A Shariah distribution that survives an English probate registry
The religious calculation and the legal instrument are two different problems. Most Islamic wills sold in the UK solve only the first.
An Islamic will is valid in England and Wales because English law permits testators to distribute their estate as they wish. It must meet Wills Act 1837 formalities, and it remains open to a claim under the Inheritance (Provision for Family and Dependants) Act 1975. A properly drafted Shariah-compliant will therefore does three things: it states the farāʾiḍ shares as enforceable dispositions, it uses the one-third wasiyyah deliberately, and it anticipates the 1975 Act rather than pretending it does not exist.
Two documents pretending to be one
An Islamic will has to satisfy two systems at once. Under Shariah, the estate must reach the right heirs in the right proportions. Under English law, the document must be a formally valid will that a probate registry will accept and an executor can administer without a court application.
Templates sold online typically get the first part approximately right and the second part wrong. The most common defects we see are a distribution expressed as a wish rather than a gift; a gift of “one third to charity” with no mechanism if the charity has ceased to exist; no substitutional provision if an heir predeceases; witnesses who are also beneficiaries, voiding their gifts under s.15 of the Wills Act 1837; and no residuary clause at all - which means part of the estate falls into intestacy and is distributed under statutory rules that bear no relation to farāʾiḍ.
The failure mode nobody expects. A defective Islamic will does not produce a slightly-off Islamic distribution. It produces an English intestacy: spouse takes the statutory legacy and half the residue, children the rest, parents and siblings nothing. That is further from farāʾiḍ than having no religious intention at all.
The one-third and the two-thirds
Classical jurisprudence separates the estate into the wasiyyah - up to one third, freely bequeathable to non-heirs or to charity - and the remaining two thirds, distributed to the Qur'anic heirs in fixed fractional shares. Rendering that in an English will means being explicit about the order of operations.
| Step | How it appears in the will |
|---|---|
| Funeral and burial costs | An express direction, ahead of all gifts, with the burial instructions in the will and repeated in an accessible letter - a will is often not read until after burial. |
| Debts, including religious obligations | Ordinary debts, plus any unpaid zakāt or unperformed obligations you wish treated as a debt of the estate, expressed as a binding direction rather than a hope. |
| Wasiyyah (up to one third) | Specific pecuniary or fractional gifts, capped at one third of the net estate after debts, with a mechanism for what happens if a gift fails. |
| Farāʾiḍ shares (the residue) | Residue divided in the fixed fractions applicable to the heirs who in fact survive - drafted as a formula with substitution, not as a fixed list that becomes wrong the moment the family changes. |
The 1975 Act problem, handled honestly
The Inheritance (Provision for Family and Dependants) Act 1975 gives certain people the right to ask the court for reasonable financial provision from an estate, regardless of what the will says. A surviving spouse is entitled to the most generous standard - what is reasonable in all the circumstances, not merely what is needed for maintenance.
Because a farāʾiḍ distribution frequently gives a widow one eighth of the estate, the exposure is real. Ignoring it does not remove it; it simply moves the argument to a courtroom, after death, between grieving relatives. We deal with it in three ways: structuring lifetime provision so the estate is not the only thing supporting the survivor; documenting reasons in a letter of wishes that the court can weigh; and where appropriate, using the wasiyyah third to top up provision in a way that is both religiously permissible and legally protective.
Cross-border Islamic estates
Most of our Islamic-will clients also have assets outside the UK - property in Pakistan, India, Bangladesh or Turkey, an account or a business in the Gulf, sometimes an EU property. Each one raises its own question about whether local law will apply Shariah, a civil code, or the deceased's national law. In the UAE, the DIFC and ADGM registered-will regimes matter enormously for non-Muslims and are largely unavailable to Muslims. This is where the Islamic-will work and the cross-border work stop being separate services.
Our role, and its limits
We are not a religious authority and we do not issue rulings. Where the correct farāʾiḍ shares depend on a point of jurisprudence - the school you follow, the treatment of a particular relative, whether a bequest to an heir is permissible - we work from the determination of your scholar, mosque or institution. Our contribution is to turn that determination into a document the English legal system will enforce exactly as written.
Common questions
Is an Islamic will legally valid in England and Wales?
Yes, provided it is drafted as an English will. English law gives testators near-complete freedom of disposition, so nothing prevents you directing that your estate be divided according to farāʾiḍ. Validity depends on the Wills Act 1837 formalities - in writing, signed by the testator with the intention of giving effect to it, and witnessed by two people present at the same time, neither of whom may benefit. The religious basis of the distribution is legally irrelevant to validity.
What is the one-third rule?
Classical Islamic law permits a bequest (wasiyyah) of up to one-third of the net estate to persons who are not Qur'anic heirs, or to charity, with the remaining two-thirds distributed among the fixed heirs according to farāʾiḍ. Bequests beyond the third, or to an existing heir, traditionally require the consent of the other heirs after death. In an English will that structure is expressed as ordinary testamentary gifts, so it must be drafted to produce the intended result whether or not consent is later given.
Can I disinherit someone under an Islamic will in the UK?
Not reliably, and this is the point most often missed. The Inheritance (Provision for Family and Dependants) Act 1975 allows a spouse or civil partner, a former spouse who has not remarried, a child, someone treated as a child of the family, and anyone maintained by the deceased, to apply to the court for reasonable financial provision - whatever the will says. A farāʾiḍ distribution can leave a surviving spouse or a non-Muslim child with materially less than the court might award. That risk is managed by anticipating it in the drafting and in a letter of wishes, not by ignoring it.
Do I need a separate will for assets in a Muslim-majority country?
Usually yes. Many jurisdictions apply their own succession law to land within their territory, and some apply Shariah by default to a Muslim's estate regardless of the will. The UAE is the clearest example: DIFC and ADGM operate registered-will regimes that allow non-Muslims to opt out of default Shariah succession for UAE assets, while a Muslim's UAE estate is generally governed by Shariah. The right structure depends on your faith, nationality and where the assets sit.
How are the fixed shares calculated?
Farāʾiḍ allocates fixed fractional shares to Qur'anic heirs - spouse, parents, children and, depending on who survives, siblings and more distant relatives - with residue passing to agnatic heirs, and adjustment doctrines (ʿawl and radd) applied where the fractions over- or under-fill the estate. Which school of jurisprudence you follow can change the outcome. We work from your scholar's or institution's determination rather than substituting our own: our role is to render the determination as an enforceable English disposition.
