Methodology, limitations and corrections

01

Method and firm selection

Firms were selected through a purposive, lead-based search for Thai legal-service websites addressing foreign property ownership, Thai company formation, company-held land, Thai shareholders, preference shares, voting control, nominees or related arrangements. Priority was given to firms that appeared to remain active and had usable Internet Archive coverage.

The sample also includes firms whose archived material rejected nominees or promoted compliant alternatives, providing control results against which stronger wording can be evaluated. The expanded project aims to identify at least 100 organizations with material Grade-A or Grade-B historical wording while retaining every relevant Grade-C control and Grade-D inconclusive result encountered. The resulting total may substantially exceed 100 organizations.

This is a purposive, lead-based study—not a random, comprehensive or statistically representative sample of Thai law firms. Inclusion in the candidate ledger indicates only that an organization was identified for topic screening; it is not an evidence grade and does not imply misconduct.

The latest regional reevaluation deliberately reduces the earlier Bangkok concentration by emphasizing Chiang Mai, Hua Hin and the Prachuap Khiri Khan corridor, Rayong, Chonburi outside Pattaya, Krabi, Phang Nga, Surat Thani and other regional foreign-property markets. Regional directory or consular-list inclusion remains a discovery lead only.

Expanded-review status, 20 August 2026: 237 candidate organizations; 192 identified current websites across 191 unique domains; 45 unresolved-domain leads; 101 completed archive inventories; 89 archive queries awaiting retry; one identified domain awaiting its first inventory; and 202 privately retained pages undergoing contextual review. Publication review has produced 15 completed firm profiles supported by 28 vetted archived webpages. A firm profile may cite more than one webpage. Directory inclusion, a retry state and research-progress counts are not findings or evidence grades.

The Internet Archive CDX index was queried for historical URLs associated with each target. Relevant captures were reviewed as complete pages where possible, compared across dates, and recorded with direct timestamped archive links. Searches focused on land ownership, property purchasing, Thai companies, nominees, trustees, preference shares, voting rights and foreign control.

Evidence grades

Separate continuity classification

Evidence grades classify archived wording only. A separate continuity field records whether a historical domain appears active at the same address, migrated to a documented new domain, was renamed or rebranded, appears defunct, or remains unresolved. Similar names, branding, contact details or text are treated as leads rather than proof of legal-entity continuity.

03

Limitations

A capture proves that content appeared at an archived URL on a capture date. It does not necessarily establish the original publication date, author, legal accuracy, transaction history or present ownership of the domain.

It also does not establish that the historical website operator and a present-day firm using the same name, brand or domain are the same legal entity. Some captures omit styling, images, scripts or linked documents. A failed replay does not prove that a page never existed.

04

Publication controls

Use precise verbs: an archived page “stated,” “offered” or “described” a structure. Saying a firm carried out an unlawful transaction requires independent evidence. Firm names are used solely to identify and organize archived source material.

All classifications and summaries are provisional research assessments of historical website language—not judicial findings, regulatory determinations or allegations that unlawful services were provided.

CDX files preserve the Internet Archive index response used during review. The index can contain duplicate rows for a capture; these are retained rather than silently rewritten. The public metadata file records the SHA-256 checksum shown on each source-record page.

05

Corrections and firm responses

This project welcomes documentary corrections, clarifications and responses from named firms and other affected parties. A submission should identify the specific statement at issue and provide supporting documents or links.

Verified factual errors will be corrected promptly and recorded with the date and nature of the correction. Relevant responses may be published alongside the research, clearly identified as responses from the submitting party. Publication of a response does not imply agreement or disagreement with its contents.

Suggest a missing site

Do you know a relevant Thai legal-services website that does not appear in the research ledger? Email the organization’s name, location and current or historical URL. Relevant, distinct sites will be added as unreviewed research leads after basic identity and duplicate checks. A suggestion or listing does not imply misconduct, and no evidence grade is assigned until archived material has undergone page-level review.
