No. Both spouses do not have to agree to an annulment. One spouse may file a petition asking the court to annul the marriage. The other spouse must generally receive notice and have an opportunity to respond, but that spouse does not have the power to approve or veto the annulment.
If the respondent objects, the case becomes contested. The person requesting the annulment must then prove that a legally recognized reason existed when the marriage began.
The reverse is also true. Even if both spouses agree, the court will not grant an annulment simply because they prefer it over divorce. The facts must establish a valid legal ground. If you’re going through an annulment, contact a Salt Lake City annulment lawyer from Brown Family Law for guidance.
Can One Spouse File for Annulment Without the Other Spouse?
Yes. A spouse does not need permission from the other spouse to start an annulment case.
The person requesting the annulment files a petition with the appropriate court. That person becomes the petitioner. The other spouse becomes the respondent.
The petition generally identifies:
- The spouses and their current addresses
- The date and location of the marriage
- The legal ground for annulment
- The facts supporting that ground
- Whether the spouses have children
- Whether property or debts need to be addressed
- What orders the petitioner wants the court to enter
The respondent must then be properly served unless service is formally waived. Service gives the respondent notice of the case and an opportunity to participate. It is not a request for the respondent’s consent.
A spouse cannot prevent the case from being filed by refusing to sign paperwork.

What Happens if the Other Spouse Disagrees?
The respondent can file an answer denying the petitioner’s allegations and opposing the annulment.
The respondent might argue that:
- No recognized ground for annulment exists
- The alleged fraud or incapacity did not exist when the marriage began
- The petitioner knew the relevant facts before the wedding
- A statement was misunderstood rather than intentionally false
- The petitioner freely continued the marriage after discovering the problem
- The claim was filed after the applicable deadline
- The petitioner’s evidence is incomplete or unreliable
- Divorce, rather than annulment, is the legally appropriate remedy
The court may then schedule hearings, allow discovery, consider motions, hear testimony, and review documents.
Possible evidence in a contested annulment may include:
- Text messages and emails
- Marriage certificates
- Prior divorce decrees
- Financial records
- Medical records
- Police reports
- Witness testimony
- Social-media communications
- Evidence showing when the petitioner discovered the alleged problem
- Communications from before the wedding
The petitioner must establish the claimed ground through sufficient evidence. The respondent’s disagreement can make the process longer and more expensive, but disagreement alone does not prevent the court from granting an annulment.
A Calmer, Clearer Way Through Divorce
Can the Other Spouse Veto an Annulment?
No. The respondent does not have a unilateral veto. The respondent has the right to contest the allegations, challenge evidence, present witnesses, and make legal arguments. Those rights ensure that the court hears both sides before deciding the marriage’s legal status.
However, the respondent does not control the outcome.
A court may grant an annulment over the respondent’s objection if the petitioner establishes a legally recognized ground. A court may also deny the annulment despite the respondent’s agreement if the evidence does not satisfy the law.
What if Both Spouses Agree?
Agreement can simplify the case, but it does not guarantee an annulment. The spouses may be able to agree on:
- The facts surrounding the marriage
- The date the alleged problem was discovered
- Whether a prior marriage remained in effect
- Whether the marriage was ever consummated
- How property and debts should be handled
- Child custody and parenting arrangements
- Child support
- Whether either spouse will request financial support
- The language of a proposed decree
The parties may submit a stipulation or proposed judgment for the court to review.
However, a stipulation cannot manufacture a legal ground that does not exist. The judge must still determine whether the marriage was invalid or voidable under the applicable law.
For example, both spouses might agree that the marriage was a mistake and lasted only three weeks. Those facts do not automatically support annulment. A short marriage and mutual regret may make an uncontested divorce relatively straightforward, but they do not establish that the marriage was legally defective when it began.
Is an Agreed Annulment the Same as an Uncontested Annulment?
Usually, an agreed annulment is described as uncontested because the respondent is not opposing the requested relief.
That does not mean the case is automatic.
The petitioner must still:
- File the correct petition
- Identify a recognized annulment ground
- Establish the court’s jurisdiction
- Complete service or obtain a valid waiver
- Submit supporting evidence
- Address property, debts, support, and children when necessary
- Prepare the required findings and proposed judgment
- Obtain the court’s approval
A judge may request additional evidence or schedule a hearing even when both spouses have signed an agreement.
The marriage remains legally unchanged until the court enters the appropriate judgment.
What if the Other Spouse Does Not Respond?
An unresponsive spouse is not the same as an agreeing spouse.
If the respondent is properly served but does not file an answer within the required time, the petitioner may be able to request a default. The default process allows the case to move forward without the respondent’s active participation.
A default does not automatically prove that the marriage qualifies for annulment.
The petitioner may still need to:
- Demonstrate proper service
- Establish jurisdiction
- Prove the alleged annulment ground
- Submit testimony or affidavits
- Provide supporting records
- Prepare findings of fact and conclusions of law
- Submit a proposed judgment
Utah’s default-judgment procedures expressly include annulment cases. The person requesting default relief must file the required materials, including proposed findings and an order that matches the relief requested in the petition.
The court must still review and sign the judgment. Idaho’s family-law rules similarly allow a petitioner to request default when the respondent fails to answer. In cases that are not claims for a specific sum, the court may require evidence, establish the truth of an allegation, or investigate other matters before entering judgment.
Ignoring an annulment petition is therefore risky. It does not stop the case and can cause the respondent to lose the opportunity to contest important allegations.
What Legal Grounds Must Be Proven?
Commonly alleged grounds for annulment include:
- One spouse was already married to someone else
- The spouses were related within a prohibited degree
- A spouse was underage and required consent was not obtained
- A spouse lacked the mental capacity to consent
- Consent was obtained through fraud
- Consent was obtained through force or serious duress
- A qualifying physical incapacity existed when the marriage occurred
- The marriage was otherwise prohibited or void under state law
These grounds generally concern a condition that existed when the marriage began.
Events occurring only after the wedding usually do not make the marriage eligible for annulment. Infidelity, financial irresponsibility, incompatibility, frequent arguments, or emotional distance may support a decision to seek divorce, but they do not ordinarily show that the marriage was invalid at its inception.
What if the Spouses Agree to End the Marriage but Disagree About Annulment?
One spouse may believe the marriage should be annulled while the other believes it should end through divorce.
That disagreement can matter because annulment and divorce rest on different legal theories.
The spouse seeking annulment must show that a qualifying problem existed when the marriage began. The spouse seeking divorce generally does not need to prove that the marriage was invalid.
Depending on state procedure and how the pleadings are prepared, a party may request divorce as alternative relief. This can provide another path to ending the marriage if the court determines that the evidence does not support annulment.
The parties may also settle property, debt, support, or parenting issues while leaving the annulment question for the court to decide.
Can the Spouses Agree on Property but Contest the Annulment?
Yes. Agreement does not have to be all or nothing. The spouses may settle some issues while litigating others.
For example, they may agree about:
- Who keeps a vehicle
- How a joint account will be divided
- Who will pay a particular debt
- A parenting schedule
- Child support
- Possession of personal property
They may still disagree about whether fraud, force, incapacity, or another annulment ground has been proven.
Resolving the financial and parenting issues can narrow the case and reduce the number of matters the court must decide. The judge will still determine the marriage’s legal status.
Does Refusing to Sign Keep You Married?
Refusing to sign an agreement may prevent the case from proceeding as an agreed matter. It does not necessarily prevent the annulment.
If one spouse refuses to sign, the petitioner can proceed through the contested process. The petitioner must properly serve the respondent and prove the claim through evidence.
A person who receives annulment paperwork should not assume that refusing to sign will make the case disappear. The appropriate response is usually to review the allegations, understand the deadlines, and file the required answer.
Likewise, the petitioner should not assume that an unsigned agreement establishes opposition. The respondent may simply need more information, legal advice, or changes to the proposed terms.
Is Divorce Easier When the Other Spouse Opposes Annulment?
It may be. Annulment requires proof of a specific legal problem existing at the beginning of the marriage. Divorce generally provides a more direct way to end a valid marriage, particularly when no-fault divorce is available.
Divorce may be the more reliable option when:
- The evidence of an annulment ground is weak
- The dispute concerns events occurring after the wedding
- The applicable annulment deadline has passed
- The petitioner continued the marriage after learning the relevant facts
- The parties have extensive property or debts
- The primary goal is to end the marriage rather than establish that it was invalid
- Litigating a private fraud, capacity, or medical issue would be unnecessarily costly
The other spouse’s disagreement does not automatically make divorce the correct choice. However, it may change the cost, timing, privacy concerns, and evidence required to pursue annulment.
Call Brown Family Law to Learn More About Contested Annulments
Both spouses do not have to agree to an annulment. One spouse may file the petition without the other spouse’s permission. The respondent has the right to receive notice, file an answer, dispute the allegations, and present evidence, but cannot unilaterally block an annulment that is legally supported.
Agreement does not make approval automatic either. Even when both spouses want an annulment, the court must find that a recognized legal ground existed when the marriage began.
The strength of the evidence matters more than whether the spouses agree. Brown Family Law can help you evaluate the available grounds, respond to an annulment petition, and compare annulment with divorce.
