I recently had the same problem, you'll need to request that HubSpot delete these forms via support or delete the forms in Business Manager if you have a way to get back into the account or have the new owner delete them.
Hi there. Im facing the same issue. Can somebody help me deleting some old forms im not using anymore, so i could be able to delete contact properties that are useless?
This procedure requires that you provide confidential information, for the security of the information, and considering that you have a paid account, you should directly contact our support team. They will be happy to ask you a few questions to facilitate the deletion of those forms on your behalf.
Can you confirm that the page associated with the form you want to delete is not enabled for lead syncing anymore? If it is, the form cannot be deleted (it will just be recreated following deletion)
If we delete a lead ad form but you later re-enable the associated Facebook business page/LinkedIn ad account, the form will automatically be re-synced/re-created
If the page isn't enabled for lead syncing anymore, can you tell me the name of the property tied to this lead ad form you want to delete?
