Separate vs. Marital Property: What Happens to Property You Owned Before Marriage?

Trista Price
Denver Family Law Attorney Dividing property is often one of the most challenging parts of a Denver divorce, especially when one spouse brought a home, investments, a business, retirement savings, or other valuable assets into the marriage. Many clients believe that anything they owned before getting married will automatically stay theirs. While Colorado law does protect some premarital property, things can get complicated if that property grows in value during the marriage, is refinanced, put into both spouses’ names, or mixed with marital funds. The difference between separate and marital property can affect how much of an asset is protected and how much might be divided in a divorce. We carefully review when the property was acquired, how it was managed during the marriage, and how its value changed to decide what part may be divided.

Property Owned Before Marriage Is Generally Separate Property

Colorado’s property division law is found primarily in C.R.S. § 14-10-113. Under the statute, a Colorado court must first set aside each spouse’s separate property and then divide the marital property in proportions the court considers just after weighing the statutory factors.  Property acquired before marriage generally starts as separate property. If one spouse owned a house worth $300,000 before getting married, for example, the premarital value of that house may ordinarily be treated as that spouse’s separate property. This rule also applies to bank accounts, investments, retirement accounts, business interests, land, vehicles, and other things you owned before marriage. Figuring out what these were worth around the time you got married is important, since that value helps decide what counts as separate property later.

An Increase in Value During Marriage Can Become Marital Property

Owning an asset before marriage does not necessarily mean every dollar associated with that asset remains separate. Under C.R.S. § 14-10-113(4), property acquired before marriage is treated as marital property to the extent its present value exceeds its value at the time of the marriage.  Colorado appellate courts also recognize that if separate property increases in value during the marriage, that increase can be considered marital property and divided. For example, if one spouse had an investment account worth $200,000 before marriage and it grows to $500,000 by the end of the marriage, the original $200,000 is usually separate property. The $300,000 increase may be considered marital property. This rule can have major consequences in longer marriages and in divorces involving real estate, privately held companies, investments, stock portfolios, or other assets that increased substantially in value.

Premarital Homes Can Have Both Separate and Marital Components

A house owned before marriage is a common source of disagreement. The home’s premarital value may be separate property, but appreciation during the marriage can create a marital component. This can happen even when title remains solely in the name of the spouse who originally purchased the property. For example, if a Denver home was worth $400,000 at the time of marriage and is worth $650,000 when the property is valued for divorce, the increase may become an important part of the marital estate analysis. Mortgage payments, renovations, market appreciation, refinancing, and the source of money used to maintain or improve the property can all become relevant factual issues. We therefore look beyond the name appearing on the deed. Colorado law specifically provides that property acquired during marriage is generally presumed marital regardless of whether it is held individually or jointly, subject to the statutory exceptions. C.R.S. § 14-10-113(3). 

Commingling Can Make Tracing More Difficult

Separate property sometimes becomes mixed with marital property during the marriage. A spouse might deposit premarital savings into a joint account, use inherited funds toward a jointly owned home, or move separate investments among several accounts. These transactions do not necessarily mean the entire asset automatically becomes marital, but they can make its separate character harder to establish. Documentation can become critical. We may examine account statements, closing documents, tax returns, deeds, investment records, business records, loan documents, and other financial evidence to trace an asset back to its separate-property source. The longer funds have been mixed together, the more detailed this analysis may become. A clear financial record can make a significant difference when the classification of substantial assets is disputed.

Gifts, Inheritances, and Property Exchanged for Separate Assets

Colorado law also excludes several categories of property from the definition of marital property. Under C.R.S. § 14-10-113(2), exceptions include property acquired by gift, bequest, devise, or descent; property received in exchange for premarital property or certain gifted or inherited property; property acquired after a decree of legal separation; and property excluded through a valid agreement between the spouses.  These classifications matter because an asset does not necessarily become marital simply because it was received while the spouses were married. An inheritance received by one spouse during the marriage, for instance, can remain separate property. However, appreciation associated with separate property may still require additional analysis under Colorado law.

Colorado Uses Equitable Division, Not Automatic 50/50 Division

Once the court identifies the marital estate, it does not simply divide everything in half automatically. Under C.R.S. § 14-10-113(1), courts divide marital property in proportions they consider just. Factors include each spouse’s contribution to acquiring marital property, including contributions as a homemaker, the value of property being set aside to each spouse, each spouse’s economic circumstances, and increases, decreases, or depletion of separate property during the marriage. Separate property can therefore affect the larger financial picture even when that particular asset is not itself divided. For us, the central question is rarely just, “Whose name is on the property?” We examine when the asset was acquired, its value at the beginning of the marriage, what happened to it during the marriage, and its value when the marital estate is divided. That analysis can be especially important when substantial real estate, investments, retirement assets, or business interests are involved.

Frequently Asked Questions About Separate and Marital Property in Colorado

If We Owned a House Before Getting Married, Does Our Spouse Get Part of It?

Not necessarily, but the answer may depend on how the property’s value changed during the marriage. Under C.R.S. § 14-10-113(4), the premarital value of property can remain separate while an increase in value during the marriage may be considered marital property.  For example, if we establish that a house was worth $350,000 when the marriage began and it later became worth $600,000, the original value and subsequent increase may be treated differently. We would also want to examine mortgages, refinancing, improvements, transfers of title, and any agreements between the spouses. Establishing an accurate premarital value is often a critical part of protecting a separate-property claim.

Does Putting Our Spouse’s Name on Premarital Property Automatically Make It Marital?

A change in title can be important, but title alone does not always resolve the classification issue. Colorado property disputes are highly fact-dependent, and courts may examine the circumstances surrounding a transfer as well as the parties’ intent and financial records. If a premarital home is later placed into both spouses’ names, for example, we would want to understand why the transfer occurred and how the property was treated afterward. We would not assume that the original separate interest has necessarily disappeared without reviewing the transaction and relevant evidence. Because substantial equity can be involved, deeds and refinancing documents should be examined carefully.

What If We Cannot Prove What Our Property Was Worth When We Got Married?

This can create a significant evidentiary problem because establishing the premarital value helps determine what portion may remain separate. We may look for historical account statements, appraisals, property assessments, tax records, brokerage statements, business valuations, closing documents, retirement statements, or other records that existed near the marriage date. When exact records no longer exist, other financial evidence or professional valuation methods may sometimes help establish a supportable value. The Colorado Supreme Court’s decision in In re Marriage of Balanson illustrates the importance of proving both the separate-property interest and the amount of appreciation when determining what belongs in the marital estate. 

Is an Inheritance Received During Marriage Marital Property?

An inheritance received by one spouse is generally excluded from marital property under C.R.S. § 14-10-113(2)(a) because the statute excludes property acquired by gift, bequest, devise, or descent.  That does not mean every issue involving inherited property is simple. If inherited money is deposited into shared accounts, used to acquire other assets, or otherwise mixed with marital funds, tracing may become necessary. Appreciation associated with separate property can also create a marital component. We therefore examine both the source of the inheritance and what happened to the property after it was received.

Can Our Spouse Receive More Marital Property Because We Have Significant Separate Property?

Potentially. Colorado courts divide marital property equitably rather than under a mandatory equal-division formula. C.R.S. § 14-10-113(1) specifically directs the court to consider the value of property set apart to each spouse as well as each spouse’s economic circumstances.  A Colorado Court of Appeals decision in 2026 also emphasized that substantial separate property can be an economic circumstance the court must meaningfully consider when determining an equitable division of the marital estate. This does not mean separate property itself is simply divided between the spouses. It means the existence and value of that property can influence the court’s broader assessment of what constitutes a fair division of marital assets.
