Problem

For tenants in their 50s-60s, the process of getting their deposit back when a Jeonse lease expires is complex and lengthy. Each step—sending a content-certified document, registering a lease right, filing a claim with a guarantee insurance, and legal procedures—has different deadlines and required documents. Missing any one step can delay the return of the deposit by several months. Lawyer consultation costs 100,000-300,000 KRW (approx. $75-$225) per case, and the Legal Aid Corporation has a waiting period of 2-3 months.

Solution

On the web, users input the lease expiration date and current situation (landlord refusal to return, loss of contact, whether deposit guarantee insurance is in place, etc.), and the service shows a step-by-step roadmap to getting the deposit back. It provides specific guidance on required documents, deadlines, application methods, and costs for each step, along with notifications for next actions.

Target: Ages 45-60, living on Jeonse, deposit of 100 million KRW (approx. $75,000) or more, lease expiring within 6 months or currently experiencing delayed return.
Revenue Model: Free basic roadmap. Premium (automatic generation of step-by-step document templates + draft of content-certified document + legal consultation connection) at 19,900 KRW (approx. $15) per transaction.
