Annulment in England and Wales Explained

Overview

Annulment is a legal process that ends a marriage by declaring that it was never valid, or should not continue because of a specific legal defect. It is different from divorce.

A divorce ends a valid marriage because the relationship has irretrievably broken down. Annulment, by contrast, is only available where the marriage falls within the legal grounds for void or voidable marriage under the Matrimonial Causes Act 1973.

This article explains when annulment may be available, how it differs from divorce, and why the legal test is strict.

Key Legal Considerations

What is the difference between void and voidable?

A void marriage is treated by law as invalid from the outset. Section 11 of the Matrimonial Causes Act 1973 sets out the main grounds, including where the parties were within prohibited degrees, either party was under 18, one party was already married, or the marriage was not valid under the Marriage Acts.

A voidable marriage is a marriage that is valid unless the court annuls it. Section 12 of the Act sets out the grounds, which include non-consummation, lack of valid consent, mental disorder, venereal disease, and certain gender recognition related grounds.

When might annulment be available?

Annulment may be considered where:

• the marriage was legally invalid;

• one party did not validly consent;

• there was a fundamental defect in the marriage ceremony or capacity to marry;

• the marriage was not consummated for reasons recognised by the statute;

• the case falls within a specific statutory ground for nullity.

What does the court look at?

The court will want to know:

• the date and place of the marriage;

• whether the ceremony complied with legal requirements;

• whether the parties had capacity to marry;

• whether there was real consent;

• whether any statutory bar applies;

• whether the applicant acted consistently with seeking annulment.

Is there a time limit?

Some voidable marriage claims are subject to statutory time limits and bars. In particular, section 13 of the Matrimonial Causes Act 1973 contains restrictions and bars to relief in certain cases.1

Because of this, delay can be important. A person considering annulment should obtain legal advice promptly.

What Factors Are Usually Considered?

In annulment cases, the court may consider:

• whether the evidence supports a specific statutory ground;

• whether the marriage was legally valid in the first place;

• whether there was knowledge of the defect;

• whether the parties lived together after the relevant issue became known;

• whether the application is being brought within the relevant time period;

• whether granting annulment would be unfair because of a statutory bar.

The key point is that annulment depends on law and evidence, not simply on the fact that the relationship has broken down.

Common Mistakes or Risks

Common mistakes include:

• assuming any unhappy marriage can be annulled;

• using annulment when divorce is the correct route;

• failing to identify whether the marriage is void or voidable;

• leaving the application too late;

• not gathering the right evidence about the ceremony or consent;

• overlooking the impact of religious or overseas marriage rules.

The risks include losing the chance to obtain annulment, having the application refused, or delaying the resolution of the wider family issues.

What Happens If You Choose the Wrong or Inexperienced Solicitor?

If the wrong route is chosen, the result may be:

• an application based on the wrong legal test;

• wasted time and costs;

• missed deadlines;

• weak evidence;

• avoidable emotional stress;

• confusion over financial and child arrangements.

Annulment cases are technical. Poor advice can quickly make the position more difficult.
