Yes, romantic partners can be added to your policy!
If you have been living together for more than 3 years, your partner will already be covered under the definition of ‘spouse,’ and you do not need to specifically list them on the certificate.
If you have not been living together for 3 years or want to specifically see them on the certificate, you can add your partner as an additional insured in the quote process.
Roommates or friends cannot be added and would require their own separate policy that’s under their own Duuo account and linked to their own email address.
