As we have tried to stress time after time, procedural correctness is of the utmost importance in family law proceedings. It is imperative that family law litigants know and follow all the procedural rules which apply in their case, because even a single procedural misstep can completely alter a given situation. We have seen cases, here on our blog, for example, in which knowledge and understanding of procedure had a transformational impact for certain litigants; litigants who failed to follow certain procedural rules ended up losing otherwise winnable cases. This is something which we have seen repeatedly. Of course, understanding litigation procedure in family law is not an easy task, and so a capable family law attorney is highly recommended.

In the case of Augustine v. Wolf (2024), a father filed a motion to preclude evidence in a custody modification hearing which was used in a previous hearing on a final protective order. The question was whether the court’s determination in the protective order case collaterally estopped the presentation of the same facts and circumstances in the custody hearing. Let’s review the details of this case.  

Facts of the Case

The parents in this case had one child, known as “B.” in the context of litigation. The child was born in 2017, and by 2018 the parents had already developed a custody arrangement following their separation. The parents initially agreed to joint physical and legal custody, but the mother subsequently claimed that she found evidence of sexual abuse against B. by the father. In response to the mother’s allegations regarding sexual abuse, the court granted a temporary protective order, and also appointed a professional investigator to confirm or disconfirm the allegations.

 

Although the investigator’s report indicated that there was evidence of abuse, the court ultimately denied the petition for a permanent protective order during a hearing in 2021. The reason for this denial was the court’s reliance on alternative information presented at the hearing, including a medical examination report.  

The mother then filed a petition to modify the custody arrangement. The father, as mentioned, filed a motion to block the presentation of certain evidence used in the previous hearing on the permanent protection order, arguing that the principle of collateral estoppel applied in this situation. More exactly, the father argued that the court’s denial of the protection order meant that the court was now unable to find that he had ever committed sexual abuse, as the evidence used in that case must not have supported that conclusion. The mother argued that the court was still able to assess and weigh evidence presented in the protective order hearing for the purpose of making an independent determination in the custody modification hearing. The mother lost at the trial court level and then appealed.

Ruling & Post-Ruling Discussion

The appellate court determined that the trial court had erred in its determination that the effect of the protective order ruling was to preclude the court from considering certain evidence in the custody modification hearing. Although the principle of collateral estoppel can be invoked in certain contexts in family law – such as two proceedings of the same type – in this case, the two proceedings were wholly distinct and dissimilar, and the principle of collateral estoppel could not be used to preclude evidence from being used again.  

Again, as we discussed, this case highlights the importance of carefully understanding procedural rules in family law litigation, as well as the procedural concepts which are often used in such litigation. The father incorrectly interpreted the principle of collateral estoppel and this ended up causing a substantial waste of time and energy.
