I wonder if it has more to do with survivorship in recording the deed in Orange County. As part of the contract buyers select from a few “deed vesting” options - tennants in the entirety, joint tennancy, tennants in common etc. which may change how they are referred to when recording the deed or the transfer of the deed. Our recent deed recording listed our sellers in the legalese as “X and X, Husband and Wife, herein after referred to as grantor.....” Perhaps, pure speculation on my part, a same sex couple on a deed may be listed for example as “X and X, a New Jersey married couple herein after referred to as grantor/grantee”....etc
