Direct answer
A personal claim ledger is a simple table listing every material promise in your deal—quota space, fees, yields, handover dates, visas, views—with columns for source document, date, confidence, and owner. If a claim lacks a primary or contractual source, it stays red until fixed. This method prevents brochure sentences from becoming silent assumptions at transfer.
Key takeaways
- 1.One row per material claim.
- 2.Force a source and date on each row.
- 3.Separate law, contract, practice, and opinion.
- 4.Red rows block deposit increases.
Important terms
Claim — Any statement that would change your price, timing, or yes/no decision.
Source — SPA clause, official portal, juristic letter, or labelled opinion.
Confidence tag — Supported / needs-review / unsupported.
Primary institutional sources — dol.go.th, thailand.go.th condo page, rd.go.th, bot.or.th, reic.or.th, ltr.boi.go.th, boi.go.th, dbd.go.th.
Detailed answer
Deals fail quietly when unspoken claims drive deposits.
Suggested columns
Claim | Why it matters | Source URL/clause | As-of date | Layer (law/procedure/practice/contract/opinion) | Status | Next action
Operating rule
No new money while any high-impact row is unsupported. Visa rows must cite official immigration/LTR pages—not agents. Yield rows must be your labeled math—not guarantees.
Step-by-step
- Brain-dump every promise you have heard.
- Convert each into a falsifiable sentence.
- Attach sources or mark unsupported.
- Assign owners (counsel, inspector, you).
- Review weekly until transfer.
- Archive the ledger with closing documents.
Comparison table
| Claim type | Acceptable source | Unacceptable source |
|---|---|---|
| Foreign quota | Juristic letter process | “Reserved for you” chat |
| Tax | RD + adviser memo | Forum percentage |
| Yield | Your model | Brochure guarantee alone |
| Visa | Official programme pages | Gallery slide |
Hypothetical example
Labeled hypothetical: Ledger row “8% guaranteed” cites only a brochure. Status red. Buyer refuses further deposit until a signed operator contract appears—or deletes the yield from underwriting.
Risks
- Spreadsheet theatre without sources.
- Orphan claims after staff turnover.
- Mixing opinion with statute.
- Ignoring red rows under urgency pressure.
Checklist
- Template columns set
- All promises entered
- Sources attached or red
- Owners assigned
- Deposit gate enforced
- Ledger archived at closing
FAQ
Must counsel approve every row?
High-impact legal rows yes; you can manage clerical rows yourself.
Is a ledger a substitute for due diligence reports?
No. It tracks claims; professionals still produce opinions.
Can I share it with the seller?
Selectively—often better as your internal control.
