BANGKOK, THAILAND – A 68-year-old Swiss man lost almost all his savings in Thailand within three weeks after trying to build a life with a new partner, exposing the legal risks foreigners face when investing informally.
Three weeks in Bangkok and a life-changing decision
Karl-Heinz, a 68-year-old Swiss national, arrived in Bangkok as a tourist in the summer of 2025. Two years widowed and with his children long moved out, he met Nok after three weeks in the city. She was 34, described as friendly and patient, and he paid her 1,200 baht a day, about 32 euros.
The pair travelled together to Krabi and then to her family in Buriram province in northeastern Thailand. There he decided he wanted to stay, buy land, build a house and purchase a car. He returned to Bern, dissolved his household, sold his belongings and transferred the proceeds – 6.1 million baht, around 163,000 euros – to Nok’s account, believing it would finance house construction.
Back in Thailand: the money was gone
Two months later, Karl-Heinz landed again at Suvarnabhumi Airport, where Nok picked him up. In Buriram he was told the land had already been bought and construction was under way. When he later heard there was no money left for cars, the reasons remained unclear and he did not ask further questions.
He still bought a new Toyota and a Honda motorcycle and had both vehicles registered in Nok’s name. Receiving almost 200,000 baht a month in Swiss pension payments, about 5,300 euros, gave him the feeling he could afford it. Shortly afterwards, Nok suggested moving to Pattaya until the house was finished, and he agreed.
Pattaya: when interests drift apart
In Pattaya, the couple rented an apartment. Nok went out in the evenings and returned in the mornings, while Karl-Heinz waited. Other long-term German-speaking residents he had met warned him about the situation.
He ignored their concerns, convinced his case was different from others. At the time of publication, it remained unclear whether the house would ever be completed, whether the plot actually existed or whether he would ever move in. What was clear, however, was that he had no legal claim to anything: not to the land, not to the vehicles and not to the 6.1 million baht.
Why foreigners cannot own land in Thailand
Thai law explicitly barred foreigners from owning land in their own name. Section 86 of the Thai Land Code prohibited land acquisition by foreigners without exception for private individuals, regardless of marriage, long-term visas or decades of residence. The land title stood in the Thai partner’s name; she was the legal owner.
Under Section 521 of the Thai Civil and Commercial Code, money transferred for a plot into a Thai woman’s account was legally considered a gift. A voluntary transfer without compensation counted as a donation. It could only be reclaimed under very narrow conditions, such as in cases of serious criminal acts by the recipient.
“I thought this was our house”
said no valid legal argument existed in Thailand to undo such a donation. The belief in joint ownership did not create any enforceable rights under these provisions.
Vehicles in another person’s name: the same mistake
The same legal principle applied to cars and motorcycles. Payment alone did not determine ownership; the decisive factor was whose name appeared on the vehicle registration document. Although Karl-Heinz had paid for the Toyota and Honda, the registration listed Nok as the owner.
If the relationship ended, she could drive, sell or give away both vehicles. Thai courts were not expected to side with him based on informal or verbal agreements. Without written contracts and proper registration, his financial contributions gave him no enforceable claim.
Foreigners were in fact allowed to register vehicles in their own name in Thailand. This required a valid visa, proof of residence and typically a certificate from the local registration office or from their embassy. According to the account, Karl-Heinz did not take these administrative steps.
Legal alternatives for long-term stays
Foreigners planning to live long-term in Thailand and invest in property had lawful options to secure their position. One of the best-known instruments was a usufruct right, called Usufruct in English, which could be registered at the land office. This granted the foreigner the right to live on and use the property for life, even when the title deed remained in the Thai partner’s name.
If the land was sold, the usufruct right stayed attached to the title deed rather than to the relationship. The new owner had to respect the registered right of use as long as it remained in force. This mechanism allowed some security without violating ownership restrictions for foreigners.
Another option was to purchase a condominium unit. Foreigners were allowed to buy apartments directly and fully in their own name, provided foreign ownership in the building did not exceed 49 percent. This was the only form of real estate in Thailand that foreigners could truly own outright.
What options remain for Karl-Heinz
If the land in Buriram actually existed and construction was progressing, one remaining option for Karl-Heinz would be to agree a usufruct contract with Nok and register it at the land office. This would be relatively inexpensive and would at least secure lifetime residential rights on the property.
Whether Nok would agree to such an arrangement was an open question, and her refusal would itself be a clear signal. The account recommended that anyone in a similar situation consult a lawyer licensed in Thailand, rather than relying on intermediaries or property agents.
Independent legal advice would cost only a fraction of what might otherwise be at stake. The described case was based on a real incident, with the name and some details changed to protect the individual.
The report stressed that Karl-Heinz was not portrayed as naive; he had worked all his life, raised a family and taken responsibility. What he lacked was not intelligence but information. The article concluded that Thailand’s laws were clear, and that those who understood them in advance made different decisions and could still invest – but only with contracts, with lawyers and with their own names on the documents.
Editorial notes stated that the outcome of the situation remained unresolved at the time of publication and that the legal information reflected Thai law as of April 2026, without replacing personalised legal advice.
