The Saudi Civil Transactions Law states that legal personality begins at birth — specifically, from the moment a child is born alive (Article 3). This means that full legal rights attach at the point of live birth, and a stillborn child would not acquire independent legal rights under this framework.
However, the law also acknowledges that an unborn child may have rights that are determined by specific legal provisions (Article 3). In practice, this is most relevant in the context of inheritance and bequests: if a father dies while his wife is pregnant, the unborn child's potential share of the estate is typically reserved pending birth, in accordance with Islamic inheritance rules and related legal provisions referenced by the Civil Transactions Law.
For expat families, this means that if a family member passes away in Saudi Arabia and a pregnancy is involved, it is important to notify the relevant authorities and courts promptly so that the unborn child's potential entitlement is protected. Estate distributions should ideally not be finalized until after the birth. Consulting a Saudi-licensed lawyer experienced in inheritance matters is strongly recommended in such situations, as the interaction between civil law and Islamic personal status rules can be complex.
This is general legal information, not legal advice. For advice on your specific situation, consult a lawyer licensed in Saudi Arabia.
