Constable Service of Process in Texas Eviction Cases: The Service That Triggers the Whole Procedure

The constable’s service of citation on the tenant is the procedural step that transforms a filed eviction petition into an actual case. For DFW landlords, constable service is the procedural step where statewide rules meet local execution. Dallas County has five constable precincts, Tarrant County has eight, Collin County has four, and Denton County has six, each with its own service patterns and response times. Without proper service, the court has no jurisdiction over the tenant, the tenant has no obligation to appear, and any judgment entered is potentially void. Texas eviction service has been substantially modified by SB 38 (effective January 1, 2026), which imposes a five-business-day service window and clarifies the alternative service methods available when personal service fails. Below, we walk through what constable service requires, the methods available, the SB 38 changes, and the most common service-related defects that defeat eviction cases.

Why service matters

Service of process is the formal mechanism by which a court acquires jurisdiction over a defendant. Without proper service:

• The court has no jurisdiction over the tenant.
• The tenant has no obligation to appear.
• Any judgment entered is potentially void or voidable.
• The tenant can later collaterally attack the judgment.

Service issues are a common reason eviction cases are dismissed or judgments are vacated. Landlords should treat service as a critical procedural step, not as a routine administrative matter.

The personal service requirement

The default rule is personal service: the citation is delivered to the tenant in person by an authorized officer (constable, sheriff, or in some cases authorized process server).

Personal service requires:

• Delivery to the tenant in person at the tenant’s residence (typically the rented unit).
• Identification of the document being served as a citation in an eviction case.
• Documentation of the service in a return of service filed with the court.

Personal service is straightforward when the tenant is at the unit. It becomes difficult when the tenant is rarely at home, refuses to answer the door, or is intentionally avoiding service.

The five-business-day service window under SB 38

SB 38 imposes a strict timing requirement for citation service:

• The citation must be served within five business days after issuance.
• The five-day window is calculated by business days (excluding weekends and holidays).
• Service that occurs outside the window may be defective.

The five-day window is significantly shorter than the previous practice and creates pressure on constables to attempt service quickly. For landlords, this means:

• Filing eviction at a time when service can be promptly attempted.
• Providing the constable with accurate tenant information and tenant schedule details.
• Following up with the constable to confirm service has been attempted within the window.

Alternative service methods

When personal service is not possible within the five-business-day window, Texas allows alternative service methods:

• Posted service. Citation posted on the door of the rented unit, typically with a copy mailed to the tenant. Used when the tenant cannot be found.
• Mailed service. Citation mailed to the tenant’s last known address. Often combined with posted service.
• Service on a person of suitable age and discretion. In some cases, service can be made on another adult at the residence.

The exact procedures for alternative service vary by court and depend on case-specific factors. The landlord typically requests alternative service through a motion or a court order, depending on local practice.

For SB 38, alternative service rules have been clarified to ensure proper notice while accommodating the realities of tenant unavailability.

The return of service

After service (whether personal or alternative), the constable files a return of service with the court. The return must include:

• Date of service.
• Time of service.
• Method of service (personal, posted, mailed, etc.).
• Person served (if personal service).
• Location of service.
• Constable’s signature.

The return becomes part of the court file and is the official record of service. Defective returns can support tenant defenses to the case.

Common service defects

Several common defects can defeat eviction cases:

• Service outside the five-business-day window. Citation served on day six or later may be defective.
• Service at the wrong address. Service must be at the rented unit (or a properly designated alternative). Service at an old address may be defective.
• Improper alternative service. Posted service without complying with local procedures, or mailed service without confirmation of receipt, can be defective.
• Service on the wrong person. Service on a child, an unrelated visitor, or a person of insufficient age can be defective.
• Defective return. Returns lacking required information or with errors can support service challenges.
• Improper documentation. Failure to file the return with the court within required timeframes can be procedural.
• Service refused. The tenant who refuses service or won’t answer the door can sometimes still be properly served (through posted service or in some cases by leaving citation at the door), but the documentation must support the procedure.

The constable’s role and limitations

Constables in Texas are elected county officials with multiple responsibilities including civil process service. Their role in eviction cases:

• Receive citations from the court.
• Attempt service within the timing requirements.
• Use authorized service methods.
• Document service in returns.
• Execute writs of possession after the waiting period.

Constables vary in workload, efficiency, and procedure across Texas counties. Some constables handle large eviction volumes with established protocols; others have lighter caseloads and less standardized procedures. Landlords with high eviction volumes typically develop relationships with constables and understand the local procedures.

Service in difficult situations

• Tenant rarely home. Combination of personal service attempts and posted service. Documentation of unsuccessful attempts supports alternative service.
• Tenant intentionally avoiding service. Multiple attempts at varied times, posted service combined with mailed service, sometimes service on family members in the unit. Document the avoidance pattern.
• Tenant living elsewhere. Service at the rented unit may be sufficient if the tenant is responsible for receiving mail there, but better practice is to request alternative service to a known address.
• Tenant claiming no notice. Even properly served tenants sometimes claim they didn’t receive notice. The constable’s return is the operative record; the tenant’s later denial is generally insufficient to defeat the return.
• Service of multiple parties. When multiple tenants are on the lease, each must be served. Service on one tenant doesn’t automatically bind others.

Tenant defenses to service

Tenants can challenge service through:

• Motion to vacate default judgment based on improper service.
• Direct attack on jurisdiction.
• Bill of review (in extreme cases).

The standards for these challenges depend on the type of judgment and how long ago it was entered. Default judgments are easier to vacate than judgments after appearance.

Service defects identified before judgment can typically be cured by re-serving. Service defects identified after judgment can vacate the judgment.

When to push and when to wait

For landlords pursuing eviction:

• Provide accurate tenant information. Address, daytime hours when tenant is likely home, contact information, etc.
• Time the filing strategically. File at a time when the constable can promptly attempt service.
• Follow up promptly. If service hasn’t been completed within the window, find out why and what alternative service is appropriate.
• Document everything. The constable’s return is one piece; the landlord’s own documentation of communication with the constable, request for alternative service, etc. supports the case.
• Be prepared for re-service. If service fails, be ready to request re-service quickly to avoid case dismissal.
• Consider service issues at the strategy stage. Some properties or tenants are notorious for service difficulties. Plan accordingly.

Common service mistakes

• Filing without a service plan. Cases get filed and then forgotten about by the landlord; the constable struggles to serve and the case stalls. Landlords should follow up on service status promptly.
• Wrong tenant address. Filing eviction with an old address (e.g., the address from the original lease application) when the tenant is now at the rental unit.
• Single-attempt service. Constables typically attempt service multiple times, but sometimes a single attempt is treated as sufficient. The landlord should follow up if a single attempt fails.
• Unrelated persons. Service on visitors, contractors, or children at the property is generally not effective. The constable should distinguish.
• Skipping documentation of avoidance. If the tenant is intentionally avoiding service, documentation of the avoidance pattern supports alternative service requests.
• Late re-service requests. After failed service, the landlord should request re-service or alternative service quickly. Delay can support tenant claims of lack of notice.
