Matrimonial & Infidelity Investigations in Spain

Is your partner really on a golf trip — or something else entirely?

What happens on holiday doesn't always stay on holiday!

When someone you love heads off to Spain without you — for a “golf trip with the lads,” a “hen weekend in Marbella,” or a business trip in Ibiza — it’s normal to worry.

You’ve been here before. The messages slow down. The stories don’t line up. Suddenly, they’re “too busy” to talk. And that gut feeling you’ve tried to ignore? It won’t go away.

At Expat Investigations, we specialise in discreet surveillance of partners on holiday, across Spain’s biggest tourist and party hotspots — including Benidorm, Ibiza, Marbella, Alicante, and the Costa del Sol.

Cheating Husband on a Golf Trip to Spain

Private Detective following cheating partner in Spain

We’ve Seen It All — And So Have You

We work with people just like you every week:

Partners left behind in the UK while someone flies off “with the boys”
Husbands who’ve suddenly started locking their phones
Wives on hen weekends that last a little too long
Business trips with strange new “friends” that never existed before

Whatever your reason, we don’t judge. We just find out the truth.

How It Works

✅ Physical Surveillance

Our team follows your partner while they're abroad — in person. We document their movements, interactions, and whereabouts using covert video and photography.

✅ Full Pre-Trip Planning (if possible)

Contacting us before they go helps us help you. If you can give us:

Flight details
Hotel bookings or locations
Travel dates
— we’ll have an agent ready and waiting when they land.

✅ GPS Tracking (Pre-Departure Option)

On occasion, clients have arranged to place a GPS tracking device inside luggage or a vehicle before their partner even leaves the UK. This enables real-time 24/7 monitoring from the moment they arrive in Spain.

We’ll guide you through what’s possible — confidentially and discreetly.

We Work Where They Party

Our team operates across the most common “cheating hotspots” in Spain, including:
Benidorm • Marbella • Ibiza • Alicante • Torremolinos • Fuengirola • Magaluf • Torrevieja

And if your partner strays further inland or off the radar? We’ll follow.

Confidential. Untraceable. Discreet.

Everything we do is 100% confidential.

We never reveal your identity
We leave no digital trail
We only share our findings with you

Your peace of mind is our only goal.

We don't ask why — we just get the job done!

Want the Truth — Before or After They Land?

Can you still help if my partner is already on holiday?

Yes. While it’s helpful to plan ahead, we regularly begin surveillance after the subject has arrived. We can mobilise quickly anywhere in Spain.

What kind of evidence will I get?

We provide discreet video and photographic evidence showing the subject’s movements, interactions, and behaviours — clear, timestamped, and confidential.

Will they find out I hired you?

No. Our operations are fully covert. Your identity remains protected and there is no trace of our involvement unless you choose to disclose it.

Can you track them without them knowing?

In some situations, yes. We’ve helped clients discreetly place GPS trackers in personal items before travel. We’ll advise you on what's possible and legal.

Where do you operate?

We work across all major Spanish destinations: Benidorm, Marbella, Ibiza, Alicante, the Costa del Sol, and more. If your partner’s there — so are we.

My partner and I are LGBT — is that a problem?

Not at all. We work with all individuals and couples — no judgment, no bias. We treat every case with the same level of care, professionalism, and confidentiality.

If I supply you with pictures of my partner, what happens to them after?

Images and identifying info are used strictly for your case. Once your case is complete, we delete all materials securely. Nothing is stored, shared, or reused.
