In a tenants in common account, each owner holds a pro-rata share (e.g., 50%) and can only issue instructions for their portion, with no right of survivorship. KYC information is required for both owners. The feedback from the document states:

"If more than one person owns an account and it is not specifically identified as being a joint account, each owner owns a pro-rata share of the account, unless ownership is divided in another manner and noted on the account. Where an account is held as tenants in common, there is no right of survivorship and each owner, unless otherwise specified, can only give instructions with regard to the pro-rata portion of the account."
