Definition
In law, parents are the legally recognized individuals bearing rights and obligations toward a child, including duties of care, support, and custody, and corresponding rights of decision-making, visitation, and inheritance. The legal definition has expanded substantially from its historical core:
1. Biological parents. The genetic father and mother of a child. Biological parentage creates a presumptive legal relationship in most jurisdictions, but it is neither necessary nor sufficient to establish full legal parent status in all contexts.
2. Legal parents. Individuals formally recognized by law as a child's parents, whether by birth, adoption, adjudication of paternity or maternity, or operation of a marital presumption. Legal parentage, not biology alone, determines rights and obligations enforceable in court.
3. Adoptive parents. Individuals who have acquired full parental status through the legal adoption process, with the same rights and duties as biological legal parents and, in most jurisdictions, the complete extinguishment of the prior biological parent relationship.
4. De facto parents / psychological parents. A category recognized in a growing number of jurisdictions for individuals who have functioned as parents in practice — forming a bonded parental relationship with the child — without formal legal status. Recognition varies widely; some states grant standing to seek custody or visitation, others do not recognize the category at all.
5. Presumed parents. Individuals whom the law presumes to be a parent based on circumstances, most classically a spouse or domestic partner at the time of a child's birth. Presumptions may be rebuttable or, in some contexts, conclusive.

Common Language
Modern common usage (Wiktionary): Plural of parent; a person's father or mother.
Historical common usage (Webster's 1913): A father or a mother; one who produces offspring; also, one who acts in the place of a parent.
The common meaning tracks biology almost exclusively, treating "parents" as simply the people who produced a child. The legal meaning diverges by making parentage a status that can be created, transferred, contested, and terminated through legal process entirely independent of biological fact. A person can be a legal parent of a child to whom they are not genetically related, and a biological progenitor may have no legal parent status whatsoever. Researchers who assume the common meaning applies in legal sources will miss these critical distinctions.

Common Confusion
Parents vs. guardians. A guardian has legal authority over a person or their property but does not hold the full bundle of parental rights and is subject to ongoing court oversight. Guardianship does not extinguish the legal parent relationship; parentage does not automatically create guardianship. The two statuses can coexist or exist independently.
Parents vs. custodians. A custodian exercises physical care and control, but custody is an allocable right that can be divided or awarded to non-parents. A parent who has lost physical custody remains a legal parent with continuing obligations and rights. Conversely, a non-parent may hold custody without holding parental status.
Biological parent vs. legal parent. Bouvier's definition conflates the two by defining parents as "lawful father and mother" and tying this to biological relationship. Modern law has thoroughly separated these concepts. A sperm donor, for instance, is typically a biological progenitor but not a legal parent; a same-sex spouse may be a legal parent with no biological connection whatsoever.

Why It Matters in Research
The term "parents" is one of the most unstable terms in family law, having undergone continuous legal redefinition across the twentieth and twenty-first centuries. Researchers face several traps:
Historical sources default to the marital, biological model. Bouvier defines parents as "lawful father and mother" — meaning the biological, married parents. Any source through the mid-twentieth century likely embeds this assumption. Rights of unmarried fathers, for instance, received virtually no constitutional protection until the 1970s. Research into parental rights before that period must account for the near-total invisibility of non-marital fathers in legal doctrine.
Jurisdictional divergence is severe and current. The recognition of de facto and psychological parents, the rights of same-sex parents, the treatment of intended parents in surrogacy arrangements, and the grounds and procedures for terminating parental rights differ dramatically across states and countries. No single definition of "parents" controls across jurisdictions, and this is an actively litigating area.
Termination of parental rights is an irreversible legal event that severs the parent-child relationship entirely — including inheritance, custody, and support obligations. When researching a historical document referencing "parents," researchers should determine whether a termination proceeding has occurred, as the legal parentage landscape can be wholly different from the biological one.
Assisted reproduction has generated an entirely new body of doctrine on "intended parents" and "genetic parents" that most pre-2000 sources do not address. Surrogacy agreements, donor conception, and embryo transfer cases may be controlling law for questions that older treatises address using entirely different frameworks.
The Law Mind Encyclopedia entries on de facto parentage and termination of parental rights provide critical context for understanding the edges of this term in contemporary research.

Historical Dictionary Support
Bouvier's entry is brief and reflects the classical common-law position: parents are "the lawful father and mother." Bouvier usefully distinguishes parents from ancestors (a broader category extending up the bloodline) and from predecessors (a corporate law term), clarifying that "parents" in legal usage was a precise, generationally limited, and maritally bounded concept. The citations to North Carolina and Pennsylvania reporters and to Vesey's Chancery confirm this was a settled term requiring little elaboration in early nineteenth-century practice precisely because its meaning was assumed to be obvious and biologically fixed.
What Bouvier's entry cannot reflect — and what no historical dictionary in the classical period could — is the constitutional transformation of parental rights from common-law duties into protected liberty interests, the legislative expansion of the category to include adoptive and then de facto parents, and the wholesale reconstruction of the concept driven by developments in reproductive technology and family diversity. Researchers using Bouvier for historical accuracy will find it reliable for its era; researchers using it as a guide to current doctrine will find it systematically incomplete.

Jurisdictional Note
Recognition of de facto and psychological parents as legal parents with standing to seek custody or visitation is a significant point of jurisdictional divergence — some states (including California and Washington) have codified or judicially recognized the doctrine, while others reject it entirely. Similarly, the rights of unmarried fathers, the treatment of intended parents in surrogacy, and the grounds for involuntary termination of parental rights are governed by state statute and vary substantially.
