Turning 18 in the UAE now carries greater legal significance than before.
Under Federal Decree-Law No. (25) of 2025 promulgating the Civil Transactions Law, which came into effect on 1 June 2026, the general age of civil majority was reduced from 21 lunar years to 18 Gregorian years.
This change means that young adults who meet the legal capacity requirements can generally manage their own civil and financial affairs without requiring parental or guardian approval.
They may be able to enter contracts, manage property, undertake business activities and exercise their civil rights independently.
However, greater legal independence also brings greater responsibility.
An 18-year-old who signs a contract without understanding its terms may still be legally bound by it. A financial commitment entered into today could have consequences for years.
So, what exactly changes at 18, and what should young adults and their families understand?
What Has Changed About the Legal Age of Adulthood in the UAE?
Previously, the UAE’s general civil law framework recognised the age of majority at 21 lunar years.
The new Civil Transactions Law establishes 18 Gregorian years as the age of majority.
Article 84 provides that a person who has reached the age of majority, enjoys full mental capacity and is not subject to a legal restriction on capacity has full capacity to exercise civil rights.
The reform creates a clearer threshold for civil transactions and financial independence.
It also aligns the general age of civil majority more closely with other aspects of the UAE legal framework.
However, the change does not mean that every activity becomes legally available at 18. Separate legislation may establish different requirements for particular activities.
What Does Reaching Legal Adulthood Mean?
Legal adulthood concerns a person’s capacity to exercise rights and undertake legal obligations independently.
In practical terms, an adult with full legal capacity can generally make decisions about their civil and financial affairs without another person automatically acting on their behalf.
These decisions may involve:
- Signing agreements
- Managing money
- Owning assets
- Entering commercial relationships
- Taking responsibility for contractual obligations
- Participating in civil legal proceedings
The key distinction is that the person may now have the legal authority to make these decisions independently.
That authority does not guarantee that every decision will be financially beneficial or legally risk-free.
Can an 18-Year-Old Sign Contracts in the UAE?
Generally, yes.
An individual who has reached 18 and satisfies the relevant legal capacity requirements can ordinarily enter civil contracts independently.
Examples may include:
- Residential tenancy agreements
- Service contracts
- Education-related agreements
- Commercial agreements
- Certain financing arrangements
- Employment contracts, subject to applicable labour legislation
However, signing a contract creates obligations.
Consider an 18-year-old who signs a residential tenancy agreement.
The tenant may become responsible for rent, contractual notice requirements and other lawful obligations under the agreement.
Similarly, signing a service agreement may create an obligation to pay fees or comply with termination conditions.
Reaching legal adulthood means gaining the capacity to enter agreements—not the right to disregard them later.
Young adults should therefore review contracts carefully before signing.
Can Young Adults Own Property and Manage Their Assets?
The reform also affects how young adults manage property and financial assets.
A person who has reached the age of majority and has full legal capacity can generally exercise greater independence over assets that legally belong to them.
Depending on the circumstances, this may involve:
- Managing bank accounts
- Controlling personal savings
- Dealing with investments
- Managing inherited assets
- Entering property-related transactions
- Authorising certain financial arrangements
However, ownership and the ability to dispose of an asset are not always identical.
Property registration requirements, existing ownership restrictions, trust or guardianship arrangements, and other applicable legal conditions may still need to be considered.
For example, owning property in Dubai remains subject to the relevant property ownership and registration framework.
An individual’s age does not override those requirements.
Can an 18-Year-Old Start or Own a Business?
The reduction in the age of majority is particularly relevant to young entrepreneurs.
An individual who has reached 18 may generally have the civil legal capacity to enter business-related agreements and participate in commercial activities.
This may include:
- Signing commercial contracts
- Entering partnership arrangements
- Establishing certain business structures
- Managing business-related assets
- Undertaking contractual obligations
However, company formation and commercial licensing are governed by additional requirements.
The relevant licensing authority, business activity, legal structure and sector-specific regulations must still be considered.
For example, certain regulated professional activities may require qualifications, experience or separate approvals.
Can Someone Under 18 Manage Their Assets?
The new law also introduces an important provision for younger individuals.
The UAE Government has confirmed that the age at which a minor may seek judicial authorisation to manage their assets has been reduced to 15 Gregorian years.
This does not mean that every 15-year-old automatically gains full legal capacity.
Instead, it creates a route for eligible minors to seek court authorisation within the applicable legal framework.
The reform may support young people seeking to participate in economic activities under appropriate judicial supervision.
What Financial Responsibilities Begin at 18?
Financial independence brings legal consequences.
A young adult entering a financial agreement should understand that the agreement may create enforceable obligations.
For example, a person may become responsible for:
- Contractual payments
- Outstanding invoices
- Rent
- Agreed service fees
- Financial commitments
- Damages arising from certain contractual breaches
Financial institutions may still apply eligibility, affordability and product-specific requirements.
Being legally capable of entering a contract does not mean a bank must approve a credit card, loan or financing application.
Before taking on financial commitments, young adults should understand the repayment terms, charges and consequences of default.
Are Young Adults Responsible for Their Own Legal Decisions?
In civil matters, the change means that eligible individuals aged 18 or older generally have the capacity to exercise their rights and undertake obligations independently.
This can affect contractual disputes, financial claims and other civil proceedings.
For example, if an adult enters a valid contract and fails to perform an obligation, the other party may potentially pursue legal remedies.
Similarly, a young adult whose contractual rights have been breached may have the capacity to pursue an appropriate legal claim.
However, legal capacity does not remove the need to establish the ordinary requirements of a claim.
Liability still depends on the applicable law and the circumstances.
Does Turning 18 Change Criminal Responsibility?
This distinction is particularly important.
The reform under the Civil Transactions Law concerns the general age of civil majority.
Criminal responsibility is governed by separate legislation.
The UAE’s criminal and juvenile justice frameworks contain their own rules concerning age, responsibility and procedures.
It would therefore be incorrect to assume that a person becomes subject to criminal law only upon turning 18.
Likewise, reducing the civil age of majority does not automatically alter every criminal law provision.
The applicable criminal legislation must be examined separately.
What Happens to Parental Authority and Guardianship?
The change may affect arrangements through which parents or guardians previously managed the civil and financial affairs of young people.
Once an individual reaches the age of majority and satisfies the requirements for full legal capacity, the ordinary justification for managing that person’s affairs solely because of minority may cease to apply.
However, existing court orders, particular guardianship arrangements and other legally recognised restrictions may require separate consideration.
The law also provides mechanisms for individuals who require judicial assistance or whose legal capacity is restricted in accordance with applicable provisions.
Families should therefore avoid assuming that every existing arrangement automatically ends without reviewing its legal basis.
Important Exceptions and Special Age Requirements
The new age of majority should not be interpreted as a universal age threshold for every legal activity.
Different laws may regulate:
- Marriage
- Driving
- Employment
- Banking products
- Regulated professions
- Commercial licensing
- Certain financial transactions
- Criminal responsibility
Some activities may be permitted before 18, while others may involve additional conditions after 18.
The correct approach is to distinguish general civil capacity from the specific eligibility requirements governing a particular activity.
What Should Parents and Young Adults Prepare For?
The reform creates practical considerations for families.
Review Existing Financial Arrangements
Where parents have been managing assets or accounts for a young person, they should establish whether changes are required under the applicable rules.
Understand Contractual Obligations
Young adults should read agreements carefully before signing.
Important clauses include:
- Payment obligations
- Contract duration
- Termination conditions
- Penalties or charges
- Liability provisions
- Dispute resolution
Review Property and Inheritance Arrangements
Families should consider whether existing documents, ownership structures or guardianship arrangements require review.
Seek Advice Before Major Transactions
Property purchases, business partnerships, substantial financial commitments and complex contracts may justify professional legal review.
Why Legal Advice Matters
The reduction in the age of majority is a significant change to the UAE’s civil legal framework.
However, the practical consequences will depend on the transaction, the individual’s legal capacity and any applicable special legislation.
Legal advice may be particularly important when dealing with:
- Property ownership
- Business formation
- Commercial agreements
- Financial disputes
- Guardianship arrangements
- Inheritance matters
- Contractual liability

Conclusion
The UAE’s decision to establish 18 Gregorian years as the general age of civil majority represents an important change for young adults.
Under the Civil Transactions Law, eligible individuals can exercise greater independence in managing their contracts, property, financial affairs and other civil rights.
But independence also means accountability.
An 18-year-old entering a legally binding agreement should understand the obligations involved, the potential consequences of non-performance and any separate legal requirements that apply.
For parents and young adults, the most important step is understanding which decisions can now be made independently and which remain subject to additional legal conditions.
Turning 18 may give you greater control over your legal and financial affairs. Knowing how to exercise that control responsibly is equally important.
