Since 2005, couples who have entered into a civil partnership in the United Kingdom are recognised by the Isle of Man Department of Health and Social Security for pension purposes. The other rights of a civil partnership were not provided. In March 2009, the Chief Minister of the Isle of Man announced that a civil partnership bill would be introduced in October 2009. This bill would be mirrored on the UK one, providing same-sex couples with nearly all of the rights and responsibilities of marriage.
In February 2010, the civil partnership bill was introduced by the government and had its first reading in the House of Keys. The bill was passed 19 to 3 in the second reading on 30 March. Additional action toward passage was supposed to take place on 27 April, but was delayed for "technical" reasons. The bill passed the Clauses Stage on 25 May. On 22 June, the bill was approved in the third reading. On 29 June, the bill had its first reading in the Legislative Council. On 26 October, it passed second reading. On 9 November, the bill passed the Clauses Stage. On 23 November, the bill was passed in the third reading. On 15 March 2011, the bill was signed into law. It took effect on 6 April 2011.
