Operative Concept
Presumption of existence links civil personality with capacity to act. A person shown to have civil personality is treated as legally existing, and therefore capable of being the subject of rights and obligations, until death or another legally effective fact is proved.
Capacity to act presupposes existence. Juridical capacity is the fitness to be the subject of legal relations; it is inherent in every natural person and is lost only through death. Capacity to act is the power to produce legal effects by one's own acts; it is acquired, may be restricted, and may be exercised personally or through lawful representation when the law so allows.
The presumption operates in favor of continuity. Once birth and life are established, the law does not require continuous proof that the person remains alive for every transaction or legal relation. The party who alleges death, nonexistence, minority, insanity, civil interdiction, or another legal restriction bears the burden of establishing the fact that defeats or limits capacity.
Existence, Personality, and Capacity
Existence for civil law purposes is not the same as full capacity to act. A newborn, a minor, or a person under guardianship has juridical capacity because each can own property, inherit, be supported, or be protected by law. They may lack full capacity to bind themselves personally, but their rights may be acquired, preserved, or enforced through parents, guardians, representatives, or the courts.
Birth determines civil personality. A conceived child is treated as born for purposes favorable to the child, provided the child is later born alive under the Civil Code rule on complete delivery. If the fetus had an intrauterine life of less than seven months, it is not deemed born if it dies within twenty-four hours after complete delivery.
The favorable treatment of a conceived child is a conditional legal protection, not actual capacity to act before birth. Rights such as inheritance, donations in favor of the unborn, support, or damages benefiting the child are preserved in suspense and become effective only if the statutory birth requirement is satisfied.
Death ends the natural person's juridical capacity. Obligations that survive death are enforced against the estate or legal successors in the manner provided by law, not because the deceased continues to act, but because patrimonial liability and succession are regulated after death.
Working Distinctions
| Concept | Legal Meaning | Practical Effect |
|---|---|---|
| Existence | The fact that a natural person has civil personality, beginning with birth and ending with death. | Existence makes the person a possible holder of rights and obligations. |
| Juridical capacity | The inherent fitness to be the subject of legal relations. | It cannot be removed by minority, insanity, interdiction, or similar restrictions. |
| Capacity to act | The ability to perform acts that produce legal effects by one's own will. | It may be restricted by age, mental condition, civil status, penalty, insolvency, agency rules, or other law. |
| Representation | The lawful performance of acts for a person whose rights require protection or whose personal capacity is limited. | The act is legally connected to the represented person when the representative acts within authority. |
Presumption in Favor of Capacity
A living person of legal age is presumed capable of acting unless a specific incapacity is shown. Capacity is the general rule because civil law favors stability of transactions, continuity of rights, and reliability of outward legal status.
Restrictions on capacity do not destroy personality. Minority, insanity or mental incompetence, deaf-mutism when relevant to understanding or communication, prodigality, civil interdiction, family relations, alienage, absence, insolvency, trusteeship, and similar conditions affect particular acts only to the extent fixed by law.
The legal effect of restricted capacity depends on the act involved. Some acts require representation; some contracts may be voidable because consent was defective; some dispositions may be unenforceable without required authority; and some legal disabilities merely prevent the person from exercising a specific office, privilege, or power.
Incapacity is generally assessed at the time of the act. A later diagnosis, appointment of a guardian, declaration of absence, or subsequent death may be evidence, but it does not automatically prove lack of capacity at an earlier moment unless the fact legally relates back or the evidence establishes the condition when the act was done.
Religious belief and political opinion do not limit capacity to act. Civil capacity is governed by law, not by conformity with a religious, ideological, or political position.
Absence and Continued Existence
Absence alone does not end existence. A person who leaves, disappears, or is unheard from continues to have civil personality until death is proved or legally presumed. During absence, the law protects the absentee's property, family, and legal relations through representation, administration, and special proceedings when necessary.
The presumption of continued life yields to statutory presumptions of death after the periods fixed by law. These presumptions are rules of necessity because rights over property, succession, marital status, and administration cannot remain indefinitely suspended when survival is unknown.
| Situation | Period | Effect |
|---|---|---|
| Ordinary absence where it is unknown whether the absentee still lives | Seven years | The absentee is presumed dead for civil purposes except succession. |
| Opening of succession after ordinary absence | Ten years | The absentee's succession may be opened when the longer succession period is satisfied. |
| Disappearance after the age of seventy-five | Five years for succession purposes | The shorter period reflects the stronger probability of death. |
| Person aboard a lost vessel, missing aircraft, missing in war, or exposed to other danger of death | Four years under the Civil Code | The person is presumed dead for all purposes, including division of the estate among heirs. |
| Remarriage of the present spouse under the Family Code | Four years of absence, or two years in danger-of-death situations | A judicial declaration of presumptive death based on a well-founded belief is required before the subsequent marriage. |
A presumption of death establishes a legal consequence, not necessarily the exact date, hour, or circumstances of death. When the precise time of death matters, the party relying on that fact must prove it by competent evidence.
If the absentee reappears, the presumption of death ceases to correspond to fact, but acts already done under law are not treated as nonexistent merely because the premise later changes. Property, succession, and marital consequences are then governed by the specific rules protecting good faith, registered acts, vested rights, and the absentee's recoverable interests.
Survivorship and Simultaneous Death
When rights depend on whether one person survived another, survival must be proved. In succession, if two persons are called to inherit from each other and it is doubtful which died first, the person who alleges prior death must prove it; absent proof, they are deemed to have died at the same time and no transmission of hereditary rights occurs between them.
This rule prevents inheritance from being built on speculation. The law will not presume that one person acquired rights from another unless survival, which is the factual basis of transmission, is established.
Survivorship is distinct from the broader presumption of continued existence. A person may generally be presumed alive until death is proved, but when two deaths are certain and only the order of death is uncertain, the law requires proof of priority if a legal consequence depends on that priority.
Effects on Legal Acts
Acts done by a person presumed existing and capable are generally respected until the contrary is established in the proper proceeding. This protects contracts, conveyances, court proceedings, civil registry entries, and property relations that depend on apparent legal capacity.
A transaction is not invalid merely because one party later dies, disappears, or is declared absent. The relevant inquiry is whether the person existed and had the necessary capacity when the act was performed, and whether any representative who acted for the person had authority at that time.
After death, no new personal act can be attributed to the deceased. Powers that are purely personal terminate, agency generally ends subject to protective exceptions, and pending rights are pursued by the estate, heirs, executor, administrator, or other person authorized by law.
For minors and persons under legal disability, existence supplies ownership and entitlement, while limited capacity determines how acts must be done. A sale, waiver, compromise, partition, or receipt involving their property may require parental authority, guardianship approval, court approval, or later ratification depending on the governing rule.
Proof and Legal Records
Civil registry records are the ordinary public evidence of birth, death, marriage, and related facts affecting existence and status. Registration is evidentiary; it records civil status but does not itself create natural personality or cause biological death.
When registry records are absent, defective, or disputed, existence, death, age, filiation, and capacity may be proved by competent evidence under the rules on evidence and civil registry correction. The strength of the presumption depends on the proven basic fact from which it arises.
Judicial declarations of absence, presumptive death, guardianship, nullity of acts, or settlement of estate do not create the underlying biological fact. They make the fact legally operative for specified civil consequences and allow courts, registries, heirs, spouses, creditors, and third persons to act on a legally recognized status.
For juridical persons, existence is not presumed from biology but from law, charter, registration, or the juridical act that creates them. Their capacity is measured by the law of their creation, their constituent documents, and the rules governing the particular juridical person.
