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

Texas Rule 106 Explained: When a defendant avoids service, refuses to answer the door, or cannot be personally served despite multiple attempts, Texas Rule 106 may provide a solution.

When a defendant avoids service, refuses to answer the door, or cannot be personally served despite multiple attempts, Texas Rule 106 may provide a solution.

Texas Rule 106 is one of the most important provisions of the Texas Rules of Civil Procedure because it allows courts to authorize alternative methods of service when traditional service attempts have been unsuccessful.

For attorneys, paralegals, collection agencies, businesses, and legal support staff, understanding Rule 106 can help prevent delays, reduce litigation costs, and keep cases moving forward.

In this guide, we explain how Texas Rule 106 works, when substitute service may be authorized, what evidence courts typically require, and how professional process servers help establish the due diligence needed for alternative service.

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 begin with traditional service attempts. However, when those methods fail, a party may request permission from the court to use an alternative method.

This request is commonly known as a Motion for Substitute Service.

Texas Rule 106 Service Methods Comparison

Service Method Court Approval Required Typical Use Case Advantages
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 do not always cooperate.

A defendant may:

  • Refuse to answer the door
  • Ignore repeated service attempts
  • Move without updating records
  • Live in a gated community
  • Restrict access to a workplace
  • Intentionally evade service

Without Rule 106, legal proceedings could be delayed indefinitely.

Rule 106 provides courts with a practical solution to ensure defendants cannot avoid legal action simply by refusing service.

What Is Substitute Service?

Substitute service is a court-authorized method of delivering legal documents when personal service has been unsuccessful.

After reviewing evidence of diligent service attempts, a judge may authorize alternative methods reasonably calculated 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.

What Evidence Is Required?

Courts generally expect evidence showing that traditional service methods were attempted diligently before substitute service is requested.

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 present
  • 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

Evidence Type Why It Matters
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.

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
  • Traditional 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

Situation Likelihood of Court Approval
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 significantly 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.

Relevant factors may include:

  • Verified email addresses
  • Prior communication history
  • Business records
  • Evidence showing regular account usage

Courts evaluate whether the proposed method is reasonably likely to provide actual notice.
