Short answer. When the law creating the juridical person or any other provision does not fix its domicile, Article 51 of the Civil Code places it at the location where its legal representation is established or where it exercises its principal functions — whichever applies.
What the law says
When the law creating or recognizing them, or any other provision does not fix the domicile of juridical persons, the same shall be understood to be the place where their legal representation is established or where they exercise their principal functions.

The default rule for juridical persons
Article 51 of the Civil Code supplies the rule when no other provision does: "When the law creating or recognizing them, or any other provision does not fix the domicile of juridical persons, the same shall be understood to be the place where their legal representation is established or where they exercise their principal functions." This default applies to corporations, associations, foundations, and any other entity treated as a juridical person under Philippine law. If the corporation's charter or the statute creating it already specifies a domicile, Article 51 does not come into play — it kicks in only when the question has no other statutory answer.
Two possible locations
Article 51 offers two alternative tests. The first is where the juridical person's legal representation is established — in practice, this typically means the registered office or the address given in the articles of incorporation. The second is where it exercises its principal functions — where the actual business operations are centered, where management decisions are made, and where the entity's main activities take place. If these two locations differ, determining which governs may depend on the particular issue being resolved — service of process, taxation, venue for suit, or other purposes that attach to domicile.
Why domicile matters for corporations
A juridical person's domicile is not merely an administrative detail. It determines where service of summons may be made, where certain tax obligations arise, which court has venue for cases involving the entity, and in some contexts whether the entity is considered a Philippine or foreign juridical person. For a company whose charter is silent on domicile, or whose registered address and actual operations are in different places, Article 51 provides the fallback rule. Clarity on this point is especially important in disputes where venue or jurisdiction is contested.
Who counts as a juridical person
Article 51 applies to juridical persons generally — not only stock corporations but also non-stock corporations, cooperatives, foundations, religious organizations, and government-created entities. Any entity that the law treats as a person capable of rights and obligations falls within its scope. For most private companies registered with the Securities and Exchange Commission, the principal office address stated in the articles of incorporation typically functions as the registered legal representation and is usually the starting point for determining domicile when no other provision settles the question.
