Are They Allowed to Do That?
It's not always easy to assess what's legal in a rental agreement.
This Way, Not That Way.
Just because it's in the contract doesn't make it law.
We highlight passages that are not legally valid, so you know where you can say «Yes» but are allowed to mean «No».
Safe, Critical, Clarify.
We translate paragraphs into action recommendations. You won't receive an incomprehensible treatise, but a clear assessment: What's safe, what's critical, what do you need to clarify?
Even If It's Written There.
Contracts cannot override the law. You don't have to comply with invalid clauses, no matter what the landlord demands.
What to Expect in Your Report.
Concrete Action Recommendations
Should you contact the landlord before signing? Or is it safe to sign because the clause is invalid anyway?
Ineffective Clauses
We show you clauses that are in the contract but are often legally ineffective. You don't have to challenge them immediately. It's enough to know that you can ignore them in case of emergency.
Simple Language Explanations
You'll receive a clear summary in understandable language. This way, you'll know exactly where you stand.
