Capital One's steps

Update Social Security first. Then visit a branch, or call and ask for a secure upload link. You need a document with your new name and a W-9 signed by hand.

Open Capital One's page

Have these ready

A copy of your marriage certificate, divorce decree or court order (most companies ask for one).
Your updated driver's license or ID, if you have it. Social Security comes first, then the DMV.
Your account number, and the name the account is in now.
