Legal Separation vs. Divorce in Colorado: How to Decide
Legal separation and divorce accomplish many of the same things — they divide property, establish parenting arrangements, set child support, and determine spousal maintenance. The difference is that after a legal separation, you’re still technically married. Whether that distinction matters depends entirely on your circumstances.
The Core Difference: What "Legal Separation" Actually Means in Colorado
In Colorado, both legal separation and divorce are handled in the same court, require the same filings, and resolve the same issues — property division, parenting arrangements, child support, and spousal maintenance. The defining difference is marital status when it’s over.
After a divorce, you are legally single and free to remarry. After a legal separation, Colorado law still considers you married — even if you live separate lives, maintain separate finances, and have a complete court order governing every aspect of your separation. You cannot remarry without first converting the separation to a divorce.
For many couples, this distinction is purely technical. For others — those with healthcare coverage tied to a spouse’s employer plan, those who observe religious beliefs that prohibit divorce, or those who are approaching the 10-year Social Security threshold — it’s everything.
How the Process Compares
The procedural path for both options is nearly identical in Colorado. Both are filed in district court, both require the same financial disclosures, both go through the same 91-day waiting period, and both result in binding court orders. The court resolves the same issues in both proceedings.
| Category | Legal Separation | Divorce |
|---|---|---|
| Legal Status | Still legally married | Marriage legally dissolved |
| Remarriage | Not permitted without conversion to divorce | Permitted immediately after decree |
| Healthcare Coverage | Spouse may remain on partner’s employer plan | Coverage ends at divorce; COBRA or marketplace required |
| Federal Taxes | Can still file jointly (if both parties agree) | Must file as single or head of household |
| Property Division | Divided by court order (same as divorce) | Divided by court order |
| Social Security | Marriage duration clock continues running | Clock stops at divorce date |
| Conversion | Can be converted to divorce by either spouse | Final — cannot be reversed |
When Legal Separation Makes Sense
Legal separation is not a halfway measure or a trial divorce. It is a full legal proceeding with a binding decree. Some couples genuinely benefit from this option:
Healthcare coverage. If one spouse depends on the other’s employer-sponsored health insurance, divorce ends that coverage immediately. A legal separation keeps the marriage intact on paper, which may allow coverage to continue — though this depends on the specific plan. Confirm directly with the insurer before making this decision.
Religious beliefs. For couples whose faith prohibits divorce, legal separation allows them to legally divide their lives without violating a deeply held conviction. The court order provides all the same legal protections a divorce decree would.
Social Security benefits. A divorced spouse may claim up to 50% of their ex-spouse’s Social Security benefit, but only if the marriage lasted at least 10 years. If you’re at year 8 or 9, remaining legally separated — rather than divorcing — preserves the ability to reach that threshold.
Uncertainty about finality. Colorado allows a legal separation to be converted to a divorce, but not the other way around. Some couples separate legally while leaving the door open. That said, if both parties eventually want to reconcile, a legal separation can be dismissed.
When Divorce Is the Better Choice
For the majority of couples, divorce is the more practical option. Here’s when it’s clearly the right path:
You want to remarry. Legal separation blocks you from entering a new marriage. If moving forward with a new relationship is important, divorce provides that clean break.
There’s no healthcare or Social Security reason to stay married on paper. Without a concrete benefit to maintaining legal marital status, separation adds complexity without adding value.
You want clear finality. A divorce decree is final. It removes ambiguity about your legal status and simplifies everything from filing taxes to naming beneficiaries on new accounts and insurance policies.
The relationship is over and both parties are ready. Some couples are tempted to separate legally as a compromise. But if the marriage is over — practically and emotionally — divorce is typically the cleaner legal resolution. Our experienced divorce attorneys can help you evaluate which path is right for your situation.
The Tax and Financial Implications of Each
Filing taxes. Legally separated spouses in Colorado may still file federal taxes jointly if both parties agree and their tax situation benefits from joint filing. Once divorced, you must file as single or head of household. Depending on income levels and deductions, this change can meaningfully affect your tax liability. Consult a tax professional alongside your divorce attorney to model the difference before finalizing anything.
Retirement accounts. Both divorce and legal separation allow the court to issue a Qualified Domestic Relations Order (QDRO) dividing retirement accounts without triggering tax penalties. The process is the same under either option.
Estate planning. Legal separation does not automatically revoke beneficiary designations on retirement accounts, life insurance policies, or payable-on-death accounts. If you complete a legal separation without updating these designations, your separated spouse could still inherit assets upon your death. Divorce triggers automatic revocation of certain designations under Colorado law, though not all. In both cases, updating your estate plan immediately after the proceeding is critical.
Social Security threshold. As noted, if you’re within two years of the 10-year Social Security marriage threshold, the financial benefit of remaining legally married on paper may be significant and worth calculating carefully.
What Happens to Property, Support, and Custody
Colorado courts handle property division, spousal maintenance, child support, and parenting time identically in both separation and divorce proceedings. The same equitable distribution standard applies. The same child support guidelines apply. Parenting plans are treated no differently.
The key practical distinction comes after the proceeding ends. In a legal separation, because you remain legally married, marital property that has not been addressed in the separation decree may still be treated as jointly owned. Any assets acquired after the decree may also raise questions about their marital status. Divorce cleanly cuts the marital estate at the date of the decree.
For parenting arrangements, neither option is superior — Colorado courts focus entirely on the best interests of the child regardless of whether the underlying proceeding is a separation or divorce.
How to Convert a Legal Separation to Divorce in Colorado
Colorado law allows either spouse to convert a legal separation to a divorce. Under C.R.S. § 14-10-120, either party may file a motion to convert the decree of legal separation into a decree of dissolution of marriage at any time after the separation has been in effect for six months.
The conversion is typically straightforward — the court generally does not re-litigate property division, support, or parenting arrangements unless there is a compelling reason to do so. The terms of the original separation decree usually carry forward into the divorce decree.
This creates a practical option: some couples enter legal separation intentionally as a step, knowing they may convert later. Others enter it as a permanent arrangement. The flexibility exists, but it’s worth noting that the reverse — converting a divorce back to a marriage — is not possible under Colorado law. If you reconcile after a divorce, you’d need to legally remarry.

Frequently Asked Questions
Can I remarry after a legal separation in Colorado?
No. After a legal separation in Colorado, you are still legally married. You cannot remarry unless you first convert the legal separation to a divorce. Under Colorado law, either spouse can file to convert the decree of legal separation to a dissolution of marriage after the separation has been in effect for six months.
How long does a legal separation take in Colorado?
The timeline for legal separation in Colorado is essentially the same as divorce. Colorado law requires a minimum 91-day waiting period from the date of service before a decree can be entered. Uncontested separations can be finalized relatively quickly after that period. Contested separations involving disputed property or parenting arrangements take longer, depending on the complexity of the issues and court scheduling.
Is legal separation cheaper than divorce in Colorado?
Not inherently. The cost of both proceedings is driven primarily by whether the case is contested. An uncontested legal separation can be just as affordable as an uncontested divorce. A contested separation — where the parties dispute property, support, or custody — will incur similar attorney fees to a contested divorce. If there is a realistic possibility you’ll convert to divorce later, that future cost is worth factoring in as well.
Can one spouse convert a legal separation to divorce without the other's consent?
Yes. Under C.R.S. § 14-10-120, either party to a decree of legal separation may file a motion to convert it to a decree of dissolution of marriage. The requesting spouse does not need the other party’s agreement. This is a meaningful distinction: if one spouse later decides they want a full divorce, they can pursue that unilaterally after the six-month period has elapsed.
Does legal separation affect my health insurance in Colorado?
It depends entirely on the health plan. Many employer-sponsored health insurance plans define eligibility based on legal marital status. Since a legal separation leaves you technically married under Colorado law, some plans will continue coverage for a separated spouse. However, plans vary significantly, and some may treat a court-ordered separation as a qualifying life event that triggers the end of coverage. You must confirm directly with the insurer or plan administrator — do not assume coverage continues without verifying.
What is the difference between a legal separation and just living separately?
Simply living apart — even for years — has no legal effect in Colorado. You remain fully married in every legal sense. Colorado does not grant common law divorce based on separation periods. A legal separation, by contrast, is a formal court proceeding that results in a binding decree dividing property, establishing parenting arrangements, and setting support obligations. It is a legally enforceable order. Informally living separately is not.
Does Colorado recognize legal separation from another state?
Generally yes, with some caveats. Colorado courts will typically recognize a legal separation decree from another state under the full faith and credit clause of the U.S. Constitution. However, if you wish to convert a legal separation from another state into a Colorado divorce, you must establish residency in Colorado (at least 91 days) and may need to petition the court. The specifics depend on how the original separation was structured and which state issued it. An attorney can advise on the particulars of your situation.
