Final answer:
The requirements for a common-law marriage include living together, presenting oneself as married, and intending to marry, but do not typically include getting blood tests.
Step-by-step explanation:
The requirements for establishing a common-law marriage generally include cohabitation, presenting oneself as a married couple, and sharing the intention to be married. However, getting blood tests is typically not a requirement. Instead, a significant period of living together, intentions to marry, and holding oneself out as married are key components of forming a common-law marriage. Cohabitation has become more common and socially acceptable, with many couples viewing it as a step toward marriage or a 'trial run.' Over time, the legal recognition of relationships has evolved, reflecting changes in society's views on marriage and cohabitation.
