If you want to get married in South Carolina, you are going to need a valid marriage certificate.
The South Carolina Supreme Court abolished recognition of common-law marriage in a decision last week, report the Legal Profession Blog, the Post and Courier, and WYFF. The decision applies to future relationships and not to people already in common-law marriages.
Fewer than 10 states recognize common-law marriage, according to the opinion. The most recent state to abolish common-law marriage was Alabama, which adopted a law barring such marriages in 2016.
