HOW TO PROVE CONVERSATIONS OR
STATEMENTS IN EVIDENCE?
By Atty. Florante A. Zagada.
Conversations of persons are frequently introduced as evidence during court trials. The statement you utter to people maybe used as an evidence against you. So be careful with what you say because careless words may betray you.
However, since these conversations are out-of-court statements, they are usually hearsay and are inadmissible unless they are being offered for a non-hearsay purpose or are an exception to the hearsay rule.
Accordingly, whenever you intend to introduce a conversation or statement in evidence, review the evidentiary basis for its admission.
First, is the statement being offered for the truth of the matters asserted in the statement? If not, there is no hearsay problem. If so, the statement is hearsay.
Second, if it is hearsay, is there any exception to the hearsay rule that applies? If so, the statement is admissible. You should always review Rule 130, Sec. 37 on Hearsay Rule and Sec. 21-33 of the Rules of Court to determine if any exception is applicable.
The most common exception is admissions and confessions. (Rule 130, Sec.27-34. Whenever one party makes a statement and an opposing party wishes to introduce it, the statement is ordinarily admissible. If the statement made by a party opponent is part of a conversation, the conversation between the party opponent and another person is admissible, since the entire conversation is necessary to put the party oppo\nent’s statements in context. Statements by agents and employees of party opponents are also admissible. These statements are admissible against the principal, the party opponent, if there is independent evidence that the agency relationship existed, that the agent’s statements were made during the course of the agency relationship, and that the statements were about matters within the scope of the agent’s employment. The same basic rules also apply to statements made by co-conspirators in criminal cases.
There are, of course, many hearsay exceptions to out-of-court statements. Common ones include excited utterances, statements against interest, statements of then-existing mental or physical conditions, and statements made for the purpose of diagnosis and treatment.
As always, you must think expansively whenever you are trying to introduce out-of-court statements. Where necessary, research the problem and have supporting authority available when you introduce the statement in evidence.
Conversations also need proper foundations to be admissible. The basic requirement is authentication, that is, the witness must reasonably identify the participants to the conversation. The foundation should be established for every conversation, even if the opposing side may not object to its absence.
First, opposing counsel can al-ways decide to object, thereby breaking up the flow of your direct examination. Second, the foundation enhances your witness’ credibility by demonstrating his ability to remember details.
ELEMENTS OF FOUNDATION:
The following foundation elements must be established to admit in evidence a conversation between two or more persons:
1. When the conversation occurred.
2. Where the conversation occurred.
3. Who was present during the conversation.
4. Who said what to whom.
It is not necessary that the witness actually have participated in the conversation. He may properly testify to a conversation he witnessed be-tween two or more other persons as long as the conversation is otherwise admissible under hearsay rules.
EXAMPLE 1: (Admission by-Party-Opponent)
Q: Did you personally talk with Dave Reyes?
A: Yes, I did.
Q: When did that conversation with the defendant take place?
A: I talked to him on October 6, 2026.
Q: What time of day was that?
A: That was about 3:00 in the afternoon.
Q: Where did that conversation take place?
A: We talked in his office.
Q: What’s the address of his office? A: No. 15 St. Tomas Avenue, Makati City.
Q: Who was present during that conversation?
A: There was just myself and Mr. Dave Reyes.
Q: What did you and Mr. Reyes say at that time?
A: I said: “Mr. Reyes, you still owe me P50,000 for the roofing job on your house.” He said: “I know I do. I just don’t have the money to pay you right now.”
Example 2: (Excited Utterances)
Q: What happened right after you heard the shot?
A: Well, people came running to the scene.
Q: Did you know any of them?
A: Other than my wife, no.
Q: What happened next?
A: Well, there was a middle-aged man standing just a few feet from me, and he suddenly screamed: “Look out! He’s got a gun!”
HOW TO PROVE TELEPHONE CONVERSATION:
Telephone conversations, also commonly admitted in trials, are introduced in much the same way as face-to-face conversations, but have an additional element.
The witness must be able to identify the speaker on the other end of the line. There are four basic factual situations under which the foundation for the identity of the other speaker can be established.
1. THE WITNESS KNOWS OTHER PERSON.
Elements:
The following elements must be established for a telephone conversation between two persons, where the witness knows and recognizes the
other person’s voice.
1. When the conversation occurred
2. Where the conversation occurred (where witness was)
3. Witness recognized the other voice
4. How witness knows the other voice
5. Whose the other voice was
6. What other persons participated
7. Who said what to whom.
It is not necessary to show who placed the call. Where this is known,
of course you should show it, since it adds to the credibility of the witness
and the reliability of the voice identification, but that knowledge is not a
necessary element of the foundation. As in face-to-face conversations, it is
also not necessary that the witness have personally participated in the con-
versation, just that he heard it.
EXAMPLE:
Q. At approximately 4:00 P.M. on October 5, 2026, where were you?
A. I was in my house.
Q. Did anything happen at that time?
A: Yes:
Q. What happened?
A. The telephone rang.
Q: What did you do?
A: I picked up the phone and said “hello.”
Q: Where were you when the telephone rang?
A: I was in the kitchen right next to the phone.
Q: What happened next?
A: A voice answered.
Q: Did you recognize that voice on the other end of the line?
A: Yes, I did.
Q: How did you recognize that voice?
A: I have talked to the same person numerous times over the past
several years, in person and over the telephone.
Q: Whose voice was it?
A: It was Dave Reyes.
Q: Did anyone else take part in that telephone conversation?
A: No
Q: Tell us what you said and what he said during that conversation?
A: He said: “Hi, this is Dave Reyes.” I said: “Hi.” He said: “You still
owe me P50,000.00 for the roofing job on your house.” I said: “No, I don’t. Your job was defective. I won’t pay it.”
Note that it is not necessary to show that the voice on the other end can be recognized because of previous telephone conversations. Face-to-face conversations are a sufficient basis for the identification. Of course, where the previous conversations were on the telephone, this enhances the reliability of the identification.
It would be improper to bring out that the caller identified himself before establishing the foundation. The concept behind the foundation requirement is voice recognition, which should eliminate imposters posing as someone else. The identification of the caller can properly be brought out in the conversation itself.
2. THE WITNESS DOES NOT KNOW THE OTHER PERSON, BUT LATER LEARNS IDENTITY THROUGH SUBSEQUENT CONVERSATIONS.
ELEMENTS:
The following elements must be established for a telephone conversation between two persons, where the witness learns the identity of the
other person through later face-to-face conversations.
1. when the conversation occurred
2. where the conversation occurred (where witness was)
3. witness did not recognize the other voice at the time
4. at later dates, witness talked to the other voice personally
5. witness now recognizes other voice during the call
6. who other voice was
7. what other persons participated
EXAMPLE:
Q: On April 25, 2025, at approximately 4:00 P.M., where were you?
A: I was in the kitchen of my house.
Q: What happened at that time?
A: The phone rang.
Q: What did you do?
A: I picked up the phone and said “hello.”
Q: Did you recognize the voice on the other end?
A: Not at that time.
Q: Mr. Sarmiento, on April 30, at approximately 4:00 P.M., where were
You?
A: I was in Dave Reyes’ office in Makati City.
Q: Did you have a conversation with him?
A: Yes, I did.
Q: Since that day, have you had any other conversations with Dave Reyes?
A: Yes.
Q: About how many?
A: Maybe 10 or 12.
Q: Mr. Sarmiento, turning back to the telephone call you received on
April 25, 2025, are you now able to recognize whose voice was on
the other end?
A: Yes, I am.
Q: Whose voice do you now recognize it to be?
A: Dave Reyes.
Q: Were any other persons present during that conversation?
A: No.
Q: What did you say and he say at that time?
A: He said: “You still owe me Php 50,000 for the roofing job on your
house.” I said: “No, I don’t. The job is defective.”
3. THE WITNESS DOES NOT KNOW THE PERSON, BUT LATER LEARNS IDENTITY THROUGH SOME INSTRUCTION.
ELEMENTS:
The following elements must be established for a telephone conversation between two persons, where the witness learns the identity of the other person through either a prior or subsequent transaction (other than a conversation).
1. when the conversation occurred
2. where the conversation occurred
3. witness did not recognize the other voice at that time
4. witness was engaged in a prior or subsequent transaction that
identified the voice for him (in some jurisdictions the subsequent
act that identifies the voice must have occurred prior to the beginning of litigation)
5. witness now knows the other voice what other persons participated.
6. who said what to whom.
EXAMPLE:
Q: On April 25, 2025, at approximately 4:00 P.M., where were your
A: I was in the kitchen of my house.
Q: Did anything happen at that time?
A: Yes, the phone rang.
Q:What did you do?
A: I picked up the phone and said “hello.”
Q: Did you recognize the other voice at that time?
A: No.
(Show Plaintiff's Exhibit A to opposing counsel.)
Q: Mr. Sarmiento,I show you Plaintiff's Exhibit A. Do you recognize it?
A: Yes, I do.
Q: When did you receive this letter?
A: I got it around April 30, 2025.
Q: Is that letter in the same condition now as it was on the date you
received it?
A: Yes, it is.
Q: Do you recognize the signature at the bottom of the letter?
A: Yes. I’ve seen it several times before.
Q: Whose signature appears at the bottom?
A: Dave Reyes.
Q: Please read the first line of that letter to the court.
“Dear Mr. Smith, I am writing to confirm the substance of the
telephone call I made to you the afternoon of April 25, 2025.”
Q: : Do you now know who the voice on the telephone was on April
25, 2025 at approximately 4:00 P.M.?
A: Yes, I do.
Q:: Whose voice was it?
A: It was Dave Reyes..
Q: Did anyone else take part in the telephone conversation?
A: No.
Q: What was said during the conversation?
A: He said: “Mr. Smith, I am calling you about your roofing problem. We can resurface your roof for PHP 50,000” I said: “That looks pretty good to me.”
What have you established? There was only one person speaking on the telephone. Hence, only that person, in addition to yourself, could reasonably know the nature of the conversation. When the subsequent letter arrives, you know from its contents who the previous caller was. The letter identifies the caller and is admissible as an admission of the party-opponent. While not as reliable as voice recognition, it is sufficient to
qualify the conversation for admission.
