This page explains the law in force; it does not replace individual legal advice. SIP provides no legal representation in an individual case within the meaning of the Federal Act on the Freedom of Movement of Lawyers (LLCA, SR 935.61).

What this is about
When a child is born in Switzerland, three legal questions arise that must all be answered at the same time:
- Which citizenship does the child acquire? — a citizenship question, governed by the Federal Act on Swiss Citizenship (Swiss Citizenship Act, SCA, SR 141.0).
- Is the child entered in the Swiss civil-status register? — a civil-status question, governed by the Swiss Civil Code (CC, SR 210) and the Civil Status Ordinance (CSO, SR 211.112.2).
- Which residence permit does the child receive if it does not acquire Swiss citizenship? — a foreign-nationals-law question, governed by the Federal Act on Foreign Nationals and Integration (Foreign Nationals and Integration Act, FNIA, SR 142.20), the Ordinance on Admission, Residence and Gainful Employment (OASA, SR 142.201) or the Agreement on the Free Movement of Persons (AFMP, SR 0.142.112.681) for EU/EFTA families.
These three questions are as a rule dealt with within a single procedural sequence at the civil registry office and the cantonal migration office — the order, however, is legally precise and delicate in a blended-family case.
Three basic constellations
The treatment under foreign-nationals law and citizenship law follows the citizenship and residence status of the parents.
Constellation A — At least one legal parent is Swiss
The child acquires Swiss citizenship from birth under Art. 1 SCA (ius sanguinis principle — acquisition by descent). There is no permit question, because the child has no foreign-national status.
Constellation B — Both legal parents are foreign nationals holding a residence permit
The child as a rule receives a residence permit derived from the parents' status (family reunification under Arts. 42–44 FNIA or Art. 3 Annex I AFMP). There is no automatic Swiss citizenship through mere birth in Switzerland — Switzerland does not follow the ius soli principle.
Constellation C — Both legal parents are foreign nationals without regular status (N, F, S, refugee-B or undocumented)
The child receives the status derived from the track of the parent holding the main permit (family asylum under Art. 51 AsylA or permits derived from asylum law). Where the parents are undocumented, the question of civil-status registration arises separately from the foreign-nationals-law question — see the Asylum Act glossary and the hardship-case rules under Art. 30 FNIA.
Swiss citizenship by birth (Constellation A)
The norm — Art. 1 SCA
Art. 1 para. 1 SCA states in essence: a person is Swiss from birth if at least one of their parents holds Swiss citizenship.
What is decisive is the legal parent-child relationship at the time of birth — that is, not necessarily biological descent, but the filiation recognised under civil-status law.
Married Swiss father or Swiss mother
Where the parents are married and at least one of them is Swiss, the child automatically acquires Swiss citizenship at birth. Registration with the civil registry office is triggered by the hospital (birth notification within the statutory time limit). The parents bring their identity and civil-status documents; the civil registry office enters the birth in the Swiss civil-status register (Infostar) and records the citizenship.
Unmarried Swiss father
Where the parents are unmarried, the rule is more differentiated:
- If the mother is Swiss, the child automatically acquires Swiss citizenship at birth (Art. 1 para. 1 SCA).
- If only the father is Swiss and the mother is a foreign national, the child acquires Swiss citizenship only once legal paternity is established — through recognition of paternity under Art. 260 CC or through a judgment establishing paternity. Whether and how a recognition declared only after birth causes the acquisition of citizenship to take retroactive effect as of the time of birth is assessed according to the conditions of the Swiss Citizenship Act and the relevant transitional provisions; this consequence must be clarified in the individual case with the civil registry office before any advice is given.
In this constellation, the order is decisive: if the recognition of paternity is declared before or immediately after the birth, the filiation to the Swiss father is documented from the outset; if the recognition is delayed, the child may in the meantime hold only the mother's citizenship — which can have consequences for travel, insurance and residence status.
Important clarification — no ius soli
Switzerland does not follow the ius soli principle. Birth on Swiss soil does not on its own confer Swiss citizenship. This is frequently misunderstood in practice — notably by parents from states that recognise the ius soli principle (for example the USA, Canada and several American states). Clara must communicate this precisely for every citizenship question.
Blended families — stepchildren
The Swiss citizenship of a step-parent does not pass to the stepchild. Stepchildren acquire citizenship only through adoption (Art. 4 SCA) or through facilitated naturalisation under the conditions of Art. 21 SCA and the following provisions. Mere marriage of the biological parent to a Swiss person confers no citizenship status on the child.
Birth notification — procedure
The birth of a child sets off a chain of notifications. The order is prescribed by law in both civil-status matters and foreign-nationals law.
Step 1 — Birth notification by the hospital
The hospital in which the child is born is obliged to notify the birth, within the statutory time limit, to the competent civil registry office. This birth notification contains the mother's personal data, the date of birth, the place of birth and details of the child. The exact notification deadline and the procedure follow from the Civil Status Ordinance (CSO, SR 211.112.2); the specific deadline must be requested from the competent civil registry office.
In the case of a home birth or a birth while travelling, the competent persons (midwife, doctor, in an emergency a parent) assume the notification obligation.
Step 2 — Entry in the civil-status register
The parents are requested by the civil registry office to submit their identity and civil-status documents:
- valid identity documents (passport or identity card);
- family certificate, marriage certificate or certificate of single status;
- for foreign documents: where applicable, translation and legalisation or apostille.
The civil registry office enters the child in Infostar, the Swiss civil-status register.
Step 3 — Recognition of paternity for unmarried parents
Where the parents are not married, the father may formally recognise paternity (Art. 260 CC). This may take place before the birth (prenatal recognition) or after the birth, at the civil registry office at the mother's place of residence or the child's place of birth. The recognition is entered in Infostar.
In a Swiss-foreign constellation, the recognition is the legally constitutive element for any acquisition of citizenship through the father (see above — unmarried Swiss father).
Step 4 — Registration of citizenship
If the child acquires Swiss citizenship by birth, the citizenship is entered in the civil-status register together with the place of origin and the canton of origin. The parents subsequently receive a confirmation; a Swiss identity card or passport is applied for separately at the competent cantonal identity-document office.
Step 5 — Permit application (Constellation B or C)
If the child does not acquire Swiss citizenship, it is subject to the registration obligation under foreign-nationals law. This registration obligation follows from Art. 12 FNIA; the time limits are set by the Federal Council in the ordinance (OASA, SR 142.201) and by the competent cantonal migration office. In practice, the birth of a foreign child must be notified to the competent cantonal migration office within a few days — the exact deadline (often on the order of two weeks from birth) must be requested from the competent cantonal migration office; the permit is then issued.
The parents typically submit:
- the child's birth certificate;
- copies of both parents' permits;
- where applicable, the marriage certificate;
- in the case of unmarried parents: the certificate of recognition of paternity.
The processing time varies from canton to canton and, in experience, falls within the range of a few weeks; binding information is provided by the competent cantonal migration office.
Permit derivation where both parents are foreign nationals (Constellation B)
The permit assigned to the child follows the parents' status. The practice of the authorities can be summarised as follows in the three main constellations — what is binding is always the decision of the competent cantonal migration office in the individual case.
Both parents with a C settlement permit
The child as a rule receives a C settlement permit. The legal basis is Art. 43 FNIA in conjunction with the cantonal practice on the direct grant of a C permit to children born in Switzerland to C-permit parents.
Both parents with a B residence permit
The child as a rule receives a B residence permit (family reunification under Art. 44 FNIA for third-country parents, or Art. 3 Annex I AFMP for EU/EFTA parents).
Mixed constellation — one parent C, the other parent B
Practice varies from canton to canton. Several cantons grant a C permit to the child in this constellation where the C-permit parent is legally the parent holding the main permit and the family is predominantly carried by that parent's status. Other cantons issue a B permit at first and hold out the prospect of an upgrade to a C permit at the point in time when the child meets the ordinary C-permit conditions. This question must be clarified in the individual case with the competent cantonal migration office.
Parents with AFMP status (EU/EFTA nationals)
The child receives a B EU/EFTA permit as a family member under Art. 3 Annex I AFMP. The right of residence exists for descendants up to the age of 21 — or beyond, where the child is in education or is in fact supported by the EU/EFTA parent.
Parents with mixed third-country/EU status
Here the FNIA and the AFMP combine. The applicable legal basis depends on which parent legally constitutes the "anchor". Cantonal practice is nuanced; what is decisive are the directives of the State Secretariat for Migration (SEM) in force at the time, which must be consulted regularly.
Family reunification — overview of the legal bases
The permit derivation of the child born in Switzerland is, from the systematic standpoint of the law, a form of family reunification under Arts. 42–44 FNIA or Art. 3 Annex I AFMP, even though the child does not "join" the family but is born to the parents.
| Norm | Scope of application | Entitlement / discretion |
|---|---|---|
| Art. 42 FNIA | Family reunification with Swiss nationals (relevant in Constellation A for any foreign siblings, but not for the child born in Switzerland itself) | Entitlement (for unmarried children under 18) |
| Art. 43 FNIA | Family reunification with holders of a settlement permit (C) | Entitlement (for unmarried children under 18) |
| Art. 44 FNIA | Family reunification with holders of a third-country residence permit (B) | Discretion — conditions include: living together, suitable housing, sufficient financial means, where applicable proof of language skills |
| Art. 3 Annex I AFMP | EU/EFTA family members | Right of residence — children up to the age of 21, beyond that in the case of education or support |
| Art. 51 AsylA | Family asylum — children of recognised refugees | Inclusion under specific conditions |
In terms of time limits, Art. 47 FNIA (time limit for family reunification) does not apply to the child born in Switzerland, whose status follows directly from the birth notification. The family-reunification time limit of Art. 47 FNIA is relevant for siblings to be brought in later who were born abroad — see the time-limits table of Swiss migration law.
Registration obligation and time limit
The registration obligation under foreign-nationals law follows from Art. 12 FNIA; the registration time limits are set, under Art. 12 para. 3 FNIA, by the Federal Council in the ordinance (OASA, SR 142.201), and the competent cantonal authority conducts the procedure. In practice, this means, on the birth of a foreign child in Switzerland:
- the birth must be brought to registration within a short time limit (often on the order of two weeks from birth — binding is the information of the competent cantonal migration office);
- the registration is as a rule initiated in parallel with the civil-status entry;
- in the event of an omission, a subsequent registration is possible, in the individual case combined with a report for a contravention and a fee.
The exact cantonal handling varies — some cantons link the civil-status registration and the migration registration in a single set of forms, others conduct the procedures separately.
Recognition of paternity in detail
Prenatal recognition
A recognition of paternity is possible before the birth (prenatal recognition). It is declared at the civil registry office and recorded subject to the birth. This may come into consideration in particular in a Swiss-foreign constellation, so that the child is entered at birth immediately with the Swiss filiation; the legal consequences must be clarified in the individual case with the civil registry office.
Recognition after the birth
Recognition after the birth is equally possible. It establishes legal filiation and is subsequently entered in the civil-status register. In the case of subsequent recognition by a Swiss father, the citizenship-law effect must be clarified in the concrete case with the civil registry office (Art. 1 SCA as well as the relevant transitional provisions of the Swiss Citizenship Act).
International constellations — PILA
Where there are cross-border facts (e.g. foreign father, birth abroad, recognition by a foreign authority), the Federal Act on Private International Law (PILA, SR 291) applies. A recognition declared abroad or a foreign paternity judgment can be recognised in Switzerland — the conditions are strict and must be clarified, before any advice, in the individual case with the civil registry office and a lawyer.
Adoption and Swiss citizenship (Art. 4 SCA)
Where a foreign child is adopted by a Swiss person, the child acquires Swiss citizenship with the adoption — Art. 4 SCA. This applies to:
- the adoption of minors under Swiss law;
- foreign adoptions that are recognised in Switzerland (Hague Adoption Convention of 29 May 1993, SR 0.211.221.311, in conjunction with the PILA, SR 291).
Stepchild adoption (adoption of the child of the spouse or of the registered partner) can likewise lead to the acquisition of citizenship, provided the civil-law adoption conditions are met.
Cross-link: a dedicated file on adoption is in the backlog; until its publication, Clara refers to the civil registry office and to the SEM topic page on citizenship.
Citizenship in the case of unmarried foreign parents
Where both parents are foreign nationals and unmarried, the child's citizenship is determined according to the citizenship law of the parents' state or states of origin. Switzerland registers the child with the citizenship that the state of origin confers on it; often this law ties citizenship to descent from the mother, but the exact consequence must always be examined according to the foreign law.
Statelessness risk
In some countries of origin, a child does not automatically acquire the citizenship of the mother or the father — notably where the law of origin provides for strictly patrilineal ius sanguinis and the father is absent or declares no recognition. In these constellations, a child may come into the world stateless.
Statelessness is a vulnerable constellation that establishes specific rights (Convention of 28 September 1954 relating to the Status of Stateless Persons, SR 0.142.40). Where there is a suspicion of a statelessness risk, Clara refers the parents without delay to the cantonal civil registry office, to the State Secretariat for Migration (SEM) and to specialised bodies (for example UNHCR Switzerland and Liechtenstein). Which countries of origin recognise a strictly patrilineal ius sanguinis law changes continually and must be examined in the individual case on the basis of current sources (in particular the UNHCR mapping and SEM practice).

Dual citizenship
Switzerland permits dual and multiple citizenship. A child who acquires Swiss citizenship and at the same time holds the citizenship of another state retains, from the Swiss standpoint, both.
Important: the state of origin may, for its part, refuse dual citizenship or provide for a loss of the original citizenship upon acquisition of another. Parents who are keen for the child to retain the citizenship of the state of origin must examine the citizenship law of that state separately — Switzerland can give no information on this.
School, health insurance and family allowances
With the birth, obligations and entitlements outside foreign-nationals law arise that concern every family regardless of permit status:
Health insurance
The Federal Health Insurance Act (HIA, SR 832.10) provides for compulsory insurance from birth. Affiliation must take place within three months but takes retroactive effect as of the day of birth. The choice of insurer is free; children's premiums vary depending on the insurer and the premium region. Cross-link: the basics of health insurance (to be created).
Family allowances
Family allowances are based on the Federal Family Allowances Act (FamAA, SR 836.2) and the cantonal implementing legislation. An entitlement as a rule exists for every child from birth — the amount and the basis of entitlement vary by canton and by the parents' employment status. Registration typically takes place through the employer or the cantonal family compensation fund.
Compulsory schooling
Compulsory schooling is regulated at cantonal level and as a rule begins with entry into the compulsory entry level (kindergarten or basic level); the entry age is determined by cantonal law. It applies regardless of the child's residence status — even children without regular status are entitled to basic education and are subject to compulsory schooling (fundamental right to sufficient and free basic education under Art. 19 SR 101 of the Federal Constitution, Cst.).
Children of parents on the asylum track
For parents on the asylum track, the permit derivation follows the status of the parent holding the main permit:
| Parents' status | Child's status |
|---|---|
| N (asylum seeker) | N |
| F (provisional admission) | F |
| S (person in need of protection) | S |
| refugee-B (recognised refugee with B) | Family asylum under Art. 51 AsylA, as a rule as refugee-B |
For refugee parents, Art. 51 AsylA (family asylum) is the central norm — it provides for inclusion in refugee status for the closest family members, to the extent that no special circumstances stand in the way.
Cross-link: the Asylum Act glossary for the detailed treatment. Asylum-track constellations are highly sensitive; for every asylum-related question concerning the birth, Clara refers to specialised legal advice services (Swiss Refugee Council OSAR, cantonal asylum advice services).
Facilitated naturalisation for the 3rd generation (Art. 24a SCA)
Young foreign nationals of the third generation who were born in Switzerland and grew up here may, under specific conditions, file an application for facilitated naturalisation under Art. 24a SCA (in force since 15 February 2018).
The conditions include, among others:
- the applicant was born in Switzerland;
- at least one grandparent has lived in Switzerland or acquired a right of residence there;
- at least one parent has shown a certain length of residence in Switzerland, a right of residence and part of their schooling in Switzerland;
- the applicant has themselves attended part of compulsory school in Switzerland;
- the application is filed before reaching an age limit set by law.
The exact thresholds (length of residence of the grandparents and parents, duration of schooling, age limit) follow from Art. 24a SCA and the Ordinance on Swiss Citizenship (Citizenship Ordinance, CitO, SR 141.01) and must be examined in the individual case against the wording in force. The provision goes back to the popular vote of 12 February 2017 and was subsequently transposed into the SCA and the CitO.
This procedure is not the subject of the birth constellation itself, but a later option for the child — Clara refers to the SEM topic page on citizenship and to the cantonal naturalisation authority.
Blended families and co-parenthood
Stepfamilies
On the birth of a child within a blended family, the legal parent-child relationship is the decisive connecting element — not living together. A step-parent does not become a legal parent in civil-status terms except through adoption.
Marriage for all and same-sex parenthood
Since the entry into force of "marriage for all" on 1 July 2022, same-sex couples can marry in Switzerland. If the mother is, at the time of the birth, married to a woman and the child was conceived by sperm donation under the Reproductive Medicine Act (RMA, SR 810.11), the mother's wife is deemed to be the other parent — Art. 255a CC. The exact conditions and transitional arrangements must be clarified in the concrete case with the civil registry office.
Surrogacy
Surrogacy is prohibited in Switzerland (Art. 119 SR 101 of the Federal Constitution, Cst., in conjunction with the Reproductive Medicine Act, RMA, SR 810.11). Surrogacy arrangements carried out abroad are not recognised without further ado in Switzerland, and the legal parent-child relationship is examined by the Swiss civil registry office and, where applicable, by the courts. This constellation is highly sensitive — Clara refers without delay to the civil registry office and to a specialised lawyer.
Procedural notes
- The birth notification at the civil registry office is triggered by the hospital — the parents must keep their identity and civil-status documents ready.
- In the case of unmarried parents, the recognition of paternity can be declared before or immediately after the birth; this helps to avoid order-related complications (travel with the child, citizenship question, permit question). Whether and when a recognition is declared is an individual decision, to be discussed with the civil registry office and, where applicable, with a lawyer.
- The foreign-nationals registration of the child (permit application) takes place in parallel, within the time limit set by the cantonal migration office.
- Affiliation to health insurance takes place within three months but takes retroactive effect as of the day of birth.
- In the event of any suspicion of a statelessness risk, unclarified paternity or a blended-family complication, legal support must be sought without delay.

- No advice on statelessness strategy in the individual case — referral to the SEM and to UNHCR.
- No paternity strategy advice (e.g. whether the recognition should be declared before or after the birth, and with a view to which consequences). Such decisions require the civil registry office and a lawyer.
- No citizenship-optimisation advice concerning 3rd-generation naturalisation — this question requires a full review of the file and a referral to the cantonal naturalisation authority.
- No representation before the civil registry office, the cantonal migration office or a court.
- No legal information on the recognition of foreign adoptions or surrogacy arrangements — direct referral to the civil registry office and to a specialised lawyer.
