In Texas, proving alcoholism in custody cases requires evidence. The following are some of the criteria used to establish this:
* Obtaining a medical opinion that alcohol has caused physical or psychological harm to the child;
* Showing legal history of DUI convictions and/or other related criminal activities;
* Presenting testimonies from family members and friends about drinking habits. Additionally, courts may consider if parental responsibility is affected by excessive drinking. It is important to note that all pieces of evidence must be documented and presented in court for consideration.
