Common Law trusts evolved within Christian legal tradition and sit uneasily with Sharia principles around inheritance and property. Muslim HNWI families often prefer structures with clear Sharia heritage. This is the 2026 guide to Sharia-compliant alternatives.
The core alternatives
1. Waqf (Islamic endowment)
- Traditional Islamic charitable or family endowment
- Founder irrevocably endows assets to a specific purpose (family support, charity, mosque, education)
- Trustee (Mutawalli) administers per founder's conditions
- Historically permanent; modern Waqf can have time limits
- Available in most GCC jurisdictions; UAE has modern Waqf regulations
2. Foundation structures (Sharia-compatible)
- ADGM and DIFC Foundations can be structured Sharia-compliant
- Purpose clause aligned with Islamic principles
- Beneficiary rights structured per Islamic inheritance rules
- Sharia Supervisory Board review recommended
- Most popular modern Sharia-compliant family wealth vehicle
3. Hibah (Gift during lifetime)
- Outright gift of assets during lifetime
- Not limited to one-third when made and delivered during healthy lifetime (gifts made during a final illness are treated like a bequest and capped at one-third)
- Registered formally for legal validity
- Simple but less flexible than ongoing structures
4. Wasiyah (Islamic will)
- Written will disposing of up to 1/3 of estate outside Sharia inheritance rules
- Remaining 2/3 distributed per Sharia (specified shares to specific relatives)
- Registered with UAE courts for enforceability
- Must be executed by Muslim witnesses per Sharia
5. Nominee or custodial structures
- Specific family member or professional trustee holds assets on behalf of family
- Less formal than Foundation or Waqf
- Can create ambiguity at succession; less recommended for significant wealth
Comparison matrix
| Structure | Sharia Compatibility | Modern Legal Framework | Flexibility | Privacy |
|---|---|---|---|---|
| Waqf | Native | Medium | Low (permanent) | Medium |
| Foundation | Adaptable | Strong | High | High |
| Hibah | Native | Strong | One-time | Low |
| Wasiyah | Native | Strong | Post-death only | Medium |
| Nominee | Neutral | Weak | Variable | Medium |
| Common Law Trust | Problematic | Strong (offshore) | Very High | High |
The modern Muslim HNWI approach
Based on 2026 practice, the typical structure for a Muslim HNWI family with USD 100M+ AUM:
- ADGM Foundation as primary wealth vehicle (structured Sharia-compliant)
- Individual holdings via operating SPVs for tax and operational flexibility
- Real estate holdings via dedicated SPV below the Foundation
- Wasiyah for each senior family member covering non-Foundation assets
- Annual Zakat calculation and payment from Foundation
- Educational or charitable Waqf separate from family wealth for philanthropy
- Sharia Supervisory Board review at structure design and on any material changes
Key pitfalls
- Treating Foundation like a Common Law trust without Sharia review
- Forgetting that Wasiyah only covers 1/3 of estate (remaining 2/3 goes per Sharia)
- Using Hibah without proper documentation (can be disputed at succession)
- Mixing Waqf purposes (family + charitable) without clear separation
- Not engaging qualified Islamic scholar for specific family circumstances
Worked Example
Consider a Saudi-UAE family with significant operating business and real estate holdings weighing a transition from an existing Cayman Trust to a Sharia-compliant structure. Suppose the family's Sharia Supervisory Board raises concerns about the Common Law trust concept and indicates a preference for a Foundation. A coherent design would be: (1) ADGM Foundation as primary vehicle with Sharia-aligned purpose and beneficiary provisions, (2) operating SPVs under the Foundation for business holdings, (3) a separate charitable Waqf for family philanthropy, (4) a Wasiyah for each family principal covering personal non-Foundation assets. An implementation of this scope would typically run 12 to 18 months, with setup costs spanning ADGM registration fees, legal drafting, Sharia Supervisory Board review, and SPV formation. The projected result: institutional governance, clear succession, and Sharia alignment. The lesson: Muslim HNWI families increasingly have access to structures that honor their religious framework without sacrificing institutional quality.

Frequently asked questions
What is a Sharia-compliant trust alternative?
The main Sharia-compliant alternatives to Common Law trusts are Waqf (Islamic endowment), Foundation structures (DIFC, ADGM, structured Sharia-compliant), Hibah (lifetime gift), Wasiyah (Islamic will), and nominee structures. Modern Muslim HNWI families typically prefer Foundation structures with Sharia Supervisory Board review.
What is a Waqf?
Waqf is a traditional Islamic endowment where a founder irrevocably dedicates assets to a specific purpose (family support, charity, mosque, education). A Mutawalli (trustee) administers per the founder's conditions. Historically permanent, though modern Waqf can have time limits. Available in most GCC jurisdictions.
Is a DIFC Foundation Sharia-compliant?
DIFC and ADGM Foundations can be structured Sharia-compliant by aligning the purpose clause, beneficiary arrangements, and distribution mechanisms with Islamic principles. Many Muslim families prefer the Foundation structure over Common Law trusts because the civil-law Foundation concept is more compatible with Sharia jurisprudence.
What is the difference between Hibah and Wasiyah?
Hibah is a gift made during the giver's lifetime, effective immediately. Wasiyah is an Islamic will that takes effect after death, covering up to 1/3 of the estate (the remaining 2/3 distributes per mandatory Sharia inheritance rules). Both require formal documentation for legal validity.
Do Muslims in UAE need a will?
Muslims in UAE are subject to Sharia inheritance rules by default. A Wasiyah (Islamic will) can dispose of up to 1/3 of the estate outside these rules. Non-Muslims can elect their home-country inheritance law via DIFC Wills or ADGM Wills. All HNWIs should have explicit wills and estate plans to avoid disputes at succession.
