Preparation framework · Motion to suppress · For defense counsel
I have never actually drafted a motion to suppress. What is the structure?
The motion to suppress is the defense workhorse, and the first one is the hardest, because nobody writes down the shape of it. This is the documented structure a defender works through: the vehicle the motion is filed under, the grounds it can rest on, the sections of the written motion, and the hearing where it is argued. The rule is quoted verbatim from its official source; the grounds are stated as general doctrine, and the controlling authority for your facts is a matter for your own research, not a claim made for you here.
The vehicle: Florida Rule of Criminal Procedure 3.190
A Florida motion to suppress is a pretrial motion under Florida Rule of Criminal Procedure 3.190, Pretrial Motions. The rule carries two suppression tracks, one for evidence obtained in an unlawful search and one for a confession or admission obtained illegally, and it is quoted here verbatim from the official rule text. For the search-and-seizure track, a “A defendant aggrieved by an unlawful search and seizure may move to suppress anything so obtained for use as evidence because:”
“the property was illegally seized without a warrant;”
“the warrant is insufficient on its face;”
“the property seized is not the property described in the warrant;”
“there was no probable cause for believing the existence of the grounds on which the warrant was issued; or”
“the warrant was illegally executed.”
The rule also sets what the motion must contain: “Every motion to suppress evidence shall state clearly the particular evidence sought to be suppressed, the reasons for suppression, and a general statement of the facts on which the motion is based.” For a statement, the companion track provides that “the court shall suppress any confession or admission obtained illegally from the defendant.” And the timing rule is the same for both: “The motion to suppress shall be made before trial unless opportunity therefor did not exist or the defendant was not aware of the grounds for the motion”.

The grounds: what a motion to suppress can rest on
The grounds below are the general categories a motion to suppress is built on, each stated as general Fourth or Fifth Amendment doctrine. No case is cited and no holding is asserted; which ground the record supports, and the controlling authority under it, is a matter to research on the facts and the forum.
1. Unlawful stop · Fourth Amendment
Whether the initial seizure of the person was lawful. An investigatory stop is measured against whether the officer had reasonable, articulable suspicion of criminal activity at the moment of the stop, and a stop that outruns that suspicion, or that never had it, is the first place the record is attacked. Everything the stop produced rides on the answer.
- Identify the precise moment the person was seized and pin down the specific facts the officer knew at that moment.
- Ask whether those facts amount to reasonable, articulable suspicion of criminal activity, not a hunch, and confirm the standard the forum applies.
- Trace whether the stop was prolonged beyond its lawful purpose, because a lawful stop can become unlawful when it is extended without new justification.
2. Unlawful search or seizure · Fourth Amendment
Whether the search or the seizure of the thing was lawful. A warrantless search is presumptively unreasonable, so the analysis is whether the State can carry a recognized exception, or, when there was a warrant, whether it was supported by probable cause, sufficient on its face, and lawfully executed. The rule's own enumerated grounds map to this inquiry.
- Determine whether there was a warrant, and if not, which exception the State claims and whether its facts actually fit that exception.
- For a warrant, test probable cause, the particularity of the description, and whether the execution stayed within the warrant's terms.
- Read the rule's enumerated search-and-seizure grounds against the facts, because the motion is framed to the ground the record supports.
3. Unlawful arrest · Fourth Amendment
Whether the arrest itself was supported by probable cause. An arrest without probable cause is an unlawful seizure of the person, and it can taint the search incident to it, the statements that follow it, and the identifications that come after it. The lawfulness of the arrest is often the hinge the rest of the suppression argument turns on.
- Fix the moment of arrest and identify the totality of facts the officer had at that moment.
- Ask whether those facts establish probable cause to believe the person committed an offense, and confirm the standard the forum applies.
- Trace what flowed from the arrest, the search incident, the statements, the identifications, because an unlawful arrest can reach each of them.
4. Statements taken in violation of Miranda · Fifth Amendment
Whether a statement was obtained in violation of the custodial-interrogation warnings the Fifth Amendment requires. The threshold questions are whether the person was in custody and whether the questioning was interrogation, and from there whether the warnings were given, whether any waiver was knowing and voluntary, and whether questioning continued after the right was invoked.
- Determine whether the person was in custody and whether what followed was interrogation, because both are required before the warnings attach.
- Confirm whether the warnings were given and whether any waiver was knowing, intelligent, and voluntary on the specific facts.
- Trace whether questioning continued after the person invoked the right to silence or to counsel, and frame the statement-suppression track to Rule 3.190(h).
5. Fruit of the poisonous tree · Fourth and Fifth Amendments
Whether evidence derived from an earlier illegality must be suppressed along with the illegality itself. Once a stop, search, arrest, or statement is shown to be unlawful, the analysis follows the chain: the physical evidence, the statements, and the identifications that the illegality produced are examined for whether they are the fruit of it, subject to the doctrines the State may raise in response.
- Map the causal chain from the initial illegality to each piece of evidence the State intends to use.
- For each downstream item, ask whether it was come at by exploitation of the illegality or by a means sufficiently distinguishable to be purged of it.
- Anticipate the State's responses, the doctrines it raises to break the chain, and confirm the controlling authority for each on the facts and the forum.
The structure of the written motion
The written motion has a documented shape. Each section below is a drafting step, stated generally; the legal-grounds section is where the controlling authority is marshalled, and that authority is a matter for your own research on the facts.
1. Caption
The style of the case, the court, the case number, and a title that identifies the motion and, where it helps the court, the specific evidence it reaches. The caption tells the court what it is being asked to decide before it reads a word of argument.
2. Factual basis
A general statement of the facts on which the motion is based, drawn from the discovery and the record. The rule requires the motion to state the facts, so the factual basis is written to be specific enough to frame the legal grounds without arguing them, and grounded in the record the hearing will develop.
3. Legal grounds
The specific ground or grounds the suppression rests on, framed to the constitutional source and, for a search-and-seizure motion, to the rule's enumerated grounds. This is where the controlling authority is marshalled; that authority is a matter for independent research on the facts and the forum, and no case is asserted for you here.
4. Evidence to suppress
A clear statement of the particular evidence sought to be suppressed. The rule requires the motion to state clearly the particular evidence and the reasons for suppression, so this section names the items with enough particularity that the court and the State know exactly what is at stake.
5. Hearing request
A request for an evidentiary hearing on the motion. Because the court first determines whether the motion is legally sufficient before hearing evidence, the motion is drafted to clear that legal-sufficiency gate, and the hearing request sets up the burden-shifting sequence the rule describes.
The hearing: the burden-shifting sequence
The rule sets the sequence of the hearing, and the sequence is quoted here from its verbatim text. First, “Before hearing evidence, the court shall determine if the motion is legally sufficient.” If the court hears the motion on its merits, “the defendant shall present evidence supporting the defendant’s position and the state may offer rebuttal evidence.” The steps below walk that sequence and note what the hearing is built to elicit.
1. Legal-sufficiency gate
Before hearing evidence, the court determines whether the motion is legally sufficient; if it is not, it is denied without a merits hearing. The drafting target is to plead the ground and the facts specifically enough that the motion clears this gate and earns the evidentiary hearing.
2. Defendant's prima facie showing
On the merits, the defendant presents evidence supporting the position. For a warrantless search this is the showing that raises the presumption of unreasonableness and puts the State to its justification; the defense case is built to establish the predicate the ground turns on.
3. The State's response
The State may offer rebuttal evidence. Where the search was warrantless, this is where the State carries its burden to establish a recognized exception; where there was a warrant, the litigation turns to probable cause, particularity, and execution. The cross-examination is aimed at the specific element the State must carry.
4. What to elicit
The hearing is the record. Elicit the specific facts the ground depends on: the moment and basis of the stop or arrest, the scope and manner of the search, the custody and interrogation facts for a statement, and the chain from any illegality to each downstream item. The goal is a record that supports the legal ground, not a concession.
Turn the structure into the filed motion
The motion is only as strong as the record behind it, so the discovery demand runs first: the reports, the body-camera and dashboard video, the dispatch and stop records, the warrant and its affidavit, and the statement record are things to demand in writing early, because the suppression hearing is built on that record and the credibility of the officers who made it.
This framework is the shape of the motion. When you need the per-ground suppression motion already built, the source-cited template drawn to the specific ground, the Suppression Motion Pack is the drafted set. To attack the credibility of the officers whose stop, search, or arrest the motion challenges, run the officer against their record with Officer Lookup. And to demand the reports, video, and warrant record the hearing is built on, start with the free discovery-demand checklist.
The per-ground suppression motion
Per ground: a structured motion-to-suppress template drawn to the specific ground, the required contents from the rule, and the argument scaffold for the hearing. The framework tells you the shape; the pack is the drafted motion for the specific ground.

A preparation framework for defense counsel: not legal advice, and not a substitute for independent research or judgment. The available grounds and the controlling authority depend on the specific facts and the jurisdiction. Confirm the rule and the law your forum applies and adapt every step to the facts of your case.
