Leases & real estate: the clauses that change everything, residential or commercial
Security deposit, notice period, commercial lease statute, co-tenancy: the regimes not to confuse.
A residential lease and a commercial lease don't follow the same rules — duration, termination, rent review. Confusing the two regimes, or simply misreading a clause, gets costly over several years.
Quick check: Analyze your lease on subblink — security deposit, notice period, indexation, mandatory particulars.
1. Residential lease: security deposit and notice period
Legal reminder (France)
Security deposit capped at 1 month's rent excluding charges for an unfurnished property, 2 months for a furnished one. Legal notice period of 3 months for unfurnished, 1 month for furnished (ALUR Act).
Legal reminder (Switzerland)
The rent security deposit is capped at 3 months' rent, deposited into a blocked account in the tenant's name (Art. 257e CO). Abusive termination is governed by Art. 271-271a CO.
What subblink detects
Security deposit amounts and notice periods are compared to the legal caps applicable per the country and type of housing identified.
2. Commercial lease: a completely different regime
The problem
An entrepreneur signing their first commercial lease sometimes mistakenly applies the reflexes of a residential lease — while the regime is structurally different.
Legal reminder (France)
The commercial lease statute requires a minimum 9-year term with a tenant's right to terminate every three years (Art. L145-1 et seq. of the Commercial Code), a right to renewal with eviction compensation if refused, and a rent review cap based on the ILC or ILAT index.
Legal reminder (Switzerland)
There is no equivalent protective statute: contractual freedom is broad (Art. 253-274g CO), with only the general lease rules as a safeguard (abusive termination, Art. 271 CO).
What subblink detects
The lease type (residential or commercial) is identified from the text, with the expected clauses specific to each regime.
3. Co-tenancy: joint liability limited in time
The problem
A co-tenant who leaves the property remains jointly liable for the rent longer than they think if they don't know the legal limit.
Legal reminder (France)
The joint liability of a departing co-tenant is limited to 6 months after their departure if a replacement isn't found (ALUR Act, Art. 8-1 of the 1989 Act).
What subblink detects
The presence of a joint-liability clause and its time limit, if mentioned in the co-tenancy lease text.
4. Sale agreement: conditions precedent
The problem
A sale agreement subject to conditions precedent (loan approval, pre-emption right waiting period) has precise deadlines — missing them can forfeit the benefit of the condition.
Legal reminder (France)
A 10-day withdrawal period is granted to a non-professional buyer (Art. L271-1 of the Construction and Housing Code), and the condition precedent of obtaining a loan is mandatory in case of credit financing.
What subblink offers
A timeline of obligations extracted from the sale agreement text (dates, conditions, parties), to be cross-checked with the transaction file.

FAQ: leases and real estate contracts
How do I know if my lease is commercial or residential?
A commercial lease concerns premises intended for a commercial, industrial or craft activity, with a specific protective statute. A residential lease concerns housing used for living purposes. The report identifies the type from the contract text.
Does subblink check with the land registry?
No. It analyzes the text of the submitted document. Checking with the land registry, cadastre or a notary remains essential for any real estate transaction.
Is a security deposit exceeding the legal cap automatically void?
The clause exceeding the legal cap is generally reducible or unenforceable beyond the authorized maximum, but the precise consequences depend on the jurisdiction and context — worth having checked in case of a dispute.
Does subblink cover Belgian or Dutch commercial leases?
The engine applies the general legal framework identified for the contract's jurisdiction. See also the library of official contract references for templates published by authorities in several European countries.
Conclusion
Residential or commercial, a lease commits you over several years. A notice-period clause, a security-deposit cap or a poorly understood condition precedent are often paid for well after signing.
