6. Texas calls it an "informal marriage," rather than a common-law marriage. Under § 2.401 of the Texas Family Code, an informal marriage can be established either by declaration (registering at the county courthouse without having a ceremony), or by meeting a 3-prong test showing evidence of (1) an agreement to be married; (2) cohabitation in Texas; and (3) representation to others that the parties are married. A 1995 update adds an evidentiary presumption that there was no marriage if no suit for proof of marriage is filed within two years of the date the parties separated and ceased living together.
7. Administrative order establishes that it arises out of a contract between two consenting parties who: (a) are capable of giving consent; (b) are legally capable of entering a solemnized marriage; (c) have cohabited; (d) mutually assume marital rights, duties, and obligations; and (e) who hold themselves out as and have acquired a uniform and general reputation as husband and wife. The determination or establishment of such a marriage must occur during the relationship or within one year following the termination of that relationship.
8. Kansas law prohibits recognition of common law marriage if either party is under 18 years of age. (2002 Kan. Sess. Laws, SB 486, §23-101).
9. Pennsylvania law was amended to read "No common-law marriage contracted after January 1, 2005 shall be valid." (Pennsylvania Statues, Section 1103)
