The Problem Nobody Talks About

You find the perfect property in Spain.

Beautiful pool. ✓ Extended terrace. ✓ Extra guest room. ✓ Outdoor kitchen. ✓ Amazing sea views. ✓

You visit once.
You fall in love.
You pay a reservation deposit.

And only later do you discover something most buyers never expect:

Part of what you thought you were buying… may not legally exist.

This is one of the biggest shocks for foreign buyers in Spain.

Because in many countries, people assume:
“If it is built, it must be legal.”

In Spain, that assumption can become very expensive.

The problem nobody talks about

We regularly see properties where:

• extensions were built without permission,
• pools were never declared,
• terraces were enclosed illegally,
• garages became bedrooms,
• guest apartments were added years later,
• or the property simply does not match the Land Registry or Cadastre records.

And the dangerous part?

Sometimes even the seller does not fully understand the situation.

The property may have been bought and sold multiple times like this.

But that does not automatically make everything legal.

“But the house is already registered…”

This is where many buyers get confused.

A property can:

• physically exist,
• appear in the Land Registry,
• have a tax bill,
• have electricity and water,
• and still contain legal or urban planning issues.

Registration alone does not always mean the entire property complies with planning regulations.

That distinction matters.

Especially if one day you want to:

• sell,
• renovate,
• apply for a tourist licence,
• refinance,
• or pass the property to your children.

The real risk

The real problem is not usually that the police suddenly arrive to demolish a terrace.

The real problem is this:

You discover the issue at the worst possible moment.

Usually:

• when you try to sell,
• when the buyer’s lawyer checks the paperwork,
• when applying for a mortgage,
• or when you need legalisation documents urgently.

And suddenly a “small issue” becomes:

• delays,
• stress,
• unexpected costs,
• negotiation problems,
• or even a lost sale.

This is why legal due diligence matters

A good legal check is not about creating fear.

It is about understanding exactly what you are buying before committing your money.

At SGM Abogados, we do not just check who owns the property.

We analyse:

• Land Registry information,
• Cadastre discrepancies,
• possible undeclared extensions,
• planning risks,
• debts and charges,
• licence issues,
• and whether what physically exists matches the legal documentation.

Because buying safely in Spain is not just about signing at the notary.

It is about understanding the property before you become responsible for its problems.

Final thought

Spain offers incredible opportunities to buy property.

But buyers who rely only on appearances often discover problems too late.

And in Spanish property law, what you see is not always what you legally own.

That is why proper legal advice before paying a deposit is not an extra cost.

It is protection.
