

A. Mandatory Distribution

Unlike common law systems where a person can freely distribute their entire estate through a will, Islamic inheritance law imposes mandatory fixed shares for specified heirs. A Muslim cannot disinherit a legal heir or alter the Quranic shares through a will.

B. The One-Third Rule for Wills

A Muslim may make a will (wasiyat) for up to one-third (1/3) of their estate in favour of non-heirs only (e.g., charities, friends, distant relatives who are not legal heirs). A bequest exceeding one-third, or a bequest in favour of a legal heir, is void unless all other heirs unanimously consent.

C. Debts and Funeral Expenses First

Before any distribution, the estate must satisfy:

1. Funeral and burial expenses.
2. Outstanding debts of the deceased.
3. Bequests under the will (up to one-third).
4. Only the remaining estate is divided among heirs according to Quranic shares.

2. Categories of Heirs

Islamic inheritance law classifies heirs into three categories:

A. Sharers (Ashab al-Furud) — Fixed-Share Heirs

These heirs receive predetermined fractions as specified in the Holy Quran (Surah An-Nisa, 4:11-12):

B. Residuaries (Asabat) — Remainder Heirs

After the sharers receive their fixed portions, the remaining estate goes to the residuary heirs. The most common residuaries are:

• Son: Receives the residue. When inheriting alongside daughters, the son receives double the share of the daughter (Quran 4:11: "for the male, what is equal to the share of two females").
• Father: Becomes a residuary if the deceased has no sons.
• Full Brother and Paternal Brother: Residuaries in the absence of sons and father.

C. Distant Kindred (Dhawil Arham)

If no sharers or residuaries exist, the estate passes to distant relatives such as maternal grandfather, maternal uncle, daughter's children, and sister's children.

3. Daughter's Right to Inherit

The deprivation of daughters from inheritance is unfortunately widespread in rural Pakistan, despite being explicitly prohibited by both the Quran and Pakistani law.

A. Legal Position

• A sole daughter inherits 1/2 of the estate.
• Two or more daughters (without a brother) inherit 2/3 collectively.
• When a son and daughter inherit together, the son gets twice the daughter's share — but the daughter's share is never zero.

B. Criminal Penalty

The Prevention of Anti-Women Practices (Criminal Law Amendment) Act, 2011 inserted Sections 498-A and 498-B into the PPC, making it a criminal offence to:

• Deprive a woman of her inheritance through coercion, deceit, or forgery.
• Force a woman to surrender her inherited property. The penalty is imprisonment of 5 to 10 years and/or a fine of up to 1 million PKR.

C. How to Challenge Deprivation

A daughter who has been deprived of her inheritance can:

1. File a Suit for Declaration and Possession in Civil Court.
2. File a complaint under Section 498-A PPC at the police station.
3. Apply to the Revenue Department to challenge a fraudulent mutation (Intaqal) that excluded her name.

4. Widow's Right to Inherit

A. Fixed Share

• Widow with children: 1/8 of the estate.
• Widow without children: 1/4 of the estate.
• If there are multiple widows, they collectively share the 1/8 or 1/4 equally.

B. Mehr (Dower) Priority

The widow's unpaid Mehr is treated as a debt of the deceased and must be paid from the estate before any inheritance distribution begins. This means the widow effectively receives her Mehr plus her Quranic share.

5. Common Inheritance Disputes

A. Oral Partition and Denial of Share

In many families, property is divided orally without formal documentation. Years later, one heir may deny that the partition ever happened. Without written evidence, courts apply the principle of best available evidence under the Qanun-e-Shahadat Order.

B. Fraudulent Mutations (Intaqal)

A common tactic is for one heir (typically a son) to execute a fraudulent mutation in the Revenue records, transferring the deceased's property entirely to himself and excluding daughters and widows. This can be challenged through:

• A suit for cancellation of the fraudulent mutation in Civil Court.
• A revision petition before the Board of Revenue.

C. Gifts (Hiba) Made to Defeat Inheritance

A person may gift all their property (Hiba) to one child during their lifetime to prevent other heirs from inheriting. Under Islamic law, a valid Hiba requires three essentials: (1) declaration by the donor, (2) acceptance by the donee, and (3) delivery of possession. A gift made during the last illness (maraz-ul-maut) is treated as a will and subject to the one-third rule.

6. How to Obtain a Succession Certificate

To legally access a deceased person's bank accounts, shares, or movable assets, the legal heirs must obtain a Succession Certificate from the Civil Court under Sections 370-373 of the Succession Act, 1925.

Process:

1. File a petition listing all legal heirs and the deceased's assets.
2. Publish notice in a local newspaper.
3. Wait 45 days for objections.
4. If no objections, the court issues the certificate.
5. Present the certificate to banks, companies, and institutions to claim assets.

7. Practical Advice

1. Make a will (for the one-third portion). Even though two-thirds is fixed by Shariah, the one-third discretionary portion allows you to benefit charitable causes or non-heirs.
2. Register all property mutations promptly after a death to prevent fraudulent transfers.
3. Keep copies of all land records, bank documents, and the deceased's CNIC.
4. Consult a qualified advocate and Shariah scholar for complex inheritance calculations, especially when multiple categories of heirs coexist.
