Two sets of rules, and only one of them governs the estate
The UAE runs personal status by religion, and inheritance sits inside personal status. That one design choice is why almost every answer below arrives in two versions, and why a reader who does not know which version is theirs cannot use any of them.
The Sharia track is statute, not custom. Federal Decree-Law 41/2024, the Personal Status Law in force since 15 April 2025, sets out the fixed shares at Articles 205 to 233: a half, a third, a quarter, an eighth, a sixth, allocated to named relatives in named configurations. Article 1(1) applies it to UAE citizens where one party to the relationship is Muslim. Article 1(3) applies it to non-citizens unless one of them insists on their own national law.
The civil track is newer and shorter. Federal Decree-Law 41/2022 on Civil Personal Status, in force 1 February 2023, applies to non-Muslims: non-Muslim UAE citizens, and non-Muslim foreigners residing in the country, unless they adhere to the law of their home country. Its default runs to one sentence. Half the estate to the husband or wife, the other half divided equally among the children, "with no differentiation between male and female" (Article 11(2)). Abu Dhabi runs a parallel emirate-level version, Law 14/2021, whose Article 11 says materially the same thing.
So the shape of it is this. Two default cascades, each keyed to the personal status regime that governs the deceased, and a claimant's share is whatever their cascade gives them once they are proved to be who they say they are. Everything after this is detail.
Daniel's estate sits on the civil track by default.
An omission is a document problem before it is a dispute
Almost every UAE asset route waits on the same court instrument, with narrow exceptions for final wages under a written employer nomination and scheme balances paid on a beneficiary form. Banks release balances against a court order identifying who is entitled, per their published terms. The Dubai Land Department transfers property to heirs against a Legal Notification of Inheritance plus an official court letter. The Abu Dhabi Judicial Department notarises a notice of succession listing the legal heirs. The emirates name that document differently; this guide calls it the Declaration of Heirs.
Article 1244 of the Civil Transactions Law (Federal Decree-Law 25/2025, in force 1 June 2026): the competent court, at the request of one of the heirs or any interested party, issues a certificate establishing the identity of the heirs and the share of each. Creditors count among interested parties, so the file can open without the family. In Dubai the venue is the Probate Court, created by Decree 25/2023, and the estate file opens on a concerned party's request.
What the court reads is paper. The death certificate first, then proof of relationship: marriage certificates, birth certificates. Where a document was issued abroad it enters the file translated into Arabic and attested along the full chain, meaning the foreign ministry of the issuing country, then the UAE embassy there, then the UAE Ministry of Foreign Affairs.
The court certifies from the file in front of it. A child whose parentage evidence never reached that file can be left off the initial application, or can surface later as a dispute over the list. Article 1228 of the same law is specific: before the certificate exists, an heir may not dispose of any estate asset, collect debts owed to the estate, or set off debts against it. Correcting the list afterwards means reopening what banks, registries and buyers have already relied on.
For Daniel the whole exposure fits in one line. Theo exists in a Lisbon register and in a bank transfer every September, and in nothing a Dubai court will ever see.
The Dubai Land Department asks for Emirates ID copies of all heirs and passports for non-resident heirs, and charges AED 1,000 per property for the inheritance transfer (DLD published fee schedule, checked 25 July 2026).
The five people who can surface, and what each one holds
Each category below holds a position defined by a single document.
The acknowledged child from another relationship
On the civil track, Article 14(1) of Federal Decree-Law 41/2022 establishes parentage "by marriage or by the acknowledgment of the father and mother", with the birth certificate issued accordingly. Acknowledgment stands as its own route, beside marriage rather than behind it. Article 11(2) then distributes half the estate among "the children ... with no differentiation between male and female", and nothing in that wording limits "the children" to the current marriage.
Here is the honest state of it. No provision says in so many words that an acknowledged child from an earlier relationship takes an Article 11(2) share. The wording is general and untested on exactly this case, so a lawyer has to read it against your family. What is not in doubt either way is the gate: established parentage on paper is what puts the child into the estate conversation at all.
On the Sharia track, Article 207 of Federal Decree-Law 41/2024 defines the inheriting descendant as the son and his line through males, and the daughter. The widow's fixed share drops from a quarter to an eighth where the husband leaves an inheriting descendant (Article 212(1)). Put those articles side by side and a child of a recognised earlier marriage counts as the husband's descendant and moves that fraction. Confirming that for a real family is counsel's job.
There is no clear published answer on the Sharia track for a child born outside marriage whose parentage was established later. That one goes to a lawyer with the file open.
Daniel's version of this is administrative rather than legal. The acknowledgment already exists, in Portugal, in Portuguese, and has never been translated, attested or shown to anyone here.
The child whose relationship was never documented
Without acknowledgment, marriage or a birth certificate naming the deceased, this child starts with nothing on file. The route is judicial. Article 14(2) of Federal Decree-Law 41/2022 lets the court order DNA testing, and it issues a parentage order only after verifying two conditions, quoted from the article: that the child is "of an unknown parentage", and that "the age difference is likely to establish the child's relationship with the claiming person".
That claim arrives as a court case rather than as a filing, and the estate waits while it runs.
The spouse from a ceremony no state recorded
The intestate categories are closed lists. On the civil track: husband or wife, children, parents, siblings (Article 11(2)). On the Sharia track: the fixed-share heirs of Article 210. A partner whose wedding exists in photographs and family memory, but in no state register, falls into none of those categories. The UAE has no concept of common-law marriage.
The document that changes the position is a marriage certificate issued or recognised by a state, translated and attested. It makes the survivor a spouse, and the cascade rearranges around them. Without one, the survivor's share is zero on every track.
The second wife where the marriage is recognised
Where the estate runs on the Sharia track and a second marriage is recognised, the answer is arithmetic. Article 212(2) of Federal Decree-Law 41/2024: "When wives are multiple, they divide the share of one wife." The quarter or the eighth is a single block, and co-widows split it between them rather than each taking one.
The UAE civil marriage regime is one man and one woman, so the co-widow question belongs to the Sharia track. The second wife's claim stands on her attested marriage certificate. Absent recognition by any state, she stands in the previous category instead.
The dependant with no heir status at all
Who holds no heir status depends on the track, and the gap is widest for a parent.
On the civil track, parents and siblings sit in Article 11(2) only as fallback tiers. Where a spouse and children survive, those tiers never open. On the Sharia track a parent is an heir outright. The father and mother take fixed shares even where children survive, the father one-sixth where there is a male inheriting descendant (Articles 210 and 213 of Federal Decree-Law 41/2024).
Outside every heir class on every track sit the unmarried partner and the domestic worker. Some countries let a dependant who was never an heir claim provision from an estate anyway. No such route is published in UAE law, and whether anything exists for a particular household is a question for counsel.
Two positions a dependant can still hold. Creditor: unpaid wages are estate debts, settled before anyone inherits, and a domestic worker's dues carry statutory priority over the heirs, behind only public treasury amounts and legal alimony (Federal Decree-Law 9/2022, Article 28(6)). Beneficiary: a registered non-Muslim will may name "anybody he wants" (Article 11(1)), and on the Sharia track a bequest outside the heir list is available within one third of the net estate (Articles 173 and 181).
One further category sits inside the bloodline. On the Sharia track, grandchildren whose parent died before the deceased hold a mandatory entitlement, Al-Wasiya Al-Wajibah, within that same one third (Article 179 of Federal Decree-Law 41/2024).
The Heir Audit
The framework is The Heir Audit: the five categories above crossed with the two tracks, each cell naming the standing that category has and the document that would establish or defeat it. Two variables, because those are the two that decide the answer.
Ten minutes with a pen. For each row, name every living person who fits, then check whether the document in the last column exists and whether it is translated and attested. A name with no document next to it is the exposure.
| Claimant category | Standing on the Sharia track (FDL 41/2024) | Standing on the civil track (FDL 41/2022) | The document that establishes or defeats the claim |
|---|---|---|---|
| Acknowledged child from another relationship | A child of a recognised earlier marriage is treated as a descendant, reading Articles 207 and 212 together. For a child acknowledged outside marriage, counsel | Article 11(2) gives "the children" half, with no marriage qualifier. A lawyer reads that wording against the actual parentage papers | Birth certificate or acknowledgment record naming the deceased, translated and attested |
| Child, parentage never documented | No settled position to work from; counsel | No route into Article 11(2) without parentage; the Article 14(2) DNA order requires two verified conditions | A court parentage order; without proceedings, nothing |
| Spouse from a ceremony registered nowhere | Outside the Article 210 fixed-share list | Outside the closed Article 11(2) categories | A state-issued or state-recognised marriage certificate would establish it; its absence defeats it |
| Second wife, marriage recognised | Co-widows divide the single wife's share, Article 212(2) | Civil marriage is one man and one woman, so the question sits on the Sharia track | Her marriage certificate, attested along the full chain |
| Grandchild of a predeceased child | Mandatory will within the one-third limit, Article 179 | Not in the closed Article 11(2) list; a registered will is the route | The predeceased parent's death certificate plus lineage documents |
| Dependant with no heir status (partner, relative, worker) | No share; bequest possible within 1/3; unpaid wages rank as estate debts with priority | No share; a registered will may leave them anything under Article 11(1) | Employment contract or debt evidence for the creditor position; a registered will for the bequest |
Daniel's audit has one row with a name in it and no document, and it is the first row. Keep the finished table with the will and the other estate papers.
What a surfaced claimant does to the family already in the room
Distribution waits. The certificate of heirs is the gate on every asset, the Article 1228 bar sits over the estate until it exists, and banks hold funds until a court order names who is entitled (the freeze mechanics in why the accounts freeze, and what a family can still use). A claimant contesting the list extends that wait. Under Article 5(2) of Federal Decree-Law 41/2024 the Inheritance Judge rules on the list of heirs and hears the disputes deriving from the estate, so a parentage or marriage claim lands inside the estate file, ahead of distribution.
Obligations do not wait with it. Loan instalments keep falling due, a tenancy keeps running, school fees keep accruing, and the estate settles its debts before any heir receives anything, whoever ends up on the final list. Anna's mortgage does not pause because a claim has been filed in Lisbon. The visible family carries the household out of whatever sits outside the estate.
The governing law itself can also move. Article 11(3) of Federal Decree-Law 41/2022: absent a registered will, any of the foreigner's heirs may request the application of the law applicable to the estate under the Civil Code. A claimant who establishes heir status acquires that lever along with the share: one newly recognised heir can ask for a different national law for the whole estate. The country-by-country differences are mapped in UAE inheritance by nationality. A registered will closes that door.
Where the heir list sits inside the wider sequence of certificates, freezes and transfers is laid out in the full week-by-week timeline.
What a testator with a complicated history can do in advance
The estate will meet the family as the documents describe it. What a testator controls is the record: disclosing the full family history, obtaining or correcting the lawful documents, and directing a will.
- Write the real list. Every child from every relationship, every marriage with dates and countries, every dependant. On paper, once, completely. A will prepared through the SmartWills process and reviewed by UAE-licensed partner lawyers starts from this list.
- Collect the certificates while alive. Birth certificates, acknowledgment records, marriage certificates, with Arabic translations and the attestation chain (issuing country's foreign ministry, UAE embassy, UAE Ministry of Foreign Affairs). After death the same documents may need retrieval, translation and attestation across more than one country, by people who have never seen them.
- Register a will. A non-Muslim may dispose of UAE assets in favour of anyone (Article 11(1)), and the registered will blocks the Article 11(3) election of a different law. It also names the proposed executor, who administers the estate once the court confirms the appointment (Article 1221 of the Civil Transactions Law) or, for a DIFC will, once the Registry issues the grant of probate. See which registry route fits which profile.
- A Muslim testator plans inside different walls. Start with the registers. The most defensible published position is that Dubai Courts and ADJD accept wills from Muslims provided the will complies with Sharia, while the DIFC registers non-Muslim wills only. Then the bequest. The one-third reaches people outside the heir list, and a bequest to an heir works differently: it takes effect either with the approval of the other mature heirs, and then only against the shares of those who consented, or where the court acknowledges a likely interest, in which case it runs despite their objection (Article 184). Then choice of law: Article 1(3) of Federal Decree-Law 41/2024 lets a non-UAE citizen insist on their national law. Which combination serves a family is counsel work.
- Use the employer nomination. Article 15(2) of Federal Decree-Law 33/2021 lets a worker specify in writing which family member receives final wages and gratuity on death. The nomination is one written line.
- Re-run the Heir Audit at every family event. An acknowledgment, a marriage, a birth, a divorce: each can leave the will describing a family that has since changed shape. The five-question drawer audit covers documents that have drifted from the facts.
The instinct to keep an old chapter off the paperwork is understandable: naming a child from another relationship can feel like creating the claim. Where the law gives the claim, it already exists. The paperwork decides only whether the estate meets it as a documented entry on the heir list, or as litigation with every asset waiting on the outcome.

Frequently asked questions
Can a child from another relationship claim inheritance in Dubai?
Yes, once their parentage to the deceased is legally established. On the civil track, Article 11(2) of Federal Decree-Law 41/2022 distributes half the estate among "the children", wording that carries no marriage qualifier. On the Sharia track, a son takes as an agnatic residuary heir and a daughter takes a fixed share or joins the sons in the residue. The gate in practice is documentation: a birth certificate or a parental acknowledgment, translated into Arabic and attested.
Does a second wife inherit under UAE law?
Where the marriage is recognised and the estate runs on the Sharia track, the statute answers directly. Article 212 of Federal Decree-Law 41/2024 gives the wife a quarter of the estate where there is no inheriting descendant and an eighth where there is one, and multiple wives divide that single share between them. Her claim stands on an attested marriage certificate.
Can an unmarried partner claim part of a UAE estate?
By default, nothing. The intestate categories are closed: spouse, children, parents and siblings on the civil track, the fixed-share list on the Sharia track, and a partner appears in neither. A registered will changes the picture for a non-Muslim testator, since Article 11(1) of Federal Decree-Law 41/2022 permits leaving UAE assets to anybody the testator wants. Absent a will, a partner's only possible position is creditor, for a provable debt.
Who applies for the Declaration of Heirs, and with what evidence?
Under Article 1244 of the Civil Transactions Law (Federal Decree-Law 25/2025, in force 1 June 2026), any heir or any interested party, creditors included, may ask the competent court for the certificate identifying the heirs and their shares. In Dubai the estate file opens at the Probate Court on a concerned party's request. In Abu Dhabi the ADJD notarises its notice of succession. The application rests on the death certificate plus the relationship documents, translated into Arabic and attested through the full chain where they were issued abroad.
Can a registered will stop a surprise heir claim?
It narrows the field considerably without sealing it. A registered non-Muslim will directs UAE assets to named beneficiaries and blocks the Article 11(3) request to apply a different national law, which removes the surfaced heir's largest lever. What it leaves untouched is parentage. A person who establishes a legal relationship to the deceased can still bring that to the court, and on a Sharia-track estate the fixed shares operate regardless. The strongest position pairs the will with a complete, attested document file.
