One of the first questions service members ask when facing charges under the Uniform Code of Military Justice is:

How long is this going to take?

The answer is not simple — because a court-martial is not a single event.

It is a structured federal criminal process that unfolds in phases:

  • Investigation

  • Charging decisions

  • Article 32 proceedings

  • Pretrial litigation

  • Trial

  • Sentencing

  • Appellate review

At National Security Law Firm, our military defense team includes several former military judges, former military prosecutors, and a former United States Attorney. We have seen court-martial timelines from every vantage point — from the prosecution table, from the bench, and from the defense side.

This guide breaks down the real-world timeline of a court-martial — not the brochure version.

For an overview of the full defense structure, start here:
👉 Court Martial Resource Hub

Phase One: Investigation — Weeks to Many Months

Most court-martial timelines begin long before charges are preferred.

Investigations may involve:

  • Army CID

  • NCIS

  • OSI

  • CGIS

  • Command-directed inquiries

  • Digital forensic analysis

  • Search authorizations

  • Witness interviews

This phase can last:

  • 30 to 60 days in straightforward cases

  • 3 to 9 months in moderate complexity cases

  • 12 months or more in sexual assault, fraud, or digital evidence cases

Investigations take longer when:

  • Phones or computers require forensic extraction

  • Multiple witnesses are involved

  • Overseas installations are implicated

  • Experts are required

Early defense intervention during this phase often shortens timelines by shaping investigative framing.

Phase Two: Preferral of Charges — Immediate to Several Weeks

Once investigators believe sufficient evidence exists, charges are preferred.

Preferral is not trial.

It is the formal accusation under the UCMJ.

After preferral:

  • The accused is served with charges

  • A convening authority evaluates the case

  • Defense counsel begins formal litigation posture

At this stage, cases may still resolve without trial.

But if the case is moving toward a General Court-Martial, the next major step is the Article 32 hearing.

Phase Three: Article 32 Hearing — Typically 30 to 90 Days After Preferral

An Article 32 preliminary hearing is required before referral to a General Court-Martial (unless waived).

This stage often occurs:

  • 30 to 60 days after preferral

  • Sometimes sooner in fast-moving commands

  • Sometimes later if discovery is incomplete

Article 32 is a critical pressure point.

Strategic litigation here can:

  • Lock in testimony

  • Expose investigative weaknesses

  • Influence referral decisions

  • Narrow charges

Following Article 32, the Preliminary Hearing Officer submits recommendations.

The convening authority then decides whether to refer the case to court-martial.

Phase Four: Referral to Trial — Trial Typically 3 to 9 Months Later

Once referred, the case enters full trial litigation.

At this point:

  • Discovery continues

  • Motions are filed

  • Suppression issues are litigated

  • Experts are retained

  • Trial dates are set

General Court-Martial timelines often run:

  • 4 to 8 months from referral to trial

  • Longer in complex felony-level cases

  • Shorter in straightforward cases

Special Courts-Martial may move slightly faster.

Summary Courts-Martial move much faster — often within weeks.

But serious General Court-Martial cases routinely take 6 to 12 months from preferral to trial.

What Factors Extend Court-Martial Timelines?

Several variables determine whether a case moves quickly or slowly:

  • Volume of digital evidence

  • Number of witnesses

  • Expert testimony (forensics, medical, financial, psychological)

  • Overseas witness coordination

  • Motion complexity

  • Availability of judges

  • Speed of government discovery production

  • Defense litigation strategy

Former military judges understand how docketing pressure works.

Former prosecutors understand what slows investigations.

A defense team with that insider perspective can anticipate delay points — and sometimes use them strategically.

Trial Duration Itself — Days to Weeks

The trial phase varies significantly:

  • Summary Court-Martial: Often 1 day

  • Special Court-Martial: 2 to 5 days

  • General Court-Martial: 1 to 3 weeks is common

  • Complex sexual assault or fraud trials: Several weeks

General Courts-Martial involving:

  • Multiple alleged victims

  • Expert testimony

  • Digital forensic evidence

  • Voluminous financial records

can extend significantly.

But the trial itself is only a small portion of the total timeline.

Most of the time is spent preparing for it.

Sentencing — Immediately After Verdict

If convicted, sentencing typically follows immediately after findings.

This phase may last:

  • Several hours

  • Several days

depending on:

  • Number of character witnesses

  • Expert mitigation testimony

  • Documentary evidence

Preparation for sentencing begins months before trial.

Former judges know what actually influences sentencing decisions.

Former prosecutors know what arguments resonate.

That experience shapes preparation from day one.

Post-Trial Processing — 3 to 6 Months

After trial:

  • The record of trial is prepared

  • The convening authority takes post-trial action

  • The case is forwarded for appellate review

Post-trial processing can take:

  • 90 to 180 days

  • Sometimes longer in complex cases

During this time, confinement (if imposed) typically continues.

Appellate Review — 12 to 24 Months (or Longer)

General and Special Courts-Martial involving certain sentences automatically receive appellate review.

Military appellate courts operate on a slower timeline:

  • Briefing schedules

  • Oral argument

  • Written opinions

It is not unusual for appellate review to take:

  • 12 to 18 months

  • Sometimes 24 months or more

Total Timeline: Realistic Expectations

From investigation to final appellate resolution:

  • Simple cases: 6 to 9 months

  • Moderate cases: 9 to 18 months

  • Complex General Courts-Martial: 18 to 36 months

The phrase “court-martial process” often understates the duration.

This is federal litigation.

It unfolds over time.

Why Timeline Strategy Matters

Time is not neutral.

Time affects:

  • Witness memory

  • Expert availability

  • Clearance status

  • Retirement eligibility

  • Emotional strain

  • Financial stability

Experienced litigation teams use time strategically:

  • To negotiate

  • To pressure weak cases

  • To strengthen mitigation

  • To file suppression motions

  • To position favorable pleas

Delay is not always bad.

Acceleration is not always good.

Strategy determines which is advantageous.

How Early You Hire Counsel Changes the Timeline

The earlier a defense team is involved:

  • The more influence it has over investigation

  • The more leverage it has at Article 32

  • The more suppression opportunities exist

  • The more structured plea negotiations become

Waiting until referral to trial often limits strategic options.

Frequently Asked Questions

How long does a General Court-Martial take from start to finish?

Typically 9 to 18 months from investigation to trial. Complex cases can extend beyond that.

How fast can a Special Court-Martial happen?

In some commands, 4 to 6 months from preferral to trial is possible.

Can the defense slow down a court-martial?

Defense motions, expert retention, and discovery disputes can extend timelines when strategically appropriate.

Can I demand a speedy trial?

Yes. The UCMJ provides speedy trial rights, but invoking them must be strategic. Speed is not always advantageous.

How long do military appeals take?

Often 12 to 24 months, depending on the court’s docket and complexity.

Facing a Court-Martial or UCMJ Investigation?

If you are under investigation, charged under the UCMJ, or facing a court-martial, this is not the time for guesswork.

A court-martial is a federal criminal proceeding. The decisions you make early — what you say, who you speak to, whether you demand trial, whether you hire civilian counsel — can permanently affect your freedom, career, retirement, and reputation.
