How to Log a Phone Call Properly (and Why It Matters Later)

A phone call is the one conversation in a matter that leaves no record unless you write one. Emails and letters document themselves; calls vanish. Months later, when someone says "I told you about the leak in March" or "you promised me an extension", the only evidence is whoever wrote the better note at the time. A proper call log takes two minutes and settles arguments that would otherwise be your word against theirs.

What to record

• Date and time of the call, and its approximate length.
• Direction — who called whom, and on which number.
• Who was on the call, by full name and role, and how you know it was them (their usual number, they confirmed details, you called a number on file).
• The purpose in one line.
• What was said, in order, focusing on facts, requests, promises and refusals.
• Exact words for anything that matters, in quotation marks.
• What was agreed and who will do what, by when.
• Your name and when you wrote the note, if not straight after.

Write it straight away

A note written during or immediately after a call is far more credible than one written the next day, and far more accurate. Memory fades and reshapes itself within hours. If you cannot write the full note immediately, jot the key points and the time, then complete it the same day, noting when you did.

A worked example

9 April, 12:40, approx. 8 minutes. Incoming call from Daniel Osei (tenant, 14 Harbour Row) on his usual mobile. Purpose: rent payment. He said his April payment would be late because "my hours were cut last month". He asked whether he could pay half on the 15th and the rest on the 30th. I said I would need to check and confirm in writing. No agreement made on the call. Action: I will email him by 11 April with a decision. Noted by P. Anand at 12:55.

Notice what it does: it records the request without implying agreement, quotes the reason in his words, and ends with a dated action.

Confirm important calls in writing

If a call produces an agreement, a decision or a warning, follow it with a short email: "Thanks for your call today. To confirm, we agreed..." It turns your note into something the other person has seen and could have challenged. File the email next to the call note.

Recording calls

Audio recordings can be valuable, but the law on recording calls, and on telling the other party, differs widely between jurisdictions. Check the rules where you and the other person are before you record, and tell people when you do. A recording does not replace a note: nobody will listen to forty minutes of audio to find one sentence.

Keep it with the matter

A call log in a personal notebook or a phone's notes app is as lost as an email in a personal inbox. Log calls in the same record as the rest of the matter, so that anyone reading it sees the full conversation in date order. The case for moving correspondence out of individual mailboxes is in the hidden cost of using email as a filing system, and the general habits of good notes are in how to write a case note that lasts.
