Match IDs are sent via a third party service. We cannot accurately track if a Match ID is successfully received by your co-parent.
However, we do not require your co-parent to receive a Match ID in order to sign up. They can visit TalkingParents.com and sign up without a Match ID.
If you want to seek a court order that requires your co-parent to use TalkingParents, or if you think your co-parent is acting in violation of a court order, we recommend you consult with an attorney or the court itself to find out your options.
