Hello,

Could you tell us more what you are trying to achieve? Do you want to transfer the domain or trying to setup a subdomain with a different project?

Thank you! I guess, I am transferring domain as described here https://vercel.com/docs/projects/domains/transfer-your-domain . However, as far as I see I can just transfer to a member of my team and for that I need to have paid account. Any possibility to do that on free account?

If no - can I just remove domain from my account and my colleague will add it from their account?

Yes, that should be possible. You can delete the domain followed by them adding it.
