From a shallow perspective, both divorce and annulment serve the same basic purpose of dissolving a marriage. However, when you dig deeper, these are fundamentally very different legal proceedings with different standards of proof, different financial implications, and very different outcomes in the eyes of the law.
When a couple obtains a divorce, they are recognized as formerly married. An annulment — known in Colorado as a declaration of invalidity of marriage — ends the marriage as if it never legally existed. In other words, when a marriage is annulled, it is treated as having been illegitimate from its inception.
There are a number of factors you must consider before deciding between a divorce and an annulment, including the grounds available to you, the length and nature of your marriage, and your financial circumstances. The family law attorneys at Brighter Day Law in Colorado Springs focus on providing you with the guidance you need to make a fully informed decision.

What Is a No-Fault Divorce and an Uncontested Divorce?
When you or your spouse files a petition for dissolution of marriage in Colorado, a no-fault divorce may be granted depending on the circumstances. As the name suggests, neither partner needs to prove that the other was at fault for the breakdown of the marriage. Colorado is a pure no-fault divorce state — the only recognized ground for dissolution is the irretrievable breakdown of the marriage, commonly referred to as irreconcilable differences.
If it can be established that your relationship is unsustainable due to major incompatibility and irresolvable disputes, you are most likely to qualify for a no-fault dissolution. If there are any unresolved issues — such as property division, spousal maintenance (alimony), child support, child custody, or parenting time and visitation — the court will resolve those matters before issuing the final decree.
If there are no unresolved issues between you and your spouse, you may qualify for an uncontested divorce — a more streamlined form of dissolution in which both partners reach written agreement on all matters, including asset and liability division and any child-related issues. This written agreement is known as a Divorce Settlement Agreement (or Separation Agreement) and is submitted to the court for approval. Because there are no contested issues for the court to adjudicate, an uncontested divorce is typically simpler, faster, and significantly less expensive than a contested proceeding.

What Is an Annulment (Declaration of Invalidity) in Colorado?
In Colorado, what is commonly called an “annulment” is formally known as a declaration of invalidity of marriage, governed by Colorado Revised Statutes § 14-10-111. Unlike a dissolution of marriage, which acknowledges that a valid marriage existed and then legally ends it, a declaration of invalidity treats the marriage as never having been legally valid in the first place.
Child custody, parenting time, property division, and other related issues are still addressed by the court in an annulment proceeding — just as they would be in a divorce. The critical distinction is the legal status of the marriage itself: a dissolved marriage is a former marriage, while an annulled marriage is treated as if it never occurred.
Under C.R.S. § 14-10-111, a Colorado court may enter a decree of invalidity only when specific legal grounds can be proven by a preponderance of the evidence. These grounds include:
- Lack of capacity to consent: One or both spouses lacked the mental capacity to consent to the marriage, including due to intoxication, substance use, or mental incapacity at the time of the ceremony
- Underage marriage: One or both spouses had not reached the lawful age of consent, and parental or judicial approval was not obtained
- Bigamy: One spouse was already legally married to another person at the time of the marriage
- Prohibited relationship: The parties are related by blood (consanguinity) within prohibited degrees of kinship
- Fraud or misrepresentation: The marriage was induced by fraud, such as the concealment of a prior child, a serious undisclosed illness, or other material misrepresentation
- Duress or force: One spouse entered the marriage under coercion or undue pressure
- Inability to consummate: One spouse was permanently physically incapable of consummating the marriage and the other spouse was unaware of this at the time of marriage
Because the standards of proof are demanding and the qualifying grounds are narrow, declarations of invalidity are considerably rarer than dissolutions of marriage in Colorado. It is essential to consult with a Colorado Springs divorce attorney to determine whether the facts of your situation actually meet the statutory threshold before pursuing this route.
Divorce vs. Annulment: Key Differences
When a marriage becomes a burden rather than a bond, ending it is a reasonable choice. The question is which legal mechanism applies to your situation.
You should seek a declaration of invalidity only when you have legally sufficient grounds to argue that your marriage was never valid to begin with. If both partners acknowledge the existence of a valid marriage but wish to end it, a dissolution of marriage (divorce) is almost certainly the correct path.
| Factor | Divorce (Dissolution) | Annulment (Declaration of Invalidity) |
|---|---|---|
| Legal effect | Ends a valid marriage | Treats marriage as never having existed |
| Grounds required | Irretrievable breakdown (no-fault) | Specific statutory grounds must be proven |
| Court appearance | Not always required | Both parties typically must appear |
| Residency requirement | 91-day Colorado residency required | No residency requirement |
| Property division | Equitable distribution of marital assets | Returns parties to pre-marriage positions |
| Prenuptial agreements | Remain enforceable | Become void |
| Waiting period | May apply in some circumstances | Generally none |
| Spousal benefits | Subject to court order | Typically revert to pre-marriage status |
What Are the Advantages of Annulment Over Divorce?
Annulments are relatively rare because of the stringent legal conditions required. However, some people do prefer to pursue a declaration of invalidity when the grounds exist. Potential advantages include:
- There is no residency requirement for a declaration of invalidity in Colorado, unlike divorce, which requires 91 days of established Colorado domicile
- Because all transactions that occurred during an annulled marriage may be treated as invalid, parties are generally restored to their pre-marriage financial positions — which can be advantageous in short marriages with significant asset inequality
- Social security benefits that were suspended due to the marriage are automatically reinstated once the annulment is finalized
- A declaration of invalidity automatically voids any prenuptial or postnuptial agreement that was executed in connection with the marriage
- For individuals with strong religious or cultural beliefs about divorce, an annulment may carry a social or spiritual significance that a dissolution of marriage does not
Does Divorce Have Any Benefits Over Annulment?
In most situations, a dissolution of marriage is the more practical and more readily achievable option. Key advantages of divorce over annulment include:
Easier to obtain. Because divorce in Colorado requires only a showing of irretrievable breakdown — not proof of a specific qualifying ground — it is accessible to virtually all married couples who have decided to separate. An annulment, by contrast, places a burden of proof on the petitioning spouse and requires establishing narrow, fact-specific statutory grounds.
No court appearance required in many cases. An uncontested dissolution can often proceed without either spouse appearing in court, particularly when a Separation Agreement has been executed. A declaration of invalidity typically requires both parties to appear before the court.
Clearer framework for financial resolution. Colorado’s dissolution process provides well-established mechanisms for equitable property division, spousal maintenance, child support, and parenting time orders. In an annulment, because the marriage is treated as never having existed, the court must impose equitable remedies to resolve financial entanglement — which can create uncertainty.
Prenuptial and postnuptial agreements remain in effect. If you and your spouse entered into a premarital or postmarital agreement, it will generally be upheld in a dissolution proceeding. In an annulment, those agreements are voided along with the marriage itself — which may or may not work in your favor.
No requirement to assign fault. Unlike an annulment, which effectively attributes a legal defect to the marriage (and by extension, potentially to one of the parties), a no-fault divorce does not assign blame to either spouse and does not require either party to make damaging accusations in open court.
Do You Need a Lawyer for an Annulment?
Whether you are pursuing a dissolution of marriage or a declaration of invalidity, legal representation matters. For an annulment in particular, working with an experienced attorney is strongly advisable. The statutory grounds under C.R.S. § 14-10-111 are specific, the burden of proof is real, and a failed annulment petition may leave you in a worse position than if you had filed for dissolution from the outset.
Beyond the legal technicalities, annulments and divorces alike involve deeply personal decisions about your financial future, your children, and your life after the marriage ends. An experienced Colorado Springs family law attorney can evaluate the specific facts of your case, advise you on which legal path is most appropriate, and help you avoid costly procedural mistakes.

Conclusion
Choosing between a dissolution of marriage and a declaration of invalidity in Colorado is not simply a matter of personal preference — it is a legal determination that depends on the specific facts of your marriage, the grounds available to you, and the financial and parenting circumstances involved. In most cases, a no-fault divorce is the faster, lower-risk, and more legally straightforward option. However, if the grounds for a declaration of invalidity genuinely apply to your situation, pursuing one may serve your interests.
