What the Texas Certificate of Last Known Mailing Address Is

The Texas Certificate of Last Known Mailing Address documents a person's most recent mailing address for purposes such as legal notice, tax correspondence, or service of process. It records the address a party last used for official mailings and often accompanies filings, notices, or account updates where proof of the last known address is required by a government agency, court, or business. The certificate focuses narrowly on mailing address information and who provided it; it is not a transfer deed, proof of residency, or proof of identity by itself.
