Mark D’Alelio is a recognized authority on company law in Thailand, bringing over two decades of cross-border experience with a commercial focus on foreign direct investment, real estate, projects & dispute resolution. As a partner at Blumenthal Richter Sumet & Schuler (BRS&S), he advises multinational investors, regional operators and Thai corporates on complex corporate structuring, market entry and regulatory compliance matters. His practice is routinely engaged where company law intersects with investment incentives, land rights and contentious enforcement issues, making him a go-to company lawyer in Thailand for clients seeking pragmatic, locally attuned advice.
D’Alelio joined BRS&S following the integration of his Bangkok-based practice, Legal ASEAN, into the firm, bringing a team that strengthened BRS&S’s regional capabilities across ASEAN. During his career he has practised in Thailand, Vietnam and Myanmar and has advised on market entry, joint ventures, BOI promoted structures and hospitality sector projects, among other corporate matters. D’Alelio’s hands-on transactional work and dispute management define his approach, and his leadership role at Legal ASEAN and subsequent partnership at BRS&S are well documented in firm communications.
D’Alelio’s corporate practice is anchored in company formation, shareholder agreements, foreign ownership workarounds, BOI promotion applications, corporate governance and regulatory compliance. He regularly structures investment vehicles for international technology & IT sector entrants, negotiates management and development agreements for hotel and resort clients, and advises on governance matters for both private limited companies and public companies preparing for market activity. His litigation and administrative experience particularly in land, labour and commercial disputes enables him to assess risk, mitigate disputes before they crystallize and manage enforcement or regulatory proceedings when they do.
D’Alelio serves a range of sectors with particular emphasis on real estate & hospitality, technology & IT, and cross border investments into CLMV markets (Cambodia, Lao PDR, Myanmar, Vietnam). What distinguishes his approach is the combination of regional, on the ground experience with a practical, business first orientation: rather than only producing legal opinions, his team structures implementable arrangements that account for Thai land law, foreign ownership limits and the BOI regime. That pragmatic focus is frequently sought by international investors navigating Thailand’s sectoral restrictions and procedural intricacies.
Publicly reported firm and press material record D’Alelio’s role in strengthening BRS&S’s regional offering through the acquisition of Legal ASEAN and his involvement in cross border FDI mandates and hotel management negotiations. He has advised on BOI applications and market entry strategies for technology and service businesses, and has led teams managing real estate disputes and administrative proceedings. In addition to transactional work, D’Alelio has contributed to regional legal commentary and client facing thought leadership on practical issues for foreign investors in Southeast Asia.
Company law in Thailand is shaped by multiple overlapping regimes: the Civil & Commercial Code, the Foreign Business Act (FBA) and incentive frameworks administered by the Board of Investment (BOI). Foreign ownership restrictions under the FBA and sectoral licensing rules mean that otherwise straightforward company formations can require tailored structures, BOI promotion or specific licences to secure operations and land rights. The BOI offers substantive tax & non-tax privileges and, in certain promoted activities, can remove ordinary foreign ownership limits but securing and managing those privileges requires detailed procedural compliance and careful alignment with corporate governance. For investors and Thai counterparties alike, specialist guidance from an experienced company lawyer in Thailand is essential to avoid regulatory pitfalls and to preserve transactional value.
D’Alelio adopts a pragmatic, commercially focused methodology: he begins by identifying regulatory and operational risk drivers, then aligns corporate structures, documentation and governance controls to client objectives. He places particular emphasis on clear contractual allocation of risk in management and development agreements, on meticulous due diligence for land and title matters, and on proactive regulatory engagement for BOI or foreign business licensing where required. Clients value D’Alelio’s regional experience and the continuity he provides from initial market entry through to project implementation and dispute resolution.
D’Alelio’s clients include overseas investors entering Thailand for the first time, multinational groups expanding their ASEAN footprint, Thai developers and hospitality operators, and technology companies seeking to structure local operations under local rules. Businesses confronting ownership ceilings, complex land arrangements, BOI incentive strategies or cross border contractual risk will find his combination of transactional, regulatory and contentious experience particularly beneficial. D’Alelio’s commercially sensible legal solutions, tailored to local realities, make his advice accessible to non‑legal decision makers as well as in-house counsel.

Contract practice in Thailand requires careful navigation of a hybrid legal environment where Civil and Commercial Code principles interact with sectoral regulations, land and foreign ownership restrictions, and administrative licensing regimes. Key challenges include ensuring enforceability of foreign-law governed clauses, structuring around foreign ownership limits, dealing with land title complexities and aligning commercial agreements with Board of Investment (BOI) incentives where applicable. Specialist advice significantly reduces transactional risk and helps international parties anticipate regulatory roadblocks.
For cross border contracts, practitioners must also address choice of law, jurisdiction and arbitration provisions, the practicalities of enforcing judgments or awards in Thailand, and the operational impacts of labour and tax considerations on contractual commitments.
