Before You Buy

The most common problems with land in Portugal.

Registered area differs from the real area

The registry or tax record says one thing, the land measures another. It changes the price you should pay and can block the deed.

Boundaries that do not match the Cadastro

Neighbours, fences and the official boundaries rarely agree. Undocumented limits become disputes after you buy.

No legal access to the land

A path you can walk is not always a registered right of way (serventia). Without it, building or even entering can be contested.

Part of the land in REN or RAN

Ecological and agricultural reserves can remove most of the building area, and it is easy to miss without the official maps.

Rustic land sold as buildable

Being advertised as buildable is not the same as being buildable under the PDM. The regulation decides, not the listing.

Ruins and buildings without a licence

An old ruin can look like a building right, but without valid documents it may be worth much less than the seller says.

How It Works

Simple. Transparent. Thorough.

Founder, SGA Secure Ground Advisory

I didn't take the traditional route. At 18 I was working in a logistics warehouse. At 20 I walked into a real estate agency in Sintra and began what became a decade in Portuguese real estate. Sintra is one of the country's largest and most complex municipalities: properties without licences, wrong registered areas, undocumented boundaries, missing rights of way. I met every kind of problem and learned how to solve it. I worked at one of Portugal's largest real estate agencies, then at the largest in the country, and in 2023 I was invited to lead a team at one of its largest real estate groups.

What I kept seeing was a gap nobody was filling. Agents focus on closing the sale and lawyers handle the legal formalities, but the technical analysis (zoning, cadastral checks, building potential, hidden liabilities) kept falling through the cracks. SGA exists to close that gap. I'm not here to replace your lawyer or your agent. I'm here to make sure you know exactly what you are buying, before you commit.
