Add Additional Contacts to an Existing Opportunity
Follow these steps to add an existing co-buyer, realtor, lender, or other contact to an Opportunity and ensure the correct relationship is captured using association labels.
Add a Contact to an Opportunity
- Navigate to the Opportunity (Deal) that needs an additional contact associated with it.
- Open the Opportunity record.
- In the right-hand panel, locate the Associated Contacts section and click + Add.

Search for an Existing Contact
Before creating a new contact, search HubSpot to determine whether the contact already exists.
- Enter the contact's name, email address, or phone number in the search field.
- If the contact is found, select the contact.
- Click Next at the bottom of the screen.
Note: If the contact does not exist, create the contact record before associating it with the Opportunity.
Apply an Association Label
Association labels identify the contact's relationship to the Opportunity.
- Click + Add Association Label.
- Select the association label that best describes the contact's relationship to the Opportunity.

Common labels include:
- Buyer 2
- Buyer 3
- Lender
- Real Estate Professional
- Click Save at the bottom of the screen.
Important: Selecting the correct association label helps ensure accurate reporting, automation, and record management.
Expected Result
Once saved, the contact will appear in the Associated Contacts section of the Opportunity with the selected association label applied. This allows the contact to be properly identified throughout HubSpot reporting and automated processes.
