*248 Opinion
In this appeal we decide whether a husband (WPA) who is not the biological father of his wife’s child can be required to support the child after divorce when he has reared and supported the child for the five years since birth under the false belief that he was the child’s father. In the divorce proceeding the trial court ordered, pursuant to Code § 20-49.3, that the wife (NPA), the husband, and two children submit to the human leukocyte antigen (HLA) blood test to determine paternity. The HLA test results established conclusively that the husband was not the biological father of the five year old male child, but was the father of the three year old daughter. The trial court ruled that the husband is not liable for the support of his former wife’s son. No issue is raised concerning the daughter.
On appeal the wife contends that her former husband should be required to support the child based on one of several legal theories applied in similar cases in Virginia or other jurisdictions: (1) common law adoption; (2) in loco parentis; (3) implied contract; or (4) equitable estoppel. We find that on the facts before us none of these doctrines provide a basis to require the husband to support the child. Thus, the trial court properly ruled that the husband was not liable for support of the son.
The parties married in September 1977. They had marital problems which caused them to separate between April 1980 and 1981, during which time both parties dated other people. They reconciled and resumed cohabitation in 1981. The wife testified that, before the reconciliation, she told her husband that in October 1980 she had sexual intercourse with another man. She testified that during the separation she and her husband also had sexual intercourse on numerous occasions. Shortly after their reconciliation the wife discovered that she was pregnant. She gave birth to a son in May 1981. She testified that her husband was upset by her pregnancy. She told him that if he had any doubts about being the father he should have a blood test while she was in the hospital, but if he did not he should never again raise the issue. The husband testified that he accepted as true his wife’s statement that he was the child’s father and did not request that the blood test be administered. After the child’s birth, the parties resumed their marriage and proceeded with the responsibility of rearing the child. The parties gave the child the husband’s sur *249 name. Both parties testified that the husband treated the child as his own son throughout the remaining years of the marriage. A second child, a daughter, was born to the marriage a few years after the son’s birth.
In May 1985 the wife filed for divorce and requested child and spousal support, child custody and equitable distribution. The parties agreed upon temporary support and child custody. The husband filed an answer and cross-bill alleging that the wife caused the dissolution of the marriage. In an amended cross-bill he also alleged that he was not the biological father of the two children. The trial court ordered HLA testing. The results of the HLA test established that the husband was the biological father of the daughter, but that it was genetically impossible for him to be the natural father of the male child. The trial court granted the wife a divorce, ordered the husband to pay spousal support and $250 per month child support for the daughter. Based on the HLA test results, the trial court found that, because the husband was not the biological father of the child, and because he had neither adopted the child nor contracted to support the child, he had no legal support obligation. The wife challenges the trial court’s child support ruling and contends that the husband has assumed and owes a legal duty to support her son.
The general rule in Virginia is that a parent owes a duty of support only to his or her natural or legally adopted child.
See T. . . v. T.
. .,
The appellant argues, however, that regardless whether the husband is her son’s biological father, this court should hold that he has a legal duty to support the child under one of the four theories mentioned by the Virginia Supreme Court in
T. .
. v.
T.
. .,
First, we find no support in T. . . for the theory of common law adoption. With regard to the other theories mentioned in T. . ., we need not decide whether they were in fact approved. On the facts of the case, we conclude that they would not require the husband to support this child.
I.
Adoption in Virginia is solely a creature of statute. The common law as it developed in Virginia did not recognize adoption other than by statutory process.
Harmon
v.
D’Adamo,
*251 II.
The theory of
in loco parentis,
provides, in effect, that a stepparent or one who knowingly and voluntarily assumes the role of parent to a child may obtain certain legally cognizable rights and obligations the same as if between “a parent and child” but only so long as the relationship which gave rise to the rights and duties continues to exist.
Doughty
v.
Thornton,
The husband did not knowingly and voluntarily accept another man’s child into his care.
See id.
at 792,
Furthermore, when the relationship which brought about the status of
in loco parentis
is terminated, “the reciprocal rights, duties, and obligations of parent and child” do not survive independent of the relationship, except by agreement or goodwill.
Doughty,
*252 III.
Next the wife argues that the discussion with her husband at the hospital shortly after the child’s birth about having a blood test to determine paternity constituted an implied contract by the husband to accept and support the child as his natural son. The trial court did not find on these facts that the husband agreed to support the wife’s child regardless of whether he was the natural father.
In
T. .
. v.
T. .
., the Court found that an expressed oral contract was entered between the parties that if the expectant mother would forego her plans to place the child by another man for adoption, forego her plans to move to New York where she had employment, and marry him that he would accept the child into the family and rear the child “as if it were his own.”
Here the husband accepted his wife’s son into his home on the mistaken assumption that the child was his own. His inaction or silence after his wife raised the possibility of a blood test to determine paternity did not cause her to act to her detriment. Likewise, his conduct cannot be considered an implied agreement to support the child if he were not the natural father. To enforce a duty of support on the husband based upon a theory of express or implied oral contract, we must be able to ascertain from the record that the husband knowingly and intentionally entered into an agreement with the wife to support her illegitimate child.

IV.
Finally, the wife argues that the husband should be barred or equitably estopped from denying his duty to support the child. Virginia courts have never applied a doctrine of equitable estoppel in the context of child support cases; however, a number of other jurisdictions have relied upon estoppel principles to prevent a husband from repudiating his voluntary commitment to support his wife’s illegitimate child.
See In re Marriage of A.J.N. & J.M.N.,
Although the husband had assumed the role of father for the child’s entire life, he did not knowingly misrepresent to the child that he was his natural father.
See M.H.B. v. H.T.B.,
100 N.J. at -,
Accordingly, for the reasons stated above we affirm the trial court’s holding that the husband is not liable to support the wife’s illegitimate son.
Affirmed.
Koontz, C.J., and Benton, J., concurred.
