Stop Property Fraud in Nigeria's Real Estate Market

Property fraud is one of Nigeria's most damaging consumer crimes. Fraudsters obtain or forge Certificates of Occupancy, sell plots they do not own to multiple buyers simultaneously, and impersonate landowners with fabricated documentation. Land registry records are not publicly accessible in most states, title searches are slow and unreliable, and buyers — particularly those buying from individuals rather than developers — have no practical protection. Your challenge is to design a property fraud prevention system for Nigerian real estate transactions that enables buyers to verify title before purchase, flags properties with multiple active sale processes, and creates a searchable record of transactions that can identify patterns of fraudulent dealing. Submit a system design document (max 12 pages) including: the title verification process and data source integration, the multiple-sale detection mechanism, how buyers access the system, the data governance and privacy model, how fraud patterns are escalated to law enforcement, and a plan to cover Lagos and Abuja property markets within 18 months. Judging criteria: 40% title verification credibility and land registry integration, 30% fraud detection design, 20% buyer access and experience, 10% law enforcement escalation model.
