Whether one is creating or modifying a shared parenting plan, one must consider a number of issues. The following uses Ohio's Revised Code as a guide, since this is where this author practices
In order to change a shared parenting plan, the party asking the court for a change has a burden of demonstrating that the change is in the best interests of the child and that the negative effects of that change would not outweigh any supposed benefits.
R.C. 3109.04 (F)(1) lays out factors a court must consider when making or modifying a shared parenting Order. In material part it states:
. . . the court shall consider all relevant factors, including, but not limited to:
(a) The wishes of the child’s parents . . .;
(b) If the court has interviewed the child in chambers . . . the wishes and concerns of the child, as expressed to the court;
(c) The child’s interaction and interrelationship with the child’s parents, siblings, and any other person who may significantly affect the child’s best interest;
(d) The child’s adjustment to the child’s home, school, and community;
(e) The mental and physical health of all persons involved in the situation;
(f) The parent more likely to honor and facilitate court-approved parenting time rights or visitation and companionship rights;
(g) Whether either parent has failed to make all child support payments, including all arrearages, that are required of that parent pursuant to a child support order under which that parent is an obligor;
(h) Whether either parent or any member of the household of either parent previously has been convicted of or pleaded guilty to any criminal offense involving any act that resulted in a child being an abused child or a neglected child; whether either parent, in a case in which a child has been adjudicated an abused child or a neglected child, previously has been determined to be the perpetrator of the abusive or neglectful act that is the basis of an adjudication; whether either parent or any member of the household of either parent previously has been convicted of or pleaded guilty to a . . . a sexually oriented offense involving a victim who . . was a member of the family or household . . .; whether . . .any member of the household of either parent previously has been convicted of or pleaded guilty to [domestic violence]; and whether there is reason to believe that either parent has acted in a manner resulting in a child being an abused child or a neglected child;
(i) Whether the residential parent or one of the parents subject to a shared parenting decree has continuously and willfully denied the other parent’s right to parenting time in accordance with an order of the court;
(j) Whether either parent has established a residence, or is planning to establish a residence, outside this state.
(2) In determining . . . the best interest of the children, the court shall consider all relevant factors, including, but not limited to, . . . all of the following factors:
(a) The ability of the parents to cooperate and make decisions jointly,;
(b) The ability of each parent to encourage the sharing of love, affection, and contact between the child and the other parent;
(c) Any history of, or potential for, child abuse, spouse abuse, other domestic violence, or parental kidnapping by either parent;
(d) The geographic proximity of the parents to each other, as the proximity relates to the practical considerations of shared parenting;
(e) The recommendation of the guardian ad litem of the child, [if one was appointed].
No one of these factors is completely determinative. One should look these over and ask if, objectively, enough of these are in their favor.
