Legitimacy (family law) — a simple overview

What legitimacy means
- Legitimacy is the status of a child born to married parents. In the past, a child born to parents who were not married (or who couldn’t marry) was called illegitimate or a bastard.
- In Scots law, terms like natural son or natural daughter were used for illegitimate children.
- Today, many countries have changed their laws so that being born outside marriage does not automatically limit a child’s rights.

Why legitimacy mattered in the past
- In many places, legitimacy determined who could inherit property, who could be next in line for titles, and who had certain legal rights.
- Over time, especially since the 1960s and 1970s, societies have become more liberal about marriage and birth outside of marriage.

Key legal changes by region

England and Wales
- Historically, illegitimate children had fewer rights and could not inherit real property.
- Legitimacy could be granted if the parents later married, under laws passed in the 20th century. These changes did not alter royal or noble succession.
- Since the 2000s, unmarried fathers can gain parental responsibility if they are named on the child’s birth certificate.

Scotland
- In the past, illegitimate children could be legitimized if their parents later married.
- The Legitimisation (Scotland) Act 1968 extended this idea, even when the parents were not free to marry.
- In 1986 and then 2006, Scottish reform abolished the legal status of illegitimacy for children, and such children have the same rights as others (including rights to inherit and to succession in some cases).

France and many parts of Europe
- France began reforms in the late 20th century, removing the label of illegitimacy and promoting equality between children born inside and outside marriage.
- In Europe, the European Convention on the Legal Status of Children Born Out of Wedlock sets out rights for children born outside marriage, and many countries have joined or aligned their laws with it.

Other places
- Many countries moved toward treating all children more equally, regardless of their parents’ marriage status.
- Nationality laws can still be affected by whether a child is born inside or outside wedlock in some places, though reforms have reduced these differences in many countries.

Inheritance, titles, and civil rights
- Inheritance rights have generally improved for children born outside marriage.
- Access to hereditary titles may still depend on the country’s rules about legitimacy, though practices vary and some reforms have reduced these distinctions.
- Civil rights for non-marital children have expanded in many jurisdictions, including equal access to public benefits and the ability to pass on property to the child.

Nationality and citizenship
- Some countries still differentiate citizenship based on parental marital status, though many have equalized these rules.
- In the United States, Supreme Court decisions in the 1970s and later led to stronger protections for children born out of wedlock, but some benefits or rules may still depend on jurisdiction.
- The United Kingdom began allowing citizenship through the father for children born to unmarried parents in recent decades (changes implemented around 2006).

Societal trends
- The share of births outside marriage has risen in many parts of the world, driven by secularization, women’s rights, and changing ideas about families.
- Marriage rates have declined in many OECD countries, while non-traditional family forms have become more common.
- Despite changes, some places still show stigma or legal challenges for children born outside marriage, though these are far less common than in the past.

Why this matters today
- Most countries aim to treat children equally, regardless of their parents’ marital status.
- Legitimacy may still affect certain rights in some areas (like specific hereditary rules or nationality in particular cases), but the trend is toward equality and non-discrimination for all children.

In short
Legitimacy used to shape important legal outcomes, from inheritance to citizenship. Now, many systems favor equal rights for all children, whether born inside or outside marriage. Changes continue to reduce the impact of a child’s parents’ marital status on their legal protections and opportunities.
