How does a wife get pregnant by a man who is not her husband? What will be the status of the child?
Situation 1: By artificial insemination; if the wife and her husband complied with the 2nd paragraph of Article 164 of the Family Code, then the child is legitimate.
Situation 2: By sexual intercourse in a one-night stand or a live-in relationship while the marriage is subsisting; the child, however, is considered the legitimate child of the wife and her husband because of Article 164 of the Family Code (“children conceived or born during the marriage of the parents are legitimate”) and Article 167 (“the child shall be considered legitimate although the mother may have declared against its legitimacy or may have been sentenced as an adulteress”).
Situation 2 creates a big legal mess for the physically separated wife and husband. The wife no longer wants to have anything to do with her husband but the child is presumed to be legitimate. What surname will she use in the child’s birth certificate?
On the other hand, if the husband fails to comply with the periods stated in Article 170, then he (or his heirs) can no longer question the legitimacy of the child. The child will be entitled to inherit from him.
For children who may have been born in this kind of situation, they will find themselves in a limbo: they are legitimate from the legal point of view but are illegitimate biologically.
Most of you will probably say that of course, the child will be illegitimate. But I wish to discuss here several issues which give us a different answer:
 Conception as a result of artificial insemination
 Presumption of legitimacy of a child born during the marriage of the parents
 Ways legitimacy can be impugned or questioned
 DNA testing to prove legitimacy or illegitimacy
Conception as a result of artificial insemination
The 2nd paragraph of Article 164 of the Family Code states:
Children conceived as a result of artificial insemination of the wife with the sperm of the husband or that of a donor or both are likewise legitimate children of the husband and his wife, provided, that both of them authorized or ratified such insemination in a written instrument executed and signed by them before the birth of the child. The instrument shall be recorded in the civil registry together with the birth certificate of the child.Artificial insemination can either be AIH (artificial insemination by husband) or AID (artificial insemination by donor). Both husband and wife must have given their consent in a written document recorded with the Local Civil Registrar’s office. Firstly, I find it difficult to conceive, pardon the pun, of a woman being subjected to artificial insemination against her consent or willing participation. Secondly, if it is AIH, why would a written and recorded document still be necessary?
Why would couples resort to artificial insemination? Please take time to read the following articles by Sandra Glahn:

The first paragraph of Article 164 of the Family Code states that “children conceived or born during the marriage of the parents are legitimate”. This presumption can be disputed; Article 166 provides the grounds for questioning the legitimacy of a child. This presumption on legitimacy can however become conclusive as the Supreme Court explained in the case of Dizon vs. De Jesus G.R. No. 142877, October 2, 2001:
There is perhaps no presumption of the law more firmly established and founded on sounder morality and more convincing reason than the presumption that children born in wedlock are legitimate. This presumption indeed becomes conclusive in the absence of proof that there is physical impossibility of access between the spouses during the first 120 days of the 300 days which immediately precedes the birth of the child due to (a) the physical incapacity of the husband to have sexual intercourse with his wife; (b) the fact that the husband and wife are living separately in such a way that sexual intercourse is not possible; or (c) serious illness of the husband, which absolutely prevents sexual intercourse.The child is considered legitimate even though the mother has been convicted of adultery
The law favors the legitimacy of the child as Article 164 provides. Moreover, Article 167 provides that “the child shall be considered legitimate although the mother may have declared against its legitimacy or may have been sentenced as an adulteress.”
The law favors the legitimacy of a child
Please read carefully the 2005 Supreme Court decision in the case of “Gerardo Concepcion vs. Court of Appeals and Ma. Theresa Almonte.” In this case, Gerardo filed a case for declaration of nullity of his marriage to Theresa on the ground that their marriage was bigamous. Theresa was already married to a certain Mario when they got married (and Mario was still alive and living in Quezon City.) As a result, the trial court declared their son Jose Gerardo to be an illegitimate child. When the trial court denied Theresa’s motion to have Jose Gerardo’s surname changed to her maiden surname, she brought the case up to the Court of Appeals.
The CA ruled, to the shock of both Gerardo and Theresa, that Jose Gerardo was not the son of Ma. Theresa by Gerardo but by Mario during her first marriage. The CA ruling, later on affirmed by the Supreme Court, declared that every presumption must be in favor of legitimacy. The Supreme Court ruled that
During the period that Gerardo and Ma. Theresa were living together in Fairview, Quezon City, Mario was living in Loyola Heights which is also in Quezon City. Fairview and Loyola Heights are only a scant four kilometers apart.The Supreme Court ruled that it was only Mario (the first husband) or in the proper case, his heirs, who could question the legitimacy.
Not only did both Ma. Theresa and Mario reside in the same city but also that no evidence at all was presented to disprove personal access between them. Considering these circumstances, the separation between Ma. Theresa and her lawful husband, Mario, was certainly not such as to make it physically impossible for them to engage in the marital act.
Sexual union between spouses is assumed. Evidence sufficient to defeat the assumption should be presented by him who asserts the contrary. There is no such evidence here. Thus, the presumption of legitimacy in favor of Jose Gerardo, as the issue of the marriage between Ma. Theresa and Mario, stands.
Ways legitimacy can be impugned or questioned
Article 166 of the Family Code provides the ways by which legitimacy can be impugned or questioned:
(1) That it was physically impossible for the husband to have sexual intercourse with his wife within the first 120 days of the 300 days which immediately preceded the birth of the child because of:Periods within which to question legitimacy
(a) the physical incapacity of the husband to have sexual intercourse with his wife;
(b) the fact that the husband and wife were living separately in such a way that sexual intercourse was not possible; or
(c) serious illness of the husband, which absolutely prevented sexual intercourse;
(2) That it is proved that for biological or other scientific reasons, the child could not have been that of the husband, except in the instance provided in the second paragraph of Article 164; or
(3) That in case of children conceived through artificial insemination, the written authorization or ratification of either parent was obtained through mistake, fraud, violence, intimidation, or undue influence.
Article 170 provides for certain periods within which the husband can question the legitimacy of the child:
The action to impugn the legitimacy of the child shall be brought within one year from the knowledge of the birth or its recording in the civil register, if the husband or, in a proper case, any of his heirs, should reside in the city or municipality where the birth took place or was recorded.Briefly, the period is one year from the birth of the child if the husband or his heirs live in the same town or city where the child was born. The period is two years if the husband or his heirs if they reside elsewhere in the Philippines. The period is three years if the husband or his heirs are living abroad.
If the husband or, in his default, all of his heirs do not reside at the place of birth as defined in the first paragraph or where it was recorded, the period shall be two years if they should reside in the Philippines; and three years if abroad. If the birth of the child has been concealed from or was unknown to the husband or his heirs, the period shall be counted from the discovery or knowledge of the birth of the child or of the fact of registration of said birth, whichever is earlier.
Article 171 provides for the grounds whereby the husband’s heirs can question the legitimacy of the child:
The heirs of the husband may impugn the filiation of the child within the period prescribed in the preceding article only in the following cases:Can the action to question the legitimacy of a child be filed beyond the periods provided by Article 170? This question was raised in the 2000 case of “Teofista Babiera, petitioner, vs. Presentacion B. Catotal, respondent.” The Supreme Court clarified that:
(1) If the husband should die before the expiration of the period fixed for bringing his action;
(2) If he should die after the filing of the complaint without having desisted therefrom; or
(3) If the child was born after the death of the husband.
 Articles 170 and 171 of the Family Code apply to instances in which the father impugns the legitimacy of his wife’s child. The provisions, however, presuppose that the child was the undisputed offspring of the mother.
 These articles govern a situation where a husband (or his heirs) denies as his own a child of his wife. These articles do not contemplate a situation where a child is alleged not to be the child of nature or biological child of a certain couple.
DNA testing to prove legitimacy or illegitimacy; the need to amend Articles 170 and 171 of the Family Code
What these provisions of the FC are saying is that if the period (one, two or three years) has already passed, the husband or his heirs can no longer question the legitimacy of the child. These periods provided by the Family Code, as far as I can recall, were taken verbatim from the New Civil Code of the Philippines. The NCC became effective in 1949 while the Family Code became effective in 1998. As far as I can recall from my Persons and Family relations class in MLQU in 1987-88, these periods were provided because of the fickleness of human memory.
Today, however, DNA testing can very easily determine the paternity of children. This is one area where the Family Code has not kept pace with technology. Perhaps our senators and congressmen can modify Article 170 of the Family Code so that any father who wants to question the legitimacy of a child can do so even beyond these periods.
