What Is Subletting: Legal Definitions and Issues
Subletting (or subleasing) refers to a tenant renting out a property to another person without the landlord's permission. In legal terminology, this is called "subletting" or "breach of trust subleasing." While it might seem like a simple matter of "renting a room to someone and collecting rent," under Japanese law, unauthorized subletting without the landlord's consent is a serious violation, and in the worst case, you could face legal action. This is especially important to understand if you're in a share house or room rental situation where you might become the "lessor" yourself. Understanding these legal risks is essential.
