The Role of a Wasiat in Muslim Estate Planning
- August 7, 2026
A wasiat is a will made under Muslim law, allowing a Muslim to direct that part of their estate be given to chosen recipients after death or keeping within faraid principles. In Singapore, a wasiat operates alongside faraid the fixed-share system of Muslim inheritance and within limits set by Muslim law. Used thoughtfully, it can be a helpful part of estate planning.
The key points:
- A wasiat allows the appointment of executor(s) to the estate.Â
- A wasiat gives a Muslim the option to make a bequest of up to one-third of their estate to persons who are not beneficiaries under faraid.Â
- Bequests to individuals who are non-heirs or in different proportions other than faraid are generally not permitted through a wasiat unless the other heirs consent. This can be done through a Deed of Family Arrangement.
- A wasiat does not replace faraid; the remainder of the estate is still distributed according to faraid.
- It can be used for purposes such as providing for non-heirs or making charitable gifts (wakaf or other causes), subject to the applicable rules.
What a wasiat can and cannot do
The distinguishing feature of a wasiat is the one-third limit. Under Muslim law, a person may generally bequeath up to one-third of their estate to recipients who would not otherwise inherit under faraid for example, an adopted child, a non-Muslim relative, or a charitable cause. Bequeathing one-third of the estate to non-beneficiaries, however, is not compulsory.Â
Bequests that exceed one-third, or that are made to existing fixed heirs, typically require the consent of the other heirs to take effect. This is an important distinction, because it means a wasiat cannot simply be used to redistribute the whole estate however one wishes the remainder still passes according to faraid.
How a wasiat fits with faraid
It helps to think of the estate in two parts:
- The wasiat portion up to one-third, which can be directed to chosen non-heirs within the rules.
- The remainder distributed among the fixed heirs according to faraid.
Because the two work together, a wasiat is best understood as a way to make specific, permitted provisions, not as an alternative to the faraid system.
Common reasons people make a wasiat
Individuals may consider a wasiat to:
- provide for someone who is not a beneficiary, such as an adopted child or a foster relative;
- give to charity or a religious cause; or
- set out wishes clearly to reduce uncertainty for the family.
Each of these has conditions attached, and the suitability of a wasiat depends on the person’s family situation and assets.
Practical considerations in Singapore
A wasiat should be prepared carefully so that it is valid and reflects the maker’s intentions within Muslim law. It is also worth coordinating a wasiat with other arrangements such as CPF nominations, jointly held property, and any lifetime gifts (hibah) because these may be treated differently from the estate distributed on death. However, hibah or nuzriah may not necessarily be recognised in Singapore. Our services will provide you with a better understanding of these estate-planning tools.
Key takeaways
A wasiat, or a Muslim will, allows up to one-third of an estate to be given to non-heirs, working alongside, not instead of faraid. One can also choose not to bequeath the one-third to non-beneficiaries. It is a useful planning tool for specific, permitted purposes, but it operates within clear limits. Understanding those limits is the first step to planning an estate in a way that is both meaningful and consistent with Muslim law.
