Second, kindly provide documentation that he "refused" to sign the agreement
I know people like to say "An absence of evidence is not evidence of absence." I know it's pithy and fun to say, but it isn't true.
For instance. If someone is claiming another party agreed to the terms of a contract but they are unable to produce a signed contract, that's evidence that no agreement ever took place.
The thing of it is though, I don't believe I actually need to explain that to you.
Except that in a court of law, it is not "evidence that no agreement ever took place". We have evidence that agreement took place because we have his actions. There are also more than a year's worth of emails and texts that the court had access to. It probably didn't help the plaintiff's case, either, that his main legal argument is that he's allowed to change his mind in spite of his agreement. If there wasn't an actual agreement, why would he need to legally verify a right to change his mind?
You and others here keep going back to the "Informed Consent" document, and stopping there. Not even the Plaintiff is doing that.
It appears to me that, given the conflicting nature of the "Informed Consent" document, the unsigned but acted on "Co-Parenting" contract and the various emails and texts after, the judge proceeded to the "balancing approach". I know that you think it is black and white cut and dried, but not even the Plaintiff believes that.
This is personal opinion, but I would also note that in the cases I've been reading as a result of this case, the only times a court relied on an "Informed Consent" document as binding is when
(1) the document was far more detailed than the OP one appears to be. For instance, in one case the basic language said both parties had to agree, but then it also said in the event of a divorce/separation/disagreement, the parties had to write in the name of the person (& it could have been a third party or an appointed mediator or the court) who would make the final determination. They hand wrote the wife's name, and both initialed it. Contrast this situation wherein there was no provision in the "Informed Consent" document in the event of a divorce/separation or disagreement. I think a court could view a detailed, fill-in-the-blank document as a better indication of an actual agreement than a boiler-plate "Informed Consent" superseded by a visit to the attorney's office and a completed draft of a co-parenting agreement.
(2) Abiding by the "Informed Consent" document does not result in one party not being able to have their own biological child.
And I would again emphasize that it is the Plaintiff insisting he had the right to change his mind regardless which agreement anyone found valid. Do you agree that he had the right to change his mind right up to the point of implantation?
