DearCustomer- If you are talking about court papers you can contact the clerk of courts and simply ask if the paperwork was served. Each court keeps a docket of each case and it should show the status of the case and whether the documents have been served.
Surveillance: You can provide surveillance footage showing you were not served at the alleged date or that the service was improper. Mail Records: If there's no mail delivered to you or if you haven't signed the receipt. It can indicate improper service.
Service of Notice or "serve" means personal delivery or delivery postage prepaid via regular United States Postal Service mail.
Texas Rule of Civil Procedure 106, the procedural rule that governs service, now provides that a Court may, in proper circumstances, permit service of citation electronically by social media, email, or other technology.
