DIFC or ADGM: where should your Gulf will sit, and why it matters

For most non-Muslim British expats in the UAE, the short version is this: DIFC in Dubai is the stronger, court-based route with its own probate, and it costs more; ADGM in Abu Dhabi is leaner and cheaper to register, but probate happens elsewhere. Which one fits you depends mainly on where your assets and family are, not on which is "best" in the abstract. And whichever you choose, it deals with your UAE estate, not your UK one.

Both sit in common-law free zones and both are built for non-Muslims, so people assume they're interchangeable. They aren't. The difference is in what happens after death, and that's the part worth understanding before you choose.

What the two routes actually are

DIFC runs a court-linked wills registry. You register your will with the DIFC Courts, and when you die your executor goes back to those same courts for a grant of probate, and for guardianship orders where children are involved. Registration is fully digital and can be done by video call from anywhere, with no need to be a UAE resident or to travel. You must be non-Muslim (and never have been), at least 18, and own UAE assets or have minor children living in Dubai or Ras Al Khaimah.

There are six will types, from a Full Will covering all your UAE assets to narrower ones for property, financial accounts, company shares, guardianship or digital assets. Registration fees are court fees on top of any drafting cost: a single Full Will is AED 10,000, mirror Full Wills AED 15,000, with the narrower wills from AED 5,000. One quirk matters for planning: DIFC doesn't accept codicils, so any change means a new will.

ADGM works differently. It's a notarisation service run with the Abu Dhabi Judicial Department, not a separate probate court. You're eligible as a non-Muslim aged 21 or over who owns UAE assets. The will must be bilingual, in Arabic and English, certified by a UAE-licensed translator, and it can include a clause choosing UAE law and disapplying sharia. The registration fees are much lower, AED 950 to the ADJD plus USD 155 to the ADGM Courts. The catch is at the other end: ADGM doesn't issue grants of probate. When you die, probate is handled through the ADJD and the authorities where your assets actually sit.

That's the real distinction your family feels later. DIFC is registry plus probate in one specialist court. ADGM is notarisation here, probate elsewhere.

The cross-emirate question

On paper, both routes can reach assets across the UAE. DIFC extended its coverage to all emirates back in 2019, and a 2025 Dubai law strengthened the enforcement of DIFC-registered wills outside the DIFC. ADGM can notarise a will covering assets elsewhere in the UAE too.

In practice, coverage is not the same as one-stop administration. Wherever the will is registered, transferring an asset still runs through the authority that controls it, sometimes with Arabic translation and local execution steps. So the honest question isn't "where is my will valid", it's "after I die, who will my family have to deal with, in which language, and in how many stages". A will registered with the same court that issues the probate keeps more of that in one place. That's the main reason DIFC tends to feel cleaner for Dubai-centred estates and ADGM more natural for Abu Dhabi-centred ones.

One thing to clear up, since it puts people off unnecessarily: sharia does not automatically apply to non-Muslims any more. A 2022 federal law gives non-Muslims a civil framework with full freedom to leave their UAE assets as they choose, and a civil default (half to the spouse, half to the children) where there's no will. The wider conflict-of-laws rules were updated again from June 2026, so current drafting should be done by someone working from the live wording rather than an old template.

Which route fits which family

The useful question is what each is built to do.

A Dubai-based family with local assets and minor children usually fits DIFC best. It can cover the UAE assets and guardianship in one instrument, and the DIFC Courts issue both the probate and the guardianship orders. If the children live in Dubai or Ras Al Khaimah, the guardianship fit is especially strong.

An Abu Dhabi resident who wants a proportionate, lower-cost option, with an estate that sits mainly in Abu Dhabi, often fits ADGM well. The registration fees are far lower and the process is integrated with the Abu Dhabi courts anyway. Just budget for the translation cost, and remember probate runs through the ADJD rather than ADGM.

Someone with assets spread across several emirates is usually safer with a DIFC Full Will if the budget allows, because it gives the family one specialist court to anchor the administration, rather than notarising in one place and proving the will somewhere else.

A guardianship-driven case again tends to point to DIFC, which has a dedicated guardianship route and issues its own orders. ADGM can handle guardians too, through the ADJD form, but DIFC usually makes the simpler story for parents.

A cost-sensitive single person with modest UAE assets and no children can reasonably choose ADGM if the estate is Abu Dhabi-centred. If it's Dubai-centred, the lower sticker price doesn't automatically win, because the extra administration layer can mean more work for the executor later.

Neither one settles your UK estate

This is the point people most often get wrong. A Gulf will, DIFC or ADGM, is built for UAE assets. It does not deal with UK probate and it does not switch off UK inheritance tax.

Since 6 April 2025, whether your worldwide assets fall within UK inheritance tax turns on long-term residence: broadly, if you've been UK resident for at least 10 of the last 20 tax years, your worldwide estate can be in scope, with a tail of years after you leave. Anything physically in the UK stays taxable regardless of where you live. The familiar figures still apply, a £325,000 nil-rate band and a residence nil-rate band of up to £175,000, with 40 per cent above the threshold and a taper once the estate passes £2 million. The UK-UAE treaty doesn't rescue you here: it covers income and capital gains, not inheritance tax.

Both DIFC and ADGM wills can mention assets outside the UAE, but that isn't a substitute for an English will handling UK administration and UK tax. The right answer for British expats is almost always coordinated wills, a Gulf will for the Gulf assets and a UK will for the UK ones, drafted so that neither accidentally revokes the other.

Where this leaves you

If your assets and family are mainly in Dubai, especially with children, DIFC is usually the clearer choice because the will sits with the same court that issues the probate and guardianship orders. If your estate is mainly in Abu Dhabi and cost matters, ADGM is often the proportionate option, as long as you're comfortable with the bilingual drafting and the fact that probate runs through the ADJD. And in either case, keep your UK estate on its own coordinated UK will.

That UK will is what Expat Legacy is built to provide: a clear, valid UK will for British expats, in plain English, designed to sit alongside your DIFC or ADGM will rather than clash with it.
