Article 78 of the Civil Code of Guatemala (1963) defines marriage as a social institution where a man and a woman are legally united.

In 1963, Hawaii amended its Penal Code to prohibit people from "wearing clothing of the opposite sex with intent to deceive other people in identifying their sex" with up to a year in prison as punishment. Commonly referred to as the "intent to deceive" law, the law in practice criminalise the gender expression of transgender people in Hawaii with several trans women being forced to wear pins saying "I AM A BOY" to avoid arrest while humiliating them in the process. The law would be repealed in 1972, effective 1973.

The 1963 Penal Code of the Solomon Islands only criminalised male homosexuality until 1990.

In 1963, the first fully reimbursed gender reassignment surgery in Polish history (MTF) was performed in Warsaw. Until the first health care facility in Poland was established, which specialized in the diagnosis and treatment of transgender people, hormonal therapy and professional diagnosis of gender dysphoria were not possible.

LGBT people regardless of gender are allowed to engage in such acts once old enough according to the law. In 1953 the police was ordered to refrain from enforcing the law against homosexual acts by the Israeli government. In 1963 Israel's Highest Court decides that individuals who committed consensual homosexual acts privately couldn't be punished and even before that there are no records of punishments by civilian courts against people who committed consensual homosexual acts privately. The law was officially repealed by the Knesset ( the Israeli Parliament ) in 1988, but it's enforcement was illegal since 1963 in most cases.
