Common Legal Mistakes
Many individuals commit costly legal errors due to a lack of knowledge about Swiss law. The most common include: failing to respect deadlines (30 days to challenge a dismissal or termination of a lease), not documenting agreements in writing (an oral contract is valid but difficult to prove), not preserving evidence (correspondence, receipts, photos), signing without reading (especially the general terms and conditions), failing to seek legal assistance when entitled to it, and confusing Swiss law with that of their country of origin.
Other mistakes include: not timely enrolling in health insurance, failing to declare auxiliary income to the tax authorities, subletting without the landlord's authorization, and not contesting a penal decree thinking it is merely a fine.
Frequently Asked Questions
What is the most serious mistake in Swiss law?
Failing to Respect Deadlines. In Switzerland, many deadlines are imperative (30 days to appeal, 6 months to bring a complaint). Once these have passed, the right is lost permanently.
Does an oral agreement have legal value in Switzerland?
Yes, the majority of contracts are valid orally (art. 1 CO). However, certain contracts require written form (real estate, art. 216 CO) or authentic form (marriage, art. 184 CC). The problem is always proof.
Is a lawyer's consultation required for everything?
Not necessarily. For minor disputes, the conciliation authority and free legal information services may be sufficient. For complex matters or those with strict deadlines, a lawyer is recommended.
