Due Diligence in Costa Rica
A buyer-focused guide to the legal, physical, and practical checks that should happen before purchasing Costa Rica real estate.

Why due diligence matters
Due diligence is the period when buyers verify that a property is legally transferable, physically suitable, and aligned with their goals. It is where assumptions are tested before the closing becomes final.
Costa Rica real estate requires careful review because property information is not always standardized. Legal access, water availability, zoning, title history, boundaries, construction quality, and maintenance realities should be confirmed before moving forward.
Legal review
A qualified attorney or notary should review the property title, ownership structure, liens, annotations, easements, survey plan, municipal status, taxes, and any corporate documents if the seller is a corporation.
The legal review should also confirm whether the property is titled, concession, maritime zone, condominium, or held under another structure. Each category has its own rules and risks.
- Confirm seller authority and ownership.
- Check liens, mortgages, annotations, and restrictions.
- Review the survey plan and registered boundaries.
- Verify municipal taxes and closing requirements.
Physical and infrastructure review
The physical review should look beyond the visible home or lot. Access roads, drainage, slopes, retaining walls, water source, electric service, internet options, septic systems, and nearby development can all affect long-term enjoyment and resale.
For raw land, buyers should confirm buildability, water availability, setbacks, zoning, soil or slope concerns, and practical construction logistics. For homes, inspections can uncover maintenance items that should be understood before closing.
Using the findings
The goal of due diligence is not to make every property perfect. The goal is to understand the facts clearly enough to decide whether to proceed, renegotiate, request repairs, extend review time, or walk away.
A good process keeps the buyer informed at every step and documents the main findings so the purchase decision is based on evidence, not pressure.
