Thailand's Business Security Act: how a villa-holding company can pledge its business or rental income, not just the land

Can a Thai property-holding company borrow against something other than the land title itself? Yes — the Business Security Act B.E. 2558 (2015), effective 2 July 2016, created a second, entirely separate collateral system alongside the Land Department's mortgage registry: a company can pledge its business as a going concern, its contractual claims (including a stream of villa rental income), its movable property, or its intellectual property, registered instead with the Business Security Registration Office at the Department of Business Development (DBD), Ministry of Commerce.

What can actually be pledged

• The business itself, as a going concern — the operating enterprise, including goodwill and its ongoing customer relationships, not just a list of physical assets.
• Receivables and contractual claims — a right to future payment, such as a villa-rental company's stream of booking income, can be pledged without needing a physical asset to hand over.
• Movable property used in the business — machinery, vehicles, furniture, inventory and raw materials, without physically surrendering them to the lender.
• Intellectual property — trademarks, patents, copyrights and similar rights.
• Immovable property, but only in a narrow case — land or buildings can be pledged under this Act, rather than as an ordinary Land Code mortgage, only where the security provider's own business is itself a real estate business; it isn't a general substitute for a mortgage on every company-held villa.
• Other categories added by ministerial regulation — perennial plants are one example the DBD has added since the Act's original passage.

A separate registry, a separate priority ladder

Unlike a mortgage, which is registered against the title deed at the local Land Office, a Business Security Agreement is registered with the DBD's own centralised, searchable database — a different government office entirely, with its own filing system. Priority between competing security interests over the same collateral follows a strict first-to-file rule: whichever agreement the DBD's system time-stamps first ranks first, regardless of which lender negotiated terms first. A due-diligence check on a company that already holds a villa should now include a DBD business-security search, not just a Land Office title search — a company's rental income or the business itself can be encumbered without anything appearing on the land title at all.

What happens on default

The Act restricts who can act as a security receiver to specific licensed institutions — banks, finance companies, credit foncier companies, insurance companies, and certain other prescribed entities; a purely offshore, unlicensed lender generally cannot hold this role directly. On default, the security receiver can take possession of the pledged collateral, manage or preserve it, and dispose of it — typically by public auction or private sale — without first having to go through a court foreclosure process of the kind that applies to an ordinary mortgage in default. Court enforcement remains available as a fallback if the debtor refuses to cooperate.

Why this matters for a 49/51 structure

For a foreign buyer using a Thai company to hold a villa, this Act creates a financing and encumbrance route that sits entirely outside the Land Code mortgage system most buyers are familiar with. A Thai co-shareholder or a joint-venture partner could, in principle, use the company's rental-income stream or the rental business itself as loan collateral without your knowledge showing up in a land-title search — reinforcing why reviewing a target company's full DBD filing history, not just its Land Office record, belongs in serious due diligence before buying into or lending against a company-held villa.

The unsettled point: leasehold rights specifically

Some practitioner sources describe a company's leasehold interest itself as directly pledgeable collateral under this Act; a more detailed law-firm analysis instead frames standalone immovable-property collateral as available only when the security provider's own business is real estate, describing the more general 'business as a going concern' and 'receivables' categories as the reliable route for a rental-villa company rather than the leasehold interest in isolation. Sources aren't fully consistent on this narrower point — confirm the specific structure with a Thai lawyer and the proposed security receiver institution rather than assuming a leasehold can always be pledged on its own.

None of this replaces conventional financing: most villa purchases still run through an ordinary mortgage or seller/developer credit. But for a company that already owns a rental operation, the Business Security Act is a real, separate legal channel for raising capital against the business itself — and, just as importantly, a real channel through which a company's assets can be quietly encumbered by others.
