C.R.S.
Section 19-4-106
Assisted reproductive procedures
(1)
If, with the consent of another intended parent, an intended parent consents to become pregnant through an assisted reproductive procedure, the intended parent who does not give birth is treated in law as the natural parent of the child conceived. The consent of both the intended parent who will give birth and the other intended parent must be in writing and signed by each such party, except as provided in subsection (5) of this section. This subsection (1) does not apply to a child conceived pursuant to a surrogacy agreement pursuant to article 4.5 of this title 19.(2)
A donor is not a parent of a child conceived by means of an assisted reproductive procedure, except as provided in subsection (3) of this section.(3)
and (4)(Deleted by amendment, L. 2022.)(5) Failure of the intended parent to sign a consent required by subsection (1) of this section before or after the birth of the child does not preclude a finding that the intended parent is the parent if the court finds by clear and convincing evidence that, prior to the conception of the child, the parent who gave birth and the intended parent had an oral agreement that both would be parents of the child and that the child was conceived through an assisted reproductive procedure.(7)
Intentionally left blank —Ed.(a)
If a marriage or civil union is dissolved before placement of eggs, sperm, or embryos, the former spouse or civil union partner is not a parent of the resulting child unless the former spouse or civil union partner consented in a record that if the assisted reproductive procedure were to occur after a dissolution of marriage or civil union, the former spouse or civil union partner would be a parent of the child.(b)
The consent of a former spouse or civil union partner to assisted reproduction may be withdrawn by that individual in a record given to the parent who agreed to give birth to a child conceived by an assisted reproductive procedure at any time before placement of eggs, sperm, or embryos.(8)
If a spouse or civil union partner dies before placement of eggs, sperm, or embryos, the deceased spouse or civil union partner is not a parent of the resulting child unless the deceased spouse or civil union partner consented in a record that if assisted reproduction were to occur after death, the deceased spouse or civil union partner would be a parent of the child.(9)
This section does not apply to the birth of a child conceived by means of sexual intercourse.(10)
For purposes of this section, “donor” is defined in section 19-1-103.
