Legal framework
Switzerland allows marriage between all couples since 2022, Swiss and foreigner, heterosexual and homosexual. The foreign spouse's nationality is no obstacle, but procedures are more complex.
Common scenarios

- Relatively simple procedure
- Standard delay: 3–6 months
- B permit granted to spouse immediately
- No quota
Swiss + third-country foreigner
- More complex: prior authorisation needed
- SEM (State Secretariat for Migration) verification
- Delay: 6–12 months
- B permit granted after marriage if conditions met
Foreigner + foreigner resident in Switzerland
- Possible if both have valid residence permits
- Procedures similar to Swiss couples
Marriage abroad recognised in Switzerland
- Automatic recognition if Swiss conditions met
- Registration in Swiss civil registry via commune of residence

Recommended matrimonial regime
Default regime (participation in acquests) suits most binational couples. But consider:
Succession pact and marriage contract
Useful for:
- Significant assets in one country
- Children from previous union
- Major income/wealth differences
- Protection in case of return to country of origin
Separation of assets
Recommended if:
- Highly unequal wealth
- Professional risks (entrepreneur)
- Desire for strict mutual protection
Choice of applicable law
Possibility to choose applicable law (Swiss, spouse's, previous domicile) for succession and matrimonial regime under LDIP.
Binational couple taxation
Joint taxation in Switzerland
- Foreign spouse: taxed in Switzerland on worldwide income
- Unless specific bilateral agreement
- Risk of double taxation if assets or income in country of origin
Foreign wealth
- Declaration of worldwide wealth (Swiss wealth tax)
- Check double-taxation conventions
- Tax lawyer recommended if significant wealth
Simplified naturalisation of spouse
Foreign spouse married to a Swiss can apply for facilitated naturalisation:
- 3 years of marriage to a Swiss
- 3 years of Swiss residence
- Integration conditions: language B1 (oral) and A2 (written), knowledge of institutions
- Procedure: SEM (federal competence)
- Delay: 12–24 months
- Fees: CHF 600–2,000
Special cases
Civil + religious marriage
- In Switzerland, civil marriage mandatory BEFORE religious
- Religious ceremony has only spiritual value
Binational divorce
- Jurisdiction: court of common domicile (usually)
- LDIP: applicable law possibly from other country
- Maintenance, child custody: under Swiss law
- International recognition of decision
Children born abroad
- Recognition in Swiss civil registry
- Automatic acquisition of Swiss nationality if a parent is Swiss
- B permit for child if foreign parents resident in Switzerland
Tips
- Plan 6–12 months for procedures (third countries sometimes more)
- Legalise all documents in advance: apostille, translations
- International notary or lawyer recommended for assets or complex cases
- Prepare your spouse for Swiss culture: punctuality, formalism, community life
- Local language learning: essential for integration and naturalisation
- Keep all documents: useful for future naturalisation, succession, possible divorce
- Don't underestimate culture shock: integration takes 1–3 years on average
