Common law marriage has been around for over 150 years in the United States. Common law marriage actually has its roots in Medieval times. Here, due to the lack of roads and access to transportation, justices of the peace and clerks of the law were not able to travel to marry couples. While a marriage is a legal union between two people, a common law marriage is a marriage without the formal ceremony and marriage license. As simple as this sounds, common law marriage is a bit more complicated.


Common law marriage is characterized by four common requirements:

  1. You must be living together.
  2. You both must be legally allowed to be married, or have the “capacity to marry.” This means both parties must be 18 years old, be of sound mind, and not be legally married to someone else.
  3. Both parties must intend to get married.
  4. Both parties must represent themselves to others as a married couple. Some signs of this are having the same last name, having joint bank accounts and/or loans, filing joint tax returns, and referring to each other as “husband,” “wife,” or “spouse.”

Not many states recognize common law marriage and some have banned common law marriage that used to recognize them.


Colorado is one of the few states that does recognize common law marriages. Here, a common law marriage is recognized if both parties are over 18, live as a married couple, and assume a marital relationship.

Simply living together does not constitute a marriage, even if it’s for decades. The amount of time a couple is together is inconsequential in the eyes of the state of Colorado. You must agree to be married and hold yourself as married to be common law, while living together.

One main problem of common law marriage is proving that you are actually married and the burden of proof falls on the couple. A court would need to conduct a hearing to determine the issue where the court will decide based on the facts presented and the credibility of the evidence. Judges scrutinizes these cases closely, making sure common law marriages are not self-serving, meaning the couple only claims common law marriage when it is convenient for them and claim single otherwise.

If you are claiming common law marriage, you’d better have documents and a lot of family and friends to back up your claim. This is to prevent fraud. There are many reasons one may claim to be in a common law marriage, primarily for economic advantages. These include health insurance, joint gym membership, educational purposes, social security benefits, and life insurance purposes. Colorado does recognize same-sex common law marriages. On the flip side, it can be hard to get on your partner’s health insurance if you are only common law married. It may behoove you to make your union formal in order to eliminate the hassle of the legal obligation of proving your common law marriage.


On the flip side, some couples were being classified as being common law married who did not want to be, and then had to go through a legal divorce process when they separated. Furthermore, the law was antiquated in modern society. Transportation to a courthouse is generally not a problem for the majority of the population. Common law was just one more thing the often overburdened courts had to process, and since people are perfectly capable of making a marriage decision, it seems a waste of precious tax-payer dollars to process.


Once a common law marriage is established, it’s just as binding as a legal marriage. You must be granted a legal divorce and go through legal divorce proceedings just like any other married couple if you wish to separate, or a partner dies, this is grounds for separation as well. If a partner dies and a common law marriage hasn’t been established previously, you’ll have to prove one existed. This applies only to those few states that recognize common law marriage.
