The Civil Partnerships, Marriages and Deaths (Registration etc) Act 2019 (c. 12) is an Act of Parliament of the United Kingdom which changes civil partnerships to include heterosexual couples, the way in which stillbirths are recorded and how a Coroner's inquest into stillbirths are conducted.

[1] This Act was created in response to the unanimous judgement of the Supreme Court of the United Kingdom in the case R (on the application of Steinfeld and Keidan) v Secretary of State for International Development in 2018 that ruled after the Marriage (Same Sex Couples) Act 2013, the Government was not justified in spending years reviewing the inequality between hetrosexual and homosexual couples in relation to civil partnerships.

The court made a declaration of incompatibility based on Article 14 (prohibition on discrimination) and Article 8 (right to respect for private life) of the European Convention on Human Rights (ECHR) on the basis that the Civil Partnership Act 2004 discriminates against heterosexual couples by precluding them from entering into civil partnerships.

Parents of babies who were still-born receive a medical certificate certifying the still-birth and, upon registration, could register the baby's name and receive a certificate of registration of still-birth.

When a pregnancy ended before 24 weeks gestation, however, there was no formal process for parents to legally register the loss.
