I recently received an email from a reader of MR KOACHMAN blog, who said that he has been chosen as the best man for his friend’s wedding. Being his first time, he was asking for a guide to help him perform his best man duties well.

I promised him I was going to publish this guide, so here it is … a helpful list of things to do. And if you are a groom-to-be, share this article with your best man before further discussion.

The best man is the groom’s right-hand man, usually a close friend or close relative of the groom. This is pretty much the highest honor your friend can bestow upon you, having selected you to be by his side on the day he makes the biggest commitment of his life.

We all know that planning a wedding isn’t easy – the groom is already loaded with a lot of responsibilities. It is the responsibility of the best man to lighten this load for the groom by assisting him in completing his jobs before, during and after his wedding.

What are the best man’s duties? Here is a comprehensive list of responsibilities and duties:

BEFORE THE WEDDING (During the Wedding Planning)

Best Man Duties #1: You are the Team Lead for this Wedding project.
  • The best man should be familiar with the wedding plan and activities of that day.
  • This is because everyone (including vendors, ushers, servers, the groomsmen, couple’s friends and family members) will look up to you to give them updates on what’s going on, what’s happening next etc.


Best Man Duties #2: Who and Who Are Attending? Get to Know Them and Their Job Functions
  • The best man needs to be aware of who all the people who will be assisting in the wedding activities – the ushers, servers, chillers, caterers, decorators etc..
  • He should have all their contacts and know what duty they’ll have on the day so he can follow up with them and make sure everything is in order and already taken care of before the wedding starts properly.

Best Man Duties #4: Are you working with a Wedding Stylist? 
  • If yes, ensure you work hand in hand with the groom and the stylist to agree on the budget and other details so you can communicate clearly to the groomsmen in case they want to start contributing financially towards their own outfit.


Best Man Duties #5: Financial contributions. 
  • Ideally, the couple should pay for the wedding suits, especially those of the groom and best man. However, if it’s decided that everyone should contribute, agree on the exact figures and discuss this at this planning stage with the groomsmen and be open about it.


Best Man Duties #6: Set up a group chat on a messaging service for proper coordination.
  • This will certainly save time instead of organizing frequent face to face meetings. Create a group chat on WhatsApp, Facebook or any other convenient messaging service app. This is so that you will have everyone in one place for easy coordination and discussions.
  • You can throw updates on the same group chat as you proceed, plan the bachelor party with those involved and request for whatever information you need from anyone.


Best Man Duties #7: Are you giving the Best Man’s Speech?
  • Traditionally, the Best man is required to give the Best Man’s Speech. So if you have been asked to do this it’s a great honor, so make sure you write and practice your speech for excellent delivery on the D-Day.
