Lease Contract Expiration Response Coach

Derivation Chain

Step 1 Public administration and land management data

→

Step 2 Lack of information for tenants in their 50s on contract renewal and expiration response

→

Step 3 Simulation of renewal request right and deposit return scenarios based on user's contract conditions

→

Step 4 Generation of legal procedure timeline for deposit non-return

Problem

Tenants in their 50s must decide whether to exercise the renewal request right, the limit on deposit increases, and the process for returning the deposit when the lease expires, but it is difficult to accurately understand the complex regulations after the implementation of the three lease laws. In particular, cases such as 'when the renewal request right has already been used once vs. not used', 'how to respond when the landlord refuses renewal due to actual residence requirements', and 'the procedure for a lease registration order when the deposit is not returned on time' are difficult to judge without legal consultation (300,000-500,000 KRW / $225-$375).

Solution

By entering the contract start date, deposit/monthly rent, renewal request right usage history, and current situation (wish to renew / planning to move / deposit not returned) on the web, the service provides: (1) a comparison of legal rights and option scenarios tailored to the user's situation, (2) a timeline of actions to take before expiration (e.g., date to send a content certification, confirmation of fixed date), and (3) a step-by-step guide for procedures when the deposit is not returned, such as lease registration order → payment order → small claims court.

Target: Tenants aged 45-60 with a Jeonse (lease deposit) of 100 million KRW ($75,000) or more or semi-Jeonse, within 6 months of lease expiration, who lack legal knowledge but want to handle matters directly.

Revenue Model: Basic scenario analysis: Free. Premium: Custom content certification draft generation (5,000 KRW / $3.75 per transaction), step-by-step legal procedure checklist + notifications (3,000 KRW / $2.25 per month), referral fee for connecting with law firms.
