Domestic Partners
Domestic partners are two people who have signed an affidavit swearing that they are:

  • Are in a relationship of mutual support, caring, and commitment and intend to remain in such a relationship
  • Are each other's sole domestic partner
  • Are both at least 18 years of age and competent to contract
  • Share a life and home together
  • Are not related by kinship closer than would bar marriage in the State of Colorado
  • Are not married

Domestic Partners do NOT have to reside in the City of Boulder

Requirements for registration
The following steps are used by the City Clerk in registering domestic partners:

  • Both parties must be present
  • Picture identification card is required from both partners (i.e., driver's license, passport, military id)
  • Proof of same address (i.e., driver's license, lease agreement, joint mortgage, joint checking account, joint vehicle title, utility/phone bill delivered to each at same address
  • Registration fee is $25, payable at the time of registration (cash in the exact amount or check payable to the City of Boulder)

Providing for confidentiality and public information requirement
The Clerk's Office will record information from all Domestic Partnership registrations in the database which will become part of the public record.  Registrants,however,  have the option to request that names and year of birth not appear in the database

Terminate a Domestic Partnership
A Domestic Partnership may be terminated when:

  • One of the partners dies.
  • No longer are in a committed relationship or share a common household.
  • The partners no longer meet one or more of the requirements included in the affidavit for domestic partnership.
  • Notice of Termination is submitted to City Clerk of Boulder with the termination fee of $25.
  • Notice of Termination and fee may be mailed to: City Clerk's Office, PO Box 791, Boulder, CO  80306

The notice of termination form (including certificate number if possible), naming the partners and stating that the partnership has ended must be signed and dated by at least one partner. If only one partner signs, that partner must provide evidence (certified mail receipt) that they have attempted to notify the other partner of the termination of the partnership.

Legal Rights and Responsibilities
Domestic partnership registration is voluntary, and does not create any new or different legal rights or responsibilities. The City of Boulder is not able to provide you with any legal advice concerning your partnership, and you may wish to consult an attorney for such advice. A domestic partnership does not create a "common law marriage" and may be evidence that no common law marriage has occurred. It does not create a joint venture or partnership or create any other legal rights between the partners or relating to any third partner. However, it may be used as evidence that an intimate relationship existed between the parties. 

Because domestic partnership does not provide for many things covered by legal marriage, you should consult an attorney and make arrangements for a number of matters, including, but not limited to, wills, power of attorney, medical matters or tax implications.
