For people in serious relationships, a wide range of options are available to make that relationship official in the eyes of the law.
A civil partnership is a legally recognized union between two individuals of the same or opposite sex, a union which gives the partners similar rights and responsibilities to married couples.
It is a relatively new concept in the United Kingdom, having only been introduced in 2005 with the passing of the Civil Partnership Act.
Registering a civil partnership
A civil partnership is defined as a relationship between two people who are not related by blood, and who have registered their partnership with the government.

The registration process involves signing a legal document, known as a civil partnership agreement, in front of two witnesses and a registrar.
The agreement specifies both the rights and responsibilities of the partners, including how property and other assets will be divided in the event of separation or death.
Legal rights and benefits
Once a civil partnership has been registered, the partners are legally considered to be in a civil partnership, and have the same rights as married couples in many areas, including inheritance, pensions, and next of kin.
They also have similar rights to married couples in relation to tax and other financial benefits, such as eligibility for tax credits and bereavement benefits.
Civil partnerships vs marriage
Civil partnerships are different from marriage in some important ways, and some key facts are necessary for understanding the difference.
For example, civil partners do not generally have the right to marry in a religious ceremony, and their partnership is not recognized as a marriage by some religious organizations.
However, civil partners can convert their partnership into a marriage, through a process called conversion.
Recent updates
It’s important to mention that the legal status of civil partnerships has been evolving in recent years.
In 2013, the Marriage (Same Sex Couples) Act was passed, which allowed same-sex couples to get married in England and Wales.
This in turn has led to a decrease in the number of civil partnerships being registered, as same-sex couples could now choose to get married instead.
However, the Civil Partnership Act remains in force, and civil partnerships are still available as an alternative option for same-sex couples, who prefer to have a legally recognized union that is distinct from marriage.
Preferences may arise from ideological or practical reasons, such as being in opposition to religions which have historically been prejudicial against homosexuality.
To sum up, a civil partnership is a legally recognized union between two individuals of the same or opposite sex, which provides the partners with similar rights and responsibilities to those who are married.
Civil partnerships are relatively recent additions in the UK, and provide same and opposite-sex couples with an alternative way to have their relationships legally recognized.
Although the legal status of civil partnerships has been evolving in recent years, and marriage is now open to same-sex couples as well as opposite-sex couples, civil partnerships remain an option for those who would prefer to have a legally recognized union that is distinct from marriage.
