Swiss Family Law: Marriage, Divorce, Children

> Marriage and Matrimonial Regimes

Marriage conditions: In Switzerland, only civil marriage is recognized (celebrated by the civil registrar). The conditions are: be of age (18 years) or have authorization from the guardianship authority (from 16 years in exceptional cases), have capacity of discernment, not already be married, not have a close kinship. Mandatory preparations: three months after the marriage request, present identity documents, birth certificate extracts, certificate of capacity to marry for foreigners.

Legal regime: participation in acquests: This is the regime applicable by default without a marriage contract. Each spouse retains their own property (property acquired before marriage, inheritances, personal donations, personal effects). Property acquired during marriage forms acquests. In case of dissolution of marriage, each spouse takes back their own property, then each person's acquests are shared in half between the two spouses. This system balances autonomy and patrimonial solidarity.

Other matrimonial regimes: Community of property: all property and income become common (except strictly defined personal property). Rare in Switzerland, mainly used for cultural or succession reasons. Separation of property: each spouse retains ownership and management of their property. No sharing upon dissolution. Preferred by entrepreneurs, liberal professions or in case of significant patrimonial difference. The regime is freely chosen by notarized marriage contract, modifiable at any time.

Effects of marriage: Obligation of community of life (cohabitation, fidelity, mutual assistance). Contribution to household expenses according to each person's capacity (through work, income, wealth). Obligation to inform and consent for certain important acts: terminate the family home lease, commit family wealth, dispose of family home. In case of serious disagreement, possible referral to the court to decide or authorize an act.

Protection of the family home: The family home benefits from special protection. Even if only one spouse is tenant or owner, the other spouse must consent to: termination of the lease, sale or mortgaging of the home, substantial modification of rights to the home. The judge may authorize an act if the other spouse's refusal is abusive. This protection guarantees family stability.

> Separation and Protective Measures

De facto separation: Spouses may live separately without judicial proceedings. However, to regulate the consequences (maintenance contribution, child custody, housing), it is recommended to conclude a separation agreement or request protective measures of the marital union from the court. De facto separation does not dissolve the marriage; spouses remain civilly married and cannot remarry.

Protective measures of the marital union: If community of life is seriously threatened, a spouse may refer to the court to request: suspension of community of life with allocation of family home to one spouse, determination of child custody and visitation rights, determination of maintenance contributions for spouse and children, separation of property if necessary. These measures are provisional and can be lifted or modified. They facilitate an organized separation without rushing divorce.

Domestic violence: In case of physical, psychological, sexual violence or threats, the victim may request immediate expulsion of the violent spouse from the family home (art. 28b CC). Police may order a 2-week expulsion, renewable. The court may order a ban from approaching, contacting, or going to certain places for a determined period. Free emergency measures in certain cantons. Consultation centers and shelters available.

Separation agreement: Spouses may amicably regulate the consequences of their separation: distribution of debts, maintenance contribution, sharing of furniture, use of housing. The agreement must be written and can be approved by the court to be enforceable. It facilitates the transition and reduces conflicts. Note: it does not replace divorce judgment; it organizes the separation period until divorce or reconciliation.

> Divorce Procedure

Divorce by joint request: If spouses agree on the principle of divorce and its consequences (division of property, child custody, maintenance contributions), they file a joint request with a complete agreement. The court verifies that the interests of each party and the children are safeguarded. Fast procedure (3-6 months) and inexpensive (court fees CHF 500-1,500 depending on cantons). Spouses may be represented by a single lawyer or each by their own.

Unilateral divorce after 2 years of separation: If a spouse refuses divorce but the spouses have lived separately for at least 2 years, divorce may be pronounced without other reason. The separation must be effective (separate housing) and continuous. The court rules on the consequences of divorce (division, pensions) even if the defendant opposes it. Longer (6-18 months) and more expensive procedure (lawyer fees, possible expert reports).

Unilateral divorce for serious cause: A spouse may immediately request divorce without waiting 2 years if continuation of marriage has become unbearable: violence, severe alcoholism or addiction, abandonment, adultery with refusal to cohabit, total incompatibility. The applicant must prove the seriousness of the grounds. The judge examines whether community of life is objectively intolerable. Contentious and long procedure (12-24 months).

Consequences of divorce: Liquidation of matrimonial regime (sharing of acquests or property according to regime), sharing of occupational pension (2nd pillar) accumulated during marriage in half, determination of maintenance contributions for children and for ex-spouse if necessary, allocation of family home, distribution of debts, allocation of name (possibility to resume birth name or keep marital name). Divorce judgment is final after 30 days (possibility of appeal).

Divorce costs: Divorce by joint request with complete agreement: CHF 1,000 to 4,000 (court fees + lawyer fees if necessary). Contentious divorce: CHF 5,000 to 20,000 or more depending on complexity, duration of proceedings, expert reports (real estate valuation, wealth, earning capacity), multiple hearings. Free legal aid (court-appointed lawyer) possible for people without sufficient means.

> Parental Authority and Child Custody

Joint parental authority: Since 2014, joint parental authority is the principle, even after divorce or for unmarried parents. Both parents retain the right and duty to make important decisions concerning the child together: choice of school, education, health (medical interventions), religion, relocation abroad. Daily decisions are made by the parent with whom the child resides at that time.

Child custody and residence: Even with joint parental authority, the child resides mainly with one parent (sole custody) or alternately with both (shared custody). Sole custody: the child lives with one parent who ensures their daily life; the other has visitation rights (generally one weekend in two + half of holidays). Shared custody (week/week or other rhythm): parents must cooperate effectively, live nearby, and the child must be able to cope. The judge chooses according to the child's best interest.

Withdrawal or limitation of parental authority: The judge may withdraw or limit parental authority if the child's welfare requires it: serious neglect, abuse, inability to exercise authority (mental illness, dependence), parental conflict making any joint decision impossible. Withdrawal may be total (rare) or limited to certain decisions. Educational guardianship or tutorship may be instituted. Serious measure, ordered only if necessary for child protection.

Visitation rights and personal relations: The parent who does not have custody has the right and duty to maintain personal relations with the child. Standard visitation rights: one weekend in two (Friday evening to Sunday evening), half of school holidays, certain public holidays. This right may be extended or restricted according to circumstances. It may be exercised in the presence of a third party (supervised visit) if the child is in danger. Failure to respect visitation rights is punishable (fine, damages, modification of custody).

Relocation with child: The custodial parent cannot relocate far away with the child without the other parent's agreement or judge's authorization. Relocation abroad or to a distant region affects visitation rights. The judge examines: the reason for relocation (professional, family, personal), the child's interest (maintaining ties with both parents, stability, adaptation), the impact on the other parent. Authorization given if relocation is justified and personal relations can be maintained otherwise.

> Child Maintenance Contributions

Principle and calculation: Both parents must contribute to the child's maintenance according to their means (art. 276 CC). The parent who does not have custody pays maintenance covering: direct maintenance (food, housing, clothing, leisure, education), health expenses not covered by insurance, extracurricular activities, childcare costs. The amount depends on the child's needs (according to family standard of living before separation) and parents' financial capacities. Two-column method or cantonal flat rates.

Indicative amounts: Amounts vary by canton, age and needs. Example for a debtor's monthly net income of CHF 5,000-6,000: child 0-6 years: CHF 400-600, 7-12 years: CHF 600-800, 13-18 years: CHF 800-1,200, from 18 years in training: CHF 1,000-1,500. These amounts are indicative; the judge evaluates each case individually. In case of high income, the pension may be much higher. Revision possible in case of significant change in circumstances (change in income, increased needs).

Duration and modalities: Maintenance contribution is due until majority (18 years) or, if the child pursues adequate training, until completion (generally maximum 25 years). Adequate training: initial training corresponding to aptitudes and family prospects (apprenticeship, baccalaureate, university). If the child interrupts training without valid reason or undertakes no gainful activity, the obligation ceases. Monthly advance payment, possible indexation according to CPI or contractual clause.

Non-payment and legal remedies: In case of non-payment, the creditor parent may: summon the debtor in writing with deadline, refer to the maintenance contribution recovery office (MCRO) or cantonal advance service (which advances the pension and turns against the debtor), request debt enforcement and salary garnishment (absolute priority of maintenance), request driver's license withdrawal in case of persistent non-payment. Intentional non-payment may constitute a criminal offense (violation of maintenance obligation, art. 217 CP).

Modification of contribution: If circumstances change notably (increase or decrease in debtor's income, increase in child's needs, change in custody), each parent may request modification of contribution. The request must be addressed to the court that set the initial pension. Important and lasting change must be proven. Modification takes effect from introduction of request, not retroactively. Proceed quickly to avoid accumulation of arrears.

> Spousal Maintenance Contribution

Principle and conditions: After divorce, an ex-spouse may have to pay maintenance contribution to the other if they cannot provide for their needs through work, income or wealth. Conditions: the creditor cannot or with difficulty ensure their proper maintenance (according to marital standard of living), the debtor has the means after covering their own needs and those of children. Principle of "clean break": financial autonomy privileged, pension for ex-spouse should be temporary if possible.

Determination criteria: The judge examines: duration of marriage (long marriage → pension more likely and lasting), distribution of tasks during marriage (spouse who gave up career to care for family), age and health of creditor (professional reintegration possible?), education and professional experience, child custody (if creditor has custody of young children, earning capacity is reduced), professional reintegration prospects. Jurisprudential trend: favor autonomy, reduce or limit pension over time.

Amount and duration: The amount covers proper maintenance (housing, food, insurance, leisure, education) according to previous standard of living, within debtor's means. Duration: determined (e.g. 5 years to allow retraining) or undetermined (rare, for very long marriages with elderly or disabled person). Pension may be progressively reduced to encourage creditor to become autonomous. Cessation: creditor's remarriage, lasting cohabitation, regained financial autonomy, death.

Modification and legal remedies: As with children, contribution for ex-spouse may be modified if circumstances change notably: significant decrease or increase in debtor's income, improvement in creditor's situation (new job, inheritance), change in personal situation (health, remarriage). Procedure: reasoned request to the court. Voluntary non-payment may result in debt enforcement and sanctions. Lump sum payment (single benefit) possible by mutual agreement to replace monthly payments.

> Filiation and Child Recognition

Filiation of child born in marriage: A child born during marriage or within 300 days following its dissolution has as father the mother's husband (presumption of paternity, art. 255 CC). This presumption may be contested by action of disavowal within one year from knowledge of birth and the fact that one is probably not the father. The child may also contest their filiation after majority if they have doubts. DNA tests: possible by court order.

Paternity recognition: For a child born out of wedlock, the father must recognize the child to establish the filiation link. Recognition: declaration before the civil registrar, with mother's consent and child's consent if they have capacity of discernment. Recognition may be made before or after birth. It creates the same rights and duties as filiation in marriage: joint parental authority (if parents request it or live together), maintenance obligation, inheritance rights.

Action to establish paternity: If the father refuses to recognize the child, the mother or child may bring an action to establish paternity. The action must be brought before the child's majority (or within the year following majority by the child themselves). The court may order a DNA test. If paternity is proven, the judgment establishes filiation with retroactive effect: the father must pay back maintenance contributions, the child has inheritance rights.

Adoption: Adoption creates a complete filiation link between the adopter and the adopted, breaking (full adoption) or maintaining (simple adoption) ties with the birth family. Conditions: capacity to adopt (couple married for minimum 3 years or single person), thorough social investigation, child's interest at center. Long procedure (1-3 years) with follow-up by child protection authority. International adoption: subject to The Hague Convention, strict procedures. After full adoption, the adopted has the same rights as a biological child.

> Cohabitation and Registered Partnership

Cohabitation (common-law union): Cohabitation is not regulated by Swiss law. Cohabitants have no reciprocal legal rights or obligations: no mutual maintenance obligation, no sharing of property in case of separation (each keeps what they bought except proven co-ownership), no reciprocal inheritance rights (except testament), no right to the other's name. Recommendations: establish a cohabitation contract regulating sharing of expenses, ownership of property, and draft a will to protect the surviving cohabitant.

Children born in cohabitation: Joint parental authority applies automatically if parents make a joint declaration to the child protection authority or if the father recognizes the child and the parents live together. Otherwise, the mother has sole parental authority. The father has a maintenance duty from paternity recognition. In case of separation, the same rules as for divorced parents apply (maintenance contributions, custody, visits).

Registered partnership: Since 2007, same-sex couples may enter into a registered partnership before the civil registrar. Effects similar to marriage: obligation of assistance and contribution, matrimonial regime (participation in acquests or separation of property), inheritance rights, right to name, residence permit for foreign partner. Differences with marriage: no joint adoption of a child (except partner's child since 2018), no automatic joint parental authority over partner's child.

Marriage for all: Since July 1, 2022, same-sex couples may marry civilly in Switzerland. Marriage opens the same rights as for heterosexual couples: joint adoption, joint parental authority, medically assisted reproduction for female couples. Existing registered partnerships may be transformed into marriage by declaration to the civil registrar. Marriage for all equalizes family rights for all sexual orientations.
