THE MYTH: There is a common misperception that if you live together for a certain length of time (seven years is what many people believe), you are common-law married. This is not true anywhere in the United States.
STATES THAT RECOGNIZE COMMON LAW MARRIAGE: Only a few states recognize common law marriages:
Georgia (if created before 1/1/97)
Idaho (if created before 1/1/96)
New Hampshire (for inheritance purposes only)
Ohio (if created before 10/10/91)
Oklahoma (possibly only if created before 11/1/98.
Oklahoma’s laws and court decisions may be in conflict about whether common law marriages formed in that state after 11/1/98 will be recognized.)
Pennsylvania (if created before 1/1/05)
