What Is Legal Capacity Under Saudi Law?
The Saudi Civil Transactions Law divides individuals into categories based on their ability to perform legally binding acts. This is known as legal capacity or competency, and it determines whether a person can independently sign contracts, own property, or represent themselves in legal matters.
Full Legal Competency
Under Article 12, a fully competent person is someone who meets all three of the following criteria:
- Has reached the age of majority (18 years by the Hijri calendar)
- Has full mental capacity
- Has not been interdicted (legally restricted from managing their own affairs)
For expats, it is important to note that the age of majority is calculated according to the Hijri calendar, which means it may differ slightly from your home country's Gregorian-based calculation. If you are dealing with a young adult who is close to 18, always verify their Hijri age before entering into a significant contract with them.
Partial Incompetency: Who Is Affected?
Article 14 identifies three categories of partially incompetent persons:
- Minors who have reached the age of discernment but are under 18 (Hijri)
- Persons with diminished mental capacity who do not meet the threshold of full idiocy
- Persons interdicted for being a spendthrift or imprudent with finances
Partially incompetent individuals can perform some legal acts independently but require supervision or guardian approval for others.
Full Incompetency
Article 13 defines a fully incompetent person as someone who is non-discerning due to:
- Young age — any child under seven years old is automatically presumed non-discerning
- Idiocy — a severe lack of mental capacity
Contracts or transactions entered into by a fully incompetent person are generally void under Saudi law.
Guardianship and Trusteeship
If you are an expat parent or legal guardian of a minor or incompetent person in Saudi Arabia, Article 15 requires that such individuals be subject to formal guardianship or trusteeship provisions. This means:
- A legal guardian must represent the incompetent person in all significant transactions
- The domicile of an incompetent person is legally the same as that of their guardian (Article 10)
- A partially incompetent person may have their own domicile only for acts they are legally permitted to perform independently
Key Practical Advice for Expats
1. Verify capacity before signing contracts Always confirm the other party's legal capacity before entering a major agreement. If you are contracting with a young person or someone whose mental state is unclear, request documentation or legal clarification.
2. You cannot waive your own competency Under Article 16, no person can voluntarily give up their legal competency or alter its rules. This means you cannot sign a contract that strips you of your fundamental legal rights under Saudi law.
3. Interdiction orders matter A court may interdict a person who is a spendthrift or financially reckless. If someone you are dealing with commercially has been interdicted, transactions with them may be limited or voidable. Check with a local legal professional if you are unsure.
4. Legal persons also have capacity Under Article 18, legal entities such as companies, associations, and public institutions also have defined legal capacity. When contracting with a Saudi company, ensure it is properly constituted and that the representative signing on its behalf has authority to do so.
Summary Table
| Category | Age / Condition | Capacity Level | |---|---|---| | Fully competent | 18+ Hijri, sound mind, no interdiction | Full | | Partially incompetent | 7–17 Hijri, or interdicted adult | Limited | | Fully incompetent | Under 7, or severe mental incapacity | None |
Final Tips for Expats
- Always work with a licensed Saudi legal professional when transactions involve minors or persons with mental health conditions
- If you are appointed as a guardian or trustee, understand that Saudi courts supervise these arrangements closely
- Keep copies of all written agreements, as Saudi law requires elected domicile and certain capacity-related arrangements to be in writing
