Inheritance Law of Shia Law — Everything you need to know about with Illustrations

Question: How does Shia law of inheritance classify heirs, and what are the main categories of consanguine heirs?

Answer:

Introduction:

In Shia law of inheritance, heirs of a deceased Muslim are grouped based on their relationship to the deceased. These groups ensure a structured distribution of the estate, prioritizing close family members and dividing the estate among them systematically.

Classification of Heirs:

Shia inheritance law categorizes heirs into two primary groups:

1. Consanguine Heirs: These are heirs related to the deceased by blood.
2. Relations by Marriage: This includes the husband and wife.

Consanguine Heirs:

Consanguine heirs are further divided into three groups, each with two sub-groups. The priority is given to closer relatives, with the former groups excluding the latter. However, within each group, the heirs mentioned in the sub-groups inherit together without excluding each other.

Group I:

• Sub-group (i): Parents
• Sub-group (ii): Children and other lineal descendants, regardless of how far removed (e.g., grandchildren, great-grandchildren).

Group II:

• Sub-group (i): All grandparents, regardless of how far removed (e.g., great-grandparents).
• Sub-group (ii): Brothers and sisters and their descendants, regardless of how far removed (e.g., nephews, nieces, great-nephews, and great-nieces).

Group III:

• Sub-group (i): Paternal uncles and aunts of the deceased, as well as those of his parents and grandparents, regardless of how far removed.
• Sub-group (ii): Maternal uncles and aunts of the deceased, as well as those of his parents and grandparents, regardless of how far removed.

Sharers and Residuaries:

Shia inheritance law also classifies heirs into sharers and residuaries:

• Sharers: These are heirs entitled to a fixed share of the inheritance as specified in Islamic law (e.g., spouse, parents, children).
• Residuaries: These are heirs who inherit the remainder of the estate after the fixed shares have been distributed.

Absence of Distant Kindred:

Unlike Sunni inheritance law, Shia law does not recognize the category of distant kindred. In the absence of the primary consanguine heirs and relations by marriage, the estate would be distributed among the remaining consanguine heirs based on their proximity to the deceased.

Conclusion:

Shia law of inheritance provides a structured approach to estate distribution by categorizing heirs into consanguine heirs and relations by marriage, with further sub-divisions ensuring an orderly and equitable division of the estate. The absence of the distant kindred category simplifies the process, focusing on the closer familial relationships.

Question: Could you explain the sharers in Shia law of inheritance, including their entitlements and conditions for inheritance?

Answer:

Introduction:

In Shia law of inheritance, sharers are specific heirs who are entitled to a fixed share of the deceased’s estate. These shares are determined based on familial relationships and ensure that certain family members receive a portion of the inheritance as prescribed by Islamic law.

Sharers and Their Entitlements:

Sharers in Shia law of inheritance include both males and females, encompassing a variety of familial relationships:

1. Husband: Entitled to 1/4 of the estate in the presence of a lineal descendant (e.g., child), and 1/2 in the absence of such descendants.
2. Wife: Entitled to 1/8 of the estate in the presence of a lineal descendant, and 1/4 in the absence of such descendants.
3. Father: Entitled to 1/6 of the estate in the presence of a lineal descendant. If there is no descendant, the father inherits as a residuary.
4. Mother: Entitled to 1/6 of the estate in the presence of a lineal descendant, or with two or more full or consanguine brothers, or one such brother and two such sisters, or four such sisters, along with the father. In other cases, the mother receives 1/3 of the estate.
5. Daughter: Entitled to 1/2 of the estate in the absence of a son. If there is a son, she shares as a residuary.
6. Uterine Brother or Sister: Entitled to 1/6 of the estate in the absence of a parent or lineal descendant. The full sister inherits as a residuary, along with the full brother and also with the father’s father.
7. Full Sister: Entitled to 1/2 of the estate in the absence of a parent, lineal descendant, or full brother, or father’s father. The consanguine sister inherits as a residuary, along with the consanguine brother and also with the father’s father.
8. Consanguine Sister: Entitled to 1/2 of the estate in the absence of a parent, lineal descendant, full brother or sister, or consanguine brother, or father’s father.

Conditions for Inheritance:

• Normal Share: Each sharer’s entitlement to the estate is contingent upon specific conditions, primarily the presence or absence of lineal descendants or other designated relatives.
• Variation of Shares: If multiple heirs are present within a category, the distribution of the estate may vary based on the number and type of relatives present.

Conclusion:

Sharers in Shia law of inheritance ensure that close relatives receive a fixed portion of the deceased’s estate, with entitlements varying based on familial relationships and the presence of other eligible heirs. This structured approach ensures a fair distribution according to Islamic principles, prioritizing familial ties in estate division.

Question: Explain the provisions related to surviving spouses (husband and wife) under Shia law of inheritance, including their entitlements, conditions for inheritance, and rights to the residue.

Answer:

Introduction:

Under Shia law of inheritance, surviving spouses (husband and wife) are entitled to specific shares of the deceased’s estate, which vary depending on the presence or absence of certain heirs and conditions.

Surviving Spouse (Husband and Wife) Entitlements:

1. Husband:

• In the presence of lineal descendants (e.g., children), the husband is entitled to 1/4 (one-fourth) of the estate.
• In the absence of lineal descendants, the husband’s share increases to 1/2 (one-half) of the estate.
• The share of the husband is fixed and does not vary with the presence of other relatives beyond lineal descendants.

2. Wife:

— When a Shia female dies, her husband is entitled to inherit:

• 1/8 (one-eighth) of the estate in the presence of lineal descendants.
• 1/4 (one-fourth) of the estate in the absence of lineal descendants.

— A childless widow inherits movable property only. She does not inherit immovable property (land), but is entitled to 1/4 share in the value of trees or buildings standing upon it.

Rights to the Residue:

• Husband: If a Shia female dies and her only heir is her husband, he takes half (1/2) as a sharer, and the remaining half goes under the doctrine of return (radd).
• Widow: The older view was that a widow is entitled to only 1/4 share as a Quranic heir, and the rest of the property would pass to the government under the doctrine of escheat. However, the later view upheld by courts is that a widow is entitled to 1/4 share and also to the rest of the property under the doctrine of return.

Additional Entitlements:

• Parents: Both the father and mother inherit alongside the spouse and descendants. The father inherits 1/6 (one-sixth) in the presence of lineal descendants, or as a residuary in their absence. The mother’s share is 1/6 in the presence of lineal descendants, or 1/3 in other cases.
• Lineal Descendants: In Shia law, all lineal descendants are grouped together and inherit together, subject to rules of exclusion and representation. For example, a daughter inherits as a sharer in the absence of a son. If there are multiple daughters, they inherit two-thirds (2/3) of the property. Sons inherit as residuaries.

Conclusion:

The provisions under Shia law ensure that surviving spouses, whether husband or wife, receive a defined share of the deceased’s estate based on the presence or absence of lineal descendants and other heirs. This structured approach aims to distribute inheritance fairly while adhering to Islamic principles of familial rights and responsibilities.

Question: Illustrate the distribution of inheritance under Shia law with examples of different scenarios involving various heirs.

Answer:

Introduction:

The distribution of inheritance under Shia law follows specific rules that consider the presence of various heirs, their degrees of relationship to the deceased, and the principles of representation and exclusion.

Illustrations:

Illustration (i): A Shia Muslim, A, dies and is survived by his parents, M and F, a son S, and two daughters D1 and D2.

— Distribution:

• M and F each take one-sixth (1/6) as sharers.
• D1 and D2 inherit as residuaries with S, with shares as follows:
• M = 1/6
• F = 1/6
• S = 1/3
• D1 = 1/6
• D2 = 1/6

Under Sunni law, the distribution would be identical.

Illustration (ii): A Shia Muslim, A, dies and is survived by his parents M and F and two sons of his daughter, DS1 and DS2.

— Distribution:

• F and M each take one-sixth (1/6) as sharers.
• DS1 and DS2 represent their mother and take two-thirds (2/3) together, divided equally:
• F = 1/6
• M = 1/6
• DS1 = 1/3
• DS2 = 1/3

Under Sunni law, the mother would take one-third (1/3) and the father two-thirds (2/3) as a residuary. Daughter’s sons would not inherit in presence of sharers.

Illustration (iii): A Shia Muslim, A, dies and is survived by two daughters of a predeceased son, SD1 and SD2, and three sons of a predeceased daughter, DS1, DS2, and DS3.

— Distribution:

• All descendants are in the same degree of relationship.
• Property is divided per stirpes, with the branch of the deceased son taking two-thirds (2/3) and the branch of the daughter one-third (1/3).
• SD1 and SD2 each take one-third (1/3).
• DS1, DS2, and DS3 each take one-ninth (1/9):
• SD1 = 1/3
• SD2 = 1/3
• DS1 = 1/9
• DS2 = 1/9
• DS3 = 1/9

Under Sunni law, the three sons of the daughter would be excluded, and the two daughters of the son would take two-thirds (2/3) as sharers, with the surplus going to return.

Illustration (iv): A Shia male, A, dies and is survived by two sons of one predeceased son, SS1 and SS2, and three sons of another predeceased son, S1S1, S1S2, and S1S3.

— Distribution:

• Property divided into two equal parts, one for each branch.
• SS1 and SS2 each take one-fourth (1/4).
• S1S1, S1S2, and S1S3 each take one-sixth (1/6):
• SS1 = 1/4
• SS2 = 1/4
• S1S1 = 1/6
• S1S2 = 1/6
• S1S3 = 1/6

Under Sunni law, grandsons would take one-fifth (1/5) each, following per capita succession.

Illustration (v): A Shia Muslim, A, dies leaving behind two sons, S1 and S2, and two sons of a predeceased son, SS1 and SS2.

— Distribution:

• Due to the principle of nearer blood excluding the remoter, the grandsons (SS1 and SS2) are excluded.
• S1 and S2 each take one-half (1/2) of the property.

Conclusion:

These illustrations demonstrate the application of Shia inheritance laws, showing how the shares of different heirs are determined based on their relationships to the deceased, with emphasis on the principles of representation and exclusion. The differences between Shia and Sunni laws are also highlighted, particularly in the treatment of distant kindred and the distribution of shares among lineal descendants.

Question: What are the rules for inheritance among the second-class heirs under Shia law?

Answer:

Introduction:

Under Shia law, when a deceased Muslim has no surviving heirs of the first class (parents, children, and other lineal descendants), the second-class heirs inherit the property. This class includes grandparents, brothers and sisters, and their descendants, who inherit along with any surviving spouse.

Heirs of Second Class:

Grandparents:

• Grandparents can be either paternal or maternal and take the property based on the following rules:

1. Grandparents inherit the share that would have been allotted to the parents through whom they are related to the deceased. The division is in the ratio of 2:1 for males to females on the paternal side and equal portions on the maternal side.
2. A nearer grandparent excludes a remoter grandparent.
3. On the failure of nearer grandparents, the remoter grandparents inherit according to the same rules.
4. When grandparents inherit with the brothers and sisters of the deceased or their descendants, a paternal grandfather is counted as a full or consanguine brother, and a paternal grandmother as a full or consanguine sister. A maternal grandfather is counted as a uterine brother, and a maternal grandmother as a uterine sister.

Illustrations:

Illustration (i): A Shia Muslim, A, dies and is survived by one paternal grandfather (FF) and one maternal grandfather (MF).

— Distribution:

• The mother’s share would have been one-third (1/3) and the father’s two-thirds (2/3).
• MF (mother’s father) takes the one-third (1/3) share of the mother.
• FF (father’s father) takes the two-thirds (2/3) share of the father.

— Shares:

• MF = 1/3
• FF = 2/3

Illustration (ii): The survivors of a Shia Muslim, A, are his maternal grandmother (MM), father’s mother (FM), and father’s father (FF).

— Distribution:

• MM takes one-third (1/3).
• FF and FM together take two-thirds (2/3) and divide it in a 2:1 ratio:

— Shares:

• MM = 1/3
• FF = 4/9
• FM = 2/9

Illustration (iii): The survivors of a Shia male, A, are his mother’s mother (MM), mother’s father (MF), father’s mother (FM), and father’s father (FF).

— Distribution:

• The maternal side gets one-third (1/3), equally shared by MF and MM.
• The paternal side gets two-thirds (2/3), divided in a 2:1 ratio between FF and FM:

— Shares:

• MM = 1/6
• MF = 1/6
• FF = 4/9
• FM = 2/9

Conclusion:

The rules for inheritance among second-class heirs under Shia law ensure that the property is distributed among surviving grandparents, brothers and sisters, and their descendants. The principles of representation and exclusion determine the specific shares, and the division between paternal and maternal sides follows set ratios, ensuring an equitable distribution among the eligible heirs.

Question: What are the rules for inheritance among brothers, sisters, and their descendants under Shia law?

Answer:

Introduction:

Under Shia law, the rules for inheritance among brothers, sisters, and their descendants vary based on their relationship to the deceased and the presence of other heirs. These rules ensure that the property is distributed fairly among the surviving siblings and their descendants.

Brothers, Sisters, and their Descendants:

Brothers, sisters, and their descendants inherit along with the grandparents of the deceased, if present. In their absence, the inheritance follows these rules:

1. Full Sister:

• A full sister is a sharer in the absence of a full brother, parents, father’s father, children, or other lineal descendants.
• She takes half (1/2) of the property if alone and two-thirds (2/3) if more than one full sister is present.

2. Full and Consanguine Brothers:

• Full and consanguine brothers inherit as residuaries.

3. Full Sister with a Full Brother:

• With a full brother, a full sister does not inherit as a sharer but becomes a residuary with him, taking a share equal to half of his share.

4. Exclusion by Full Siblings:

• Full blood brothers and sisters exclude consanguine brothers and sisters.

5. Consanguine Sister:

• A consanguine sister inherits as a sharer, taking a fixed half (1/2) share if alone and two-thirds (2/3) if there are two or more consanguine sisters.
• With a consanguine brother, she inherits as a residuary, taking a share equal to half of his share.

6. Uterine Brothers and Sisters:

• Uterine brothers and sisters inherit as sharers and are not excluded by full or consanguine siblings.
• The share of one uterine brother or sister is one-sixth (1/6), and if there are more, they collectively take one-third (1/3).

Illustrations:

Illustration (i):

— Scenario: A Shia Muslim, H, is survived by his widow (W), one full brother (FB), a full sister (FS), and one consanguine brother (CB).

— Distribution:

• The widow (W) takes one-fourth (1/4) as there are no children or lineal descendants.
• The consanguine brother (CB) is excluded in the presence of a full brother (FB).
• The full sister (FS) takes the property as a residuary, not as a sharer, due to the presence of the full brother (FB).
• The remaining three-fourths (3/4) of the property is divided between the full brother and full sister in a 2:1 ratio.

— Shares:

• W = 1/4
• FB = 1/2
• FS = 1/4

Illustration (ii):

— Scenario: The survivors of a Shia Muslim woman, W, are her two full brothers (FB1 and FB2), one full sister (FS), and her husband (H).

— Distribution:

• The husband (H) takes half (1/2) of the property.
• The remaining half (1/2) is taken by the brothers and sister in a 2:1 ratio.

— Shares:

• H = 1/2
• FB1 = 1/5
• FB2 = 1/5
• FS = 1/10

Illustration (iii):

— Scenario: The survivors of a Shia Muslim, H, are his full brother (FB), a uterine brother (UB), a uterine sister (US), and the widow (W).

— Distribution:

• The widow (W) takes one-fourth (1/4).
• The uterine brother and sister collectively take one-third (1/3) and divide it equally.
• The remaining portion is taken by the full brother (FB).

— Shares:

• W = 1/4
• UB = 1/6
• US = 1/6
• FB = 5/12

Conclusion:

The rules for inheritance among brothers, sisters, and their descendants under Shia law are designed to ensure a fair distribution of property based on the presence of other heirs and the specific relationships to the deceased. These rules help maintain a structured and equitable approach to inheritance within the family.

Question: How do the descendants of brothers and sisters inherit property under Shia law?

Answer:

Introduction:

Under Shia law, the inheritance of property by the descendants of brothers and sisters follows specific rules. These rules are designed to ensure that the property is distributed fairly among the descendants based on their degree of relationship to the deceased.

Descendants of Brothers and Sisters:

The descendants of brothers and sisters of the deceased inherit the property according to the following rules:

1. Exclusion Based on Degree:

• A descendant nearer in degree excludes the remoter descendant.

2. Rule of Representation:

• The shares of the children and other descendants of brothers and sisters are calculated based on the rule of representation.

3. Children of Brothers and Sisters:

• Children of a brother or a sister collectively take the share of the respective parent through whom they are related to the deceased.
• Children of a full or consanguine brother take the share their father would have taken if alive, divided according to the rule of males taking a double portion than females.
• Children of a full or consanguine sister take the share their mother would have taken if alive, divided such that females take half of the corresponding male counterpart.
• Children of a uterine brother or uterine sister take the share their parent would have taken as a sharer, divided equally among themselves regardless of sex.

4. Grandchildren:

• If no child of a brother or sister is present, the property passes to the grandchildren of such brother or sister, divided according to the above-mentioned rules.

Illustrations:

Illustration (i):

— Scenario: The survivors of a Shia male, A, are his full brother’s son (FBS), two daughters of a full sister (FSD1 and FSD2), and a uterine brother’s son (UBS).

— Distribution:

• The son of the uterine brother takes the share his father would have taken as a sharer (1/6).
• The remaining five-sixths (5/6) is divided between the branches of the full brother and full sister in a 2:1 ratio.

— Shares:

• UBS = 1/6
• FBS = 5/9
• FSD1 = 5/36
• FSD2 = 5/36

Illustration (ii):

• FM = 2/9

Conclusion:

The rules governing the inheritance of property by the descendants of brothers and sisters under Shia law ensure that the property is fairly distributed based on the relationship and degree of kinship to the deceased. These rules help maintain an equitable approach to inheritance within the extended family.

Question: What is the order of succession and rules for inheritance by third-class heirs under Shia law?

Answer:

Introduction:

In Shia inheritance law, when there are no heirs from the first or second classes, the property passes to the third-class heirs. This class includes uncles and aunts of the deceased, their parents, grandparents, and their descendants. The rules ensure that the property is distributed equitably among these relatives based on their degree of relationship to the deceased.

Third-Class Heirs:

1. Order of Succession:

— Paternal and Maternal Uncles and Aunts:

• They are the primary inheritors in the absence of first and second-class heirs.

— Descendants of Uncles and Aunts:

• The nearer in degree excludes the remoter descendants.

— Uncles and Aunts of Parents:

• Paternal and maternal uncles and aunts of the parents of the deceased.

— Descendants of Uncles and Aunts of Parents:

• They inherit based on the rule of nearer descendants excluding the remoter ones.

— Uncles and Aunts of Grandparents:

• Paternal and maternal uncles and aunts of the grandparents of the deceased.

— Descendants of Uncles and Aunts of Grandparents:

• They follow the same rule of nearer descendants excluding the remoter ones.

— Remoter Uncles and Aunts:

• Remoter uncles and aunts and their descendants inherit in the same order.

2. Rules of Inheritance:

— Division by Paternal and Maternal Sides:

• The property is divided into two parts: two-thirds to the paternal side and one-third to the maternal side.

— Paternal Side:

• Uterine Paternal Uncles and Aunts: They take one-sixth if only one is present and one-third if more than one is present, divided equally among them.
• Full Paternal Uncles and Aunts: They take the residue in a 2:1 ratio, respectively.
• Consanguine Paternal Uncles and Aunts: If full paternal uncles and aunts are not present, the property goes to consanguine paternal uncles and aunts, divided in a 2:1 ratio.

— Maternal Side:

• Uterine Maternal Uncles and Aunts: They take one-sixth if one is present, and one-third if two or more are present, divided equally among them.
• Full Maternal Uncles and Aunts: They share equally, and failing them, consanguine maternal uncles and aunts share equally.

— Descendants:

• If no uncles and aunts are present, their descendants inherit the property based on the rules of representation.

Illustrations:

Illustration (i):

— Scenario: The survivors of a Shia male are his full paternal uncle and a maternal aunt.

— Distribution:

• The full paternal uncle takes two-thirds (2/3), and the maternal aunt takes one-third (1/3).

Illustration (ii):

— Scenario: A Shia male dies and is survived by his full paternal uncle, a full paternal aunt, and a full maternal uncle.

— Distribution:

• The full paternal uncle and aunt together take two-thirds (2/3) with the uncle taking four-ninths (4/9) and the aunt taking two-ninths (2/9). The full maternal uncle takes one-third (1/3).

Illustration (iii):

— Scenario: A Shia male dies and is survived by a son of his full paternal uncle and a daughter of a full maternal aunt.

— Distribution:

• The son of the full paternal uncle takes two-thirds (2/3), and the daughter of the full maternal aunt takes one-third (1/3).

Conclusion:

The rules governing the inheritance by third-class heirs under Shia law ensure that the property is fairly distributed among the uncles, aunts, and their descendants based on their relationship to the deceased. This structured approach helps maintain equity and clarity in the inheritance process.

Question: What are the doctrines of return, increase (Aul), and escheat under Shia inheritance law?

Answer:

Introduction:

Shia inheritance law has specific doctrines governing the distribution of property when certain conditions are met. These doctrines include the doctrine of return, the doctrine of increase (Aul), and escheat. Understanding these doctrines is crucial for comprehending how property is allocated among heirs.

Doctrine of Return:

The doctrine of return addresses the scenario where, after satisfying the claims of the sharers, some residue is left, but no residuary heir is present. This excess share reverts to the sharers under specific rules.

Rules of Return:

1. Exclusion of Surviving Spouse:

• The surviving spouse (husband or wife) is not entitled to any return if any other heir is present. However, if no other sharer is present, the husband or wife can take the return.

2. Exclusion of Mother:

— The mother of the deceased cannot claim the return in the presence of the father, daughter, and:

• Two or more full or consanguine brothers; or
• One such brother and two such sisters; or
• Four such sisters.

— In these cases, the surplus is taken by the father and the daughter in proportion to their shares.

1. Exclusion of Uterine Siblings:

• In the presence of a full sister, a uterine brother or uterine sister cannot take the surplus by return.

Doctrine of Increase (Aul):

The doctrine of increase, or Aul, addresses situations where the sum total of the shares of all heirs exceeds unity. Unlike some other schools of Islamic law, Shia law does not recognize the doctrine of increase and the consequent proportional deduction of shares by increasing the denominator of the sum total. Instead, if the sum total exceeds unity, the excess share is deducted from the share of the daughters or full or consanguine sisters.

Illustration of Increase:

— Scenario: The survivors of a Shia female are her parents (F and M), two daughters (D1 and D2), and her husband (H).

— Distribution:

• F and M each receive one-sixth (1/6).
• H receives one-fourth (1/4).
• D1 and D2 together are entitled to two-thirds (2/3).
• The sum total of these shares is: 1/6 + 1/6 + 1/4 + 2/3 = 15/12
• The excess share is 3/12 or 1/4. This one-fourth (1/4) is deducted from the share of the daughters: 2/3–1/4 = 5/12
• Each daughter receives 5/24.

Escheat:

In the absence of all heirs, the property of a Shia Muslim escheats to the government. This doctrine ensures that the property does not remain ownerless and is instead taken over by the state.

Conclusion:

The doctrines of return, increase (Aul), and escheat in Shia inheritance law provide a structured approach to the distribution of property in various scenarios. The doctrine of return reverts excess shares to sharers under specific conditions, while the doctrine of increase addresses the excess sum total by deducting from certain shares. Finally, escheat ensures that property without heirs passes to the government, maintaining order and continuity in property ownership.
