Google has documented a new asset type for responsive search ads called the text disclaimer, a standalone field of up to 90 characters that carries legal or compliance wording without consuming a description line. The details sit in Google's Google Ads Help Center documentation, which carries no publication date, so the accurate framing is that Google has documented it, not that it launched on a particular day.
The appeal for regulated advertisers is direct. An account in finance, insurance or clinical services that repeats mandatory wording in every ad spends a description line on it, and a dedicated disclaimer gives that line back. One documented behaviour will catch anyone who pins, though.
What Google's documentation says a text disclaimer asset is
Google's Google Ads Help Center documentation describes text disclaimers as a distinct asset type for responsive search ads, sitting apart from headlines and descriptions. Google's wording on length is "The character limit for a disclaimer asset is limited to 90." That matches a standard description line, context Google does not supply itself.
Order of operations matters. Google states that "Disclaimer assets can only be created after your Responsive Search Ad has been created." The documented path is Assets, the plus button, Text Disclaimer, select campaigns, enter the text and save.
The pin override is the line to read twice
Google's documentation says of disclaimer assets that "They will always override any existing pinned description line 1 assets in the campaign." In plain terms, an approved disclaimer suppresses whatever you pinned to description line 1 in that campaign.
That is the trap, because pinning description line 1 is how many regulated accounts already force compliance wording to appear. Adding a disclaimer to a campaign that pins does not stack the two messages. The disclaimer wins. If that pin exists for another reason, a price or a required brand phrase, check what it is doing first.
A disapproved disclaimer does not take the ad down
Google addresses the failure case explicitly: "If a disclaimer asset is disapproved during policy reviews, your responsive search ad will continue to serve. Other description lines or a description line pinned to position 1 will serve instead." The ad keeps running, which makes this quieter than a stopped ad: the wording you intended to show may not be showing. Put disclaimer approval status on a routine check.
Google's availability wording is future tense
The sentence Google published is "Text disclaimers will be available to all advertisers globally." Google wrote will be, not is, and the documentation carries no rollout date, no percentage and no market list. Any claim that text disclaimers are live everywhere today goes beyond Google's own text.
AI Max compatibility and the truncation caveat
On automation, Google states that "Text disclaimers are fully compatible with AI Max features, including the Final URL Expansion setting", so AI Max advertisers do not have to choose between the automation and the compliance asset.
On rendering, Google warns that "Disclaimer assets may, on rare occasions, be truncated when shown to users, especially in certain languages, or when larger font sizes are used for accessibility." Google does not name the languages. It does not name Thai and does not rule Thai out, so nothing can be claimed either way. Treat 90 characters as a working ceiling rather than a guaranteed display, which makes this a content problem as much as a settings one.
The documented behaviour against Google's wording:
| Behaviour | What Google's documentation states |
|---|---|
| Character limit | "The character limit for a disclaimer asset is limited to 90." |
| Availability | "Text disclaimers will be available to all advertisers globally." Future tense, no date or market list. |
| Pinned description line 1 | Disclaimers "will always override any existing pinned description line 1 assets in the campaign." |
| Disclaimer disapproved | The responsive search ad "will continue to serve." Other description lines, or one pinned to position 1, serve instead. |
| AI Max | "Text disclaimers are fully compatible with AI Max features, including the Final URL Expansion setting." |
| Truncation | Disclaimers "may, on rare occasions, be truncated", especially in certain languages or at larger accessibility font sizes. No language named. |
What this means for Thai marketers
Google's documentation does not mention Thailand and says nothing about any country's regulatory requirements, so none of this is Google guidance on Thai law. Generally, regulated categories carry mandatory wording, and wherever that wording occupies a description line, a disclaimer asset hands the line back to selling.
What follows is reasoning rather than anything Google stated. Thai is not written in Latin script, and 90 characters of Thai carries a different quantity of information from 90 characters of English. Since Google flags truncation "especially in certain languages" without listing any, previewing how the Thai wording renders is the cautious first step. And if compliance text is pinned to description line 1 in a Google Ads account, the override behaviour above decides which words a searcher sees.
Common questions about text disclaimer assets
Are text disclaimer assets available in my account today?
Google's documentation does not say. It states that text disclaimers "will be available to all advertisers globally", in the future tense, with no date and no market list attached. Open the Assets menu and look for the Text Disclaimer option.
Will a text disclaimer replace the description line I pinned?
Yes. Google states that disclaimers "will always override any existing pinned description line 1 assets in the campaign", so an approved disclaimer suppresses that pin campaign-wide. Audit existing pins first.
What happens if the disclaimer is disapproved?
The responsive search ad keeps serving. Google states that other description lines, or one pinned to position 1, will serve instead. Because the ad does not stop, a disapproved disclaimer will not announce itself in performance data.
Does Google say whether Thai text gets truncated?
No. Google says truncation may happen "on rare occasions", especially in certain languages or when larger accessibility font sizes are used, but the documentation names no language at all. Thai is neither listed nor excluded.
Do disclaimers work with AI Max campaigns?
Yes. Google states that text disclaimers are "fully compatible with AI Max features, including the Final URL Expansion setting", and describes no extra configuration for them.
What to do next
The work is small and mostly diagnostic. List the campaigns where compliance wording sits inside a description line, note which of them pin description line 1, then decide whether reclaiming the line is worth changing what that pin does. Google's write-up sits in its Google Ads Help Center documentation. If paid search and SEO share the same approved legal wording, align both at once.
