Islamic Inheritance Calculator (UK) – Preview

This page gives you two ways to calculate inheritance depending on what you need. Shares Only shows Islamic inheritance shares as percentages for each individual heir — useful for Will planning, family discussions, or general awareness. Probate/Post-Death estimates amounts each person receives from the residuary estate after funeral costs, debts (including mahr if owed), and wasiyyah (bequests).

Switch instantly between “Shares Only” and “Probate/Post-Death”.

Important: This tool is educational. Complex estates and UK-specific issues (pensions, joint property, trusts, overseas assets, dependants’ claims, etc.) require solicitor and scholarly review.

Shares Only

No estate value needed. Enter family members and calculate the share structure for each individual.

Used to determine spouse share (husband/wife).

If the deceased is male you can select multiple wives.

Wives share the wife fraction equally.

If sons exist, children inherit residuary with 2:1 ratio.

If no sons, daughters may receive 1/2 or 2/3 fixed shares.

If father survives, he may take a fixed share and/or residue.

Mother share varies with descendants and siblings (special cases exist).

Shown when father is not alive; treated as father in this simplified tool.

Appears when there are no descendants and no father/grandfather (simplified).

Appears when siblings are 0 and closer heirs are absent (simplified).

Appears when nephews/nieces are 0 and closer heirs are absent (simplified).

Islamic inheritance FAQs (UK)

General information for England & Wales. Always take solicitor and scholarly advice for your circumstances.

FAQ 1 Do Islamic inheritance rules apply automatically in the UK?
In England & Wales, Islamic inheritance rules do not apply automatically. Distribution happens under a valid Will, or under intestacy rules if there is no valid Will. An Islamic Will is drafted to satisfy UK formalities while expressing Sharia-compliant distribution.
FAQ 2 What is the 1/3 wasiyyah and who can receive it?
In many Sunni approaches, up to one-third of the net estate (after funeral costs and debts) may be gifted to non-heirs (e.g., charities). Bequests above one-third typically require heirs’ consent. UK drafting and asset types also matter.
FAQ 3 Why do pensions and joint property sometimes not follow the Will?
Some assets can pass outside the estate (e.g., certain pensions via nominations, joint property by survivorship, insurance in trust). A solicitor can help align Sharia intentions with the legal route each asset takes.
FAQ 4 Can I leave everything to my spouse or children?
Under faraid, eligible heirs often have fixed entitlements and the remainder is distributed in a defined order. If you want a different distribution, take advice on Sharia permissibility and UK consequences.
FAQ 5 When should I get specialist help?
If you have overseas assets, business interests, second marriage, step/adopted children, trusts, missing heirs, or disputes, get tailored advice. Calculators help with orientation, not final confirmation.
Practical tip: Pair calculator results with a UK-valid Islamic Will and an asset review (pensions, nominations, joint ownership, trusts).
