COMMENT
Scope. This section sets forth definitions that apply for purposes of the intestacy rules contained in Subpart 2 (Parent-Child Relationship).
Definition of "Adoptee". The term "adoptee" is not limited to an individual who is adopted as a minor but includes an individual who is adopted as an adult.
Definition of "Assisted Reproduction". The definition of "assisted reproduction" is copied from the Uniform Parentage Act § 102. Current methods of assisted reproduction include intrauterine insemination (previously and sometimes currently called artificial insemination), donation of eggs, donation of embryos, in-vitro fertilization and transfer of embryos, and intracytoplasmic sperm injection.
Definition of "Functioned as a Parent of the Child". The term "functioned as a parent of the child" is derived from the Restatement (Third) of Property: Wills and Other Donative Transfers. The Reporter's Note No. 4 to § 14.5 of the Restatement lists the following parental functions:
Custodial responsibility refers to physical custodianship and supervision of a child. It usually includes, but does not necessarily require, residential or overnight responsibility.
Decisionmaking responsibility refers to authority for making significant life decisions on behalf of the child, including decisions about the child's education, spiritual guidance, and health care.
Caretaking functions are tasks that involve interaction with the child or that direct, arrange, and supervise the interaction and care provided by others. Caretaking functions include but are not limited to all of the following:

Parenting functions are tasks that serve the needs of the child or the child's residential family. Parenting functions include caretaking functions, as defined [above], and all of the following additional functions:
(a) providing economic support;
(b) participating in decisionmaking regarding the child's welfare;
(c) maintaining or improving the family residence, including yard work, and house cleaning;
(d) doing and arranging for financial planning and organization, car repair and maintenance, food and clothing purchases, laundry and dry cleaning, and other tasks supporting the consumption and savings needs of the household;
(e) performing any other functions that are customarily performed by a parent or guardian and that are important to a child's welfare and development.
Ideally, a parent would perform all of the above functions throughout the child's minority. In cases falling short of the ideal, the trier of fact must balance both time and conduct. The question is, did the individual perform sufficient parenting functions over a sufficient period of time to justify concluding that the individual functioned as a parent of the child. Clearly, insubstantial conduct, such as an occasional gift or social contact, would be insufficient. Moreover, merely obeying a child support order would not, by itself, satisfy the requirement. Involuntarily providing support is inconsistent with functioning as a parent of the child.
The context in which the question arises is also relevant. If the question is whether the individual claiming to have functioned as a parent of the child inherits from the child, the court might require more substantial conduct over a more substantial period of time than if the question is whether a child inherits from an individual whom the child claims functioned as his or her parent.
Definition of "Genetic Father". The term "genetic father" means the man whose sperm fertilized the egg of a child's genetic mother. If the father-child relationship is established under the presumption of paternity recognized by the law of this state, the term means only the man for whom that relationship is established. As stated in the Legislative Note, a state that has enacted the Uniform Parentage Act (2000, as amended) should insert a reference to Section 201(b)(1), (2), or (3) of that Act.
Definition of "Relative". The term "relative" does not include any relative no matter how remote but is limited to a grandparent or a descendant of a grandparent, as determined under this subpart 2.
