It’s a major shift in how adulthood is defined in UAE law, especially in civil and financial matters.

What changed

Until now, adulthood in the UAE was based on the Islamic (Hijri) lunar calendar and set at 21 lunar years. Because lunar years are shorter than Gregorian years, this effectively meant legal adulthood started at about 20 years and 4 months in the standard calendar most people use.

The new rule switches to the Gregorian calendar and lowers the threshold to 18 years.

This also aligns the UAE with how adulthood is defined in most other countries and removes confusion for expatriates, since official documents like passports and contracts use the Gregorian system.

What 18-year-olds can now do

From 1 June 2026, anyone aged 18 or older is legally considered an adult in civil matters, unless a court rules otherwise.

This means they can:

  • Sign contracts without parental or guardian approval
  • Buy, sell, or manage personal property and assets
  • Open or run a business
  • Take legal action or be sued in their own name
  • Make independent financial decisions

Some of these rights already existed in practice (like working full-time, driving, or getting married), but this update extends full legal capacity to civil and financial matters.

Lower age access for younger individuals

The law also adjusts rules for minors in specific cases.

Individuals as young as 15 (Gregorian age) can now apply to a court for permission to manage their own financial assets, compared to the previous higher threshold.

This supports early financial independence in controlled cases, especially for young entrepreneurs or those handling inherited assets.

What this means for families and expats

For families living in the UAE, the key change is timing and responsibility.

Once a child turns 18, they can legally act on their own in most financial and civil situations. This includes signing rental agreements, managing inheritance, or entering business arrangements without parental involvement.

Because of this shift, families may need to review wills, inheritance plans, and any structures where young adults are included in ownership or decision-making.

Are there protections?

Yes. Courts still have the power to intervene if someone is unable to manage their affairs properly or is at risk of exploitation.

They can also appoint a judicial assistant to help individuals who need support in handling legal or financial responsibilities.
