Texas Rule 106 Explained: A Practical Guide to Substitute Service in Texas

Texas Rule 106 Explained: When a defendant evades service, refuses to answer the door, or cannot be personally served after several attempts, Texas Rule 106 provides a possible remedy.
If a defendant avoids service, refuses to answer the door, or cannot be personally served after multiple attempts, Texas Rule 106 may provide a solution.
Texas Rule 106 is a key provision of the Texas Rules of Civil Procedure, allowing courts to authorize alternative service methods when traditional attempts have failed.
Understanding Rule 106 helps attorneys, paralegals, collection agencies, businesses, and legal support staff prevent delays, reduce litigation costs, and maintain case progress.
This guide explains how Texas Rule 106 operates, when substitute service may be authorized, the evidence courts usually require, and how professional process servers help demonstrate due diligence.
Below is a step-by-step outline of how to request substitute service under Texas Rule 106:
  1.  Attempt personal service multiple times at different times of day and on different days.
  2. Carefully document each service attempt with dates, times, property observations, and other relevant notes.
  3. Gather supporting evidence, such as photographs, notes, and any communications with neighbors or building staff.
  4. Prepare and file a Motion for Substitute Service with the court, including detailed affidavits from the process server describing all attempts at personal service and supporting documentation.
  5. Propose one or more alternative methods of service that are reasonably likely to notify the defendant (e.g., posting, delivery to another resident, or electronic service).
  6. Await court review. If the judge is satisfied that due diligence has been exercised, the order for substitute service will be issued, specifying the method to be used.
  7. Complete service as directed and file proof of substitute service with the court.

What Is Texas Rule 106?

Texas Rule 106 governs how legal documents may be served on a defendant.
The rule permits service through:
  • Personal delivery
  • Certified mail
  • Court-approved substitute service
Most lawsuits start with traditional service attempts. If these fail, a party may request court approval to use an alternative method.
This request is known as a Motion for Substitute Service.

Texas Rule 106 Service Methods Comparison

Personal Service No Standard service of process Strongest proof of service
Certified Mail No Cooperative defendants or businesses Cost-effective
Substitute Service Yes Defendant avoids service Prevents delays
Door Posting Yes Evasive defendants Effective when occupancy is confirmed
Email Service Yes Verified communication exists Fast and trackable
Alternative Court-Approved Method Yes Unique circumstances Flexible solution

Why Rule 106 Matters

Defendants may not always cooperate.
A defendant may:
  • Refuse to answer the door.
  • Ignore repeated service attempts.
  • Move without modifying records.
  • Live in a gated community.
  • Restrict access to a workplace.
  • Intentionally evade service
Without Rule 106, judicial processes might face indefinite delays.
Rule 106 ensures defendants cannot avoid legal action by declining service, providing courts with a workable solution.

What Is Substitute Service?

Substitute service is a court-authorized method for delivering legal documents when personal service is unsuccessful.
After reviewing evidence of diligent attempts to serve, a judge may authorize alternative methods reasonably likely to provide notice to the defendant.
Examples include:
  • Leaving documents with another resident
  • Posting documents on the front door
  • Affixing documents to the main entrance
  • Service by email
  • Service through electronic means
  • Other court-approved methods
The method authorized depends on the facts of the case and the court’s discretion. Additionally, some Texas counties or judges may have specific preferences or additional requirements regarding substitute service. Attorneys should be aware of local rules and be prepared to address county-specific nuances when seeking court approval.

What Evidence Is Required?

Courts generally expect evidence that traditional service methods were diligently attempted before requesting substitute service.
Professional process servers often provide:

Multiple Service Attempts

Attempts made at various times, including:
  • Morning
  • Afternoon
  • Evening
  • Weekend
This demonstrates a genuine effort to locate the defendant.

Detailed Field Notes

The process server documents:
  • Date and time of each attempt
  • Property observations
  • Vehicles available
  • Signs of occupancy
  • Conversations with neighbors
  • Access restrictions

Photographs

Photos may help demonstrate:
  • Residence verification
  • Occupancy indicators
  • Gated community restrictions
  • Posted notices

Locate Service Research

If a defendant appears to have moved, locate service research may help identify a current address before requesting substitute service.

Evidence That Supports a Rule 106 Motion

Multiple Service Attempts Demonstrates due diligence
Different Days and Times Shows reasonable effort
Photographs Verifies occupancy and location
Vehicle Information Helps establish residency
Property Observations Supports affidavit statements
Witness Statements May confirm residency
Locate Service Results Identifies current addresses
Detailed Affidavit Provides evidence for the court

How Many Attempts Are Required?

Texas Rule 106 does not specify a minimum number of service attempts.
However, courts generally expect evidence showing reasonable diligence.
Many attorneys prefer three to six well-documented attempts before filing a Motion for Substitute Service. This range is supported by guidance from local administrative rules and best practices, such as the Texas Pattern Jury Charges and Harris County court standing orders, which often require at least three diligent attempts. Additionally, Texas courts have cited this range in decisions such as In re E.R., 385 S.W.3d 552 (Tex. 2012), emphasizing that multiple good-faith attempts help demonstrate reasonable diligence.
Quality matters more than quantity.
Five attempts conducted at different times are often more persuasive than numerous attempts made under identical conditions.

Common Reasons Courts Grant Substitute Service

Courts may authorize substitute service when evidence demonstrates:
  • The defendant is actively evading service.
  • The defendant resides at the address but refuses contact.
  • Personal service has repeatedly failed.
  • Standard methods are impractical.
  • Alternative methods are likely to provide notice.
Each case is evaluated individually.
The stronger the documentation, the stronger the motion.

Common Reasons Substitute Service Is Granted

Defendant refuses to answer door High
Defendant hides inside residence High
Defendant observed but avoids contact High
Gated community blocks access Moderate to High
Workplace restrictions prevent service Moderate
Defendant moved from address Low until current address is verified
Only one service attempt made Low
Poor documentation Low

Rule 106 and Evasive Defendants

Evasive defendants are common in:
  • Debt collection lawsuits
  • Business litigation
  • Contract disputes
  • Family law matters
  • Property disputes
Experienced process servers regularly encounter tactics such as:
  • Turning off lights when service is attempted
  • Watching through windows without answering
  • Directing family members to deny residency
  • Leaving through alternate exits
  • Refusing to identify themselves
Detailed documentation can greatly strengthen a substitute service request.

Can Service Be Posted on the Door?

Possibly.
If a court finds that posting service on the front door is reasonably likely to provide notice, the judge may authorize that method.
However, posting generally requires a court order.
Attorneys should not assume posting is automatically permitted without judicial approval.

Can Email Service Be Authorized?

In some circumstances, yes.
Texas courts have increasingly considered electronic service methods when supported by sufficient evidence. To authenticate an email address or other electronic means for service, courts typically require evidence such as prior communications with the defendant through that email, verification that the account is actively used by the defendant, confirmation from business records, or sworn affidavits detailing the connection between the address and the party to be served. Attorneys should be prepared to submit documentation that establishes both regular use and the reliability of the electronic contact information.
Relevant factors may include:
  • Verified email addresses
  • Former communication history
  • Business records
  • Evidence showing regular account usage
Courts evaluate whether the proposed method is reasonably likely to provide actual notice.
