Is my Marriage or Civil Partnership legally recognised?

What is a Marriage

A Marriage is a legally recognised status which attaches to it certain legal rights and responsibilities. There are strict rules on who can and who cannot marry each other. A Marriage may be classed as valid, void or voidable depending on the circumstances. 

What is a Civil Partnership

This is a new status introduced by the Civil Partnership Act 2004, which came into force December 2005. This is very similar to marriage but not identical.

The Law of Nullit

The Law of Nullity tells us who may marry or enter into a civil partnership and with whom.

Valid Marriage/ Civil Partnership

These are binding on everyone and can only be ended on death, divorce or dissolution.

Void Marriages/Civil Partnerships

These Marriages/ Civil partnerships never actually come into existence because of a fundamental defect  

Voidable Marriages/Civil Partnerships

These partnerships are valid until they are annulled 


A marriage that has complied with no formalities and with no legal consequences 

When are Marriages/Civil Partnerships VOID

Under section 11 of the Matrimonial Causes Act 1973, a marriage that was celebrated after 31st July 1971 will be void on the following grounds: 

  • The parties are within the prohibited degrees of relationships

  • Either party is under the age of sixteen

  • At the time of the marriage either party was already lawfully married or in a civil partnership with someone else

  • Parties are not respectively Male and Female

16 and 17year olds will need permission from their legal parent /guardian, However if they do not get permission the marriage will not be void. If the parent/guardian puts a notice against the marriage on the Marriage register then if the marriage goes ahead it will be void in the eyes of the law. 

The Prohibited Degrees of a Relationship

If any two people within the list below marry each other, they are said to be in the prohibited degrees of a relationship and the marriage will be automatically VOID.
