1. Consent by a woman, and a man who intends to be a parent of a child born to the woman by assisted reproduction, must be in a record signed by the woman and the man. This requirement does not apply to a donor.
2. Failure by a man to sign a consent required by subsection 1, before or after birth of the child, does not preclude a finding of paternity if the woman and the man, during the first two years of the child's life, resided together in the same household with the child and openly held out the child as their own.
