Mainland, Free Zone, DIFC, or ADGM: What Each Commits You To

Mainland companies are formed under UAE federal commercial law and are licensed to operate across the wider UAE market without the geographic restrictions that some free zone licences carry.

Free zone companies are formed under the rules of whichever specific free zone they’re licensed in — there are many free zones across the UAE, each with its own licensing authority, and (outside DIFC and ADGM) generally operating within the federal legal framework rather than a separate one.

DIFC companies are formed under DIFC’s own companies law, within DIFC’s broader legal system. ADGM companies are formed under ADGM’s own framework, which — distinctively — applies English law directly in key respects rather than a UAE-drafted statute modelled on it.

These aren’t four flavours of the same underlying company law — they’re four different starting points, and the choice between them shapes what the company can do, and what happens to it in a dispute or insolvency, for as long as it exists.

Mainland companies operate under the federal Commercial Companies Law framework, which — as described further below — was significantly updated by Federal Decree-Law No. 20 of 2025, effective from 15 October 2025.

Mainland formation generally gives a company the broadest UAE market access of the options covered here, without the sector or geographic limitations that can attach to some free zone licences — a relevant factor for a business whose model depends on operating across the wider domestic market rather than within a specific zone.

Free zone companies (outside DIFC and ADGM) are licensed and governed by the rules of their specific free zone authority, generally operating within the broader federal legal framework for matters the free zone’s own rules don’t specifically address.

Free zones vary considerably by sector focus, cost structure, and specific licensing rules, but as a group they sit apart from DIFC and ADGM in one important respect: they don’t generally carry a separate, self-contained common-law legal system the way DIFC and ADGM do.

DIFC companies are formed under DIFC’s own companies law, part of DIFC’s broader English-language, common-law legal system, with disputes ultimately falling to the DIFC Courts rather than the onshore court system.

DIFC is generally associated with financial services and related professional activity, reflecting its origins and regulatory focus, though its company law framework itself is of general relevance to how a DIFC entity is structured and governed.

ADGM is distinctive among the four in that it applies English law directly in significant respects, rather than a UAE-drafted statute modelled on English principles. For partnerships specifically, ADGM applies the English Partnership Act 1890 and the Limited Partnerships Act 1907 directly.

This direct application of established English statutes gives ADGM entities — and the lawyers and investors dealing with them — a body of English case law and settled interpretation to draw on that a newly drafted, UAE-specific statute wouldn’t carry in the same way.

Federal Decree-Law No. 20 of 2025, effective from 15 October 2025, amended the Commercial Companies Law to allow multiple LLC share classes — a meaningful change for onshore companies that previously had less flexibility to structure differentiated shareholder rights within an LLC.

The same amendment expressly allows an onshore LLC’s memorandum of association (or a private joint stock company’s articles) to include drag-along and tag-along clauses — clauses that let one or more partners require the others to sell to a third party on conditions agreed in advance (drag) or let a partner join a sale on the same terms agreed with the buyer (tag) — so these now rest on the statute where the constitutional documents include them, rather than having to be built entirely through private contractual arrangements.

The same Federal Decree-Law No. 20 of 2025 also introduced intra-UAE re-domiciliation, allowing a company to move between UAE jurisdictions with continuity of legal personality — meaning the company doesn’t have to be dissolved and re-formed from scratch to relocate its jurisdiction within the UAE.

This is a significant practical change for a company that formed in one jurisdiction and later finds a different one better suited to its stage or activities — though the specific mechanics and eligibility for a given re-domiciliation are worth confirming directly rather than assuming it’s available in every direction between every pair of jurisdictions.

A significant, often underappreciated difference between onshore (mainland and standard free zone) and ADGM structures is in the security and insolvency toolkit available. Onshore, there is no floating charge, no scheme of arrangement, no security trustee mechanism, and no contractual enforcement of share pledges in the way common-law systems provide for.

This matters directly for lenders and investors structuring security over a UAE company’s assets or shares — the tools that a common-law-trained lawyer or lender might reflexively reach for simply aren’t available in the same form onshore, and security arrangements need to be built around what onshore law actually permits rather than imported wholesale from a common-law playbook.

ADGM alone, among the four, offers Deeds of Company Arrangement (DOCAs) and cross-class cram-down — restructuring tools that let a company reach a binding arrangement with creditors, in some cases even binding a dissenting class of creditors, as part of an insolvency or restructuring process.

This gives ADGM-structured entities and their creditors a materially more developed restructuring toolkit than is available onshore or, for these specific mechanisms, in DIFC — a genuine factor for anyone structuring a transaction where restructuring flexibility down the line is a real consideration.

There is no fund passport between mainland, DIFC, and ADGM — a fund or fund manager structured in one of these jurisdictions doesn’t automatically get recognised or permitted to operate in another simply by virtue of being properly licensed where it’s based.

For fund structuring specifically, this means the choice of jurisdiction is not just about where to be based but about where the fund actually needs to be recognised to operate — a question worth working through carefully with a lawyer rather than assuming licensing in one jurisdiction carries over.

Economic Substance Regulations (ESR), which previously required certain UAE entities to demonstrate adequate substance for specific categories of activity, no longer carry notification and reporting obligations for financial years ending after 31 December 2022, under Cabinet Decision No. 98 of 2024 amending Cabinet Decision No. 57 of 2020. The trigger is the financial year-end, not the calendar date, and obligations for earlier financial years survive.

For most companies today, ESR is a legacy remediation matter — relevant to closing out obligations and filings for periods up to that cut-off — rather than a live, ongoing compliance requirement. It shouldn’t be treated as a current operational burden in the way it was before the 2022 cut-off, though any unresolved historic ESR position should still be properly closed out.

Mainland formation tends to suit businesses whose model depends on broad UAE market access without free zone restrictions. Standard free zones suit businesses that fit a specific zone’s sector focus and don’t need onshore market access in the same way.

DIFC and ADGM tend to suit businesses — particularly in financial services, funds, and related professional activity — that benefit from a common-law legal system, English-language courts, and, in ADGM’s case specifically, a more developed security and insolvency toolkit.

None of these is a universally “better” choice — the right one depends on the business’s actual activities, its financing and investor structure, and how much it values the specific legal tools (share class flexibility, restructuring mechanisms, market access) each jurisdiction offers.

That moving a company between UAE jurisdictions always meant winding it up and starting again — since Federal Decree-Law No. 20 of 2025, intra-UAE re-domiciliation with continuity of legal personality is now available, though specific eligibility should be confirmed.

That onshore companies have the same security toolkit as common-law systems — they don’t; there’s no floating charge, scheme of arrangement, security trustee, or contractual share-pledge enforcement onshore in the way common-law practitioners might expect.

That DIFC and ADGM offer the same restructuring tools — they don’t; DOCAs and cross-class cram-down are specifically ADGM mechanisms as described here.

That Economic Substance Regulations are still a live, ongoing compliance requirement — notification and reporting obligations were lifted for financial years ending after 31 December 2022 under Cabinet Decision No. 98 of 2024, making it a legacy remediation matter rather than a current burden. It is not a clean slate, though: earlier financial years still count, and regulator information requests still have to be answered.

That a fund licensed in one UAE jurisdiction can automatically operate in another — there is no fund passport between mainland, DIFC, and ADGM.
