The short answer? Absolutely.
Before we dive into the long answer, it’s key to understand the general types of child custody.
The type of custody arrangement enacted depends on what the court must prioritize above all else: the best interests of the child.

Now, there’s no precise formula for determining what’s in a child’s best interests, but judges are often directed to consider a variety of factors, such as:
This list of factors varies from state to state.
But where does alcohol abuse come into play?
Unfortunately, substance abuse is a common issue impacting children in the US – around 1 in 8 reside with a parent who has a substance use disorder.1 One study found that 12.1% of kids in the US live with at least one parent who, specifically, has alcohol use disorder. Consequently, addiction and alcohol abuse are explicitly mentioned in many custody clauses nationwide.2
However, even if a state’s clauses don’t directly mention substance abuse, judges usually consider it. If one parent is struggling with alcohol issues, it’s likely to make them question how suitable that parent is for creating a stable environment for the child. This affects what’s best for the child.
So, in custody cases involving alcohol across the US, being sober is generally seen as being dependable and capable in the eyes of the court.
Something else to note: Family courts often see regular parenting time as vital for a child’s well-being. When there’s clear evidence of a parent struggling with alcohol abuse, judges usually work on ways to keep kids safe during visits rather than cutting off all parenting time, even in cases of sole custody.
What prompts a judge to address alcohol use or require alcohol testing in custody proceedings?
Often, a parent only needs to report the presence of a drinking issue. In certain states, proof of an alcohol abuse disorder must additionally be provided.
Either way, gathering evidence is a wise move – the more, the better – and can only serve to bolster your case.

As a remote alcohol monitoring service, we’d be remiss not to mention the powerful evidence it can provide in custody cases.
Unlike traditional lab tests, remote alcohol monitoring relies on connected breathalyzers to check a person’s BAC (blood alcohol content). No need for parents to rush to a specific place for a test – breathalyzer tests can be taken anywhere.
More importantly, a breathalyzer test shows if someone had alcohol at a specific moment rather than just at “some point” over time. This is crucial in custody cases to see if a parent is drinking, for example, when they’re with their child.
Your co-parent gets text reminders, either regularly or randomly, to do a breathalyzer test. Each test is logged with the date, time, and place. BACtrack View even lets you download test records as neat PDFs for court. If there’s a pattern of positive or missed tests, it could suggest a drinking issue, which can be used as evidence in custody matters.

You can obtain records of alcohol-related convictions, like DUIs or public intoxication charges, to show a pattern of substance abuse.
To elaborate further on DUIs: The circumstances under which a parent received one can influence a custody case differently. For example, multiple DUIs will likely demonstrate a pattern of problem drinking (as opposed to a single DUI). Furthermore, the context of a DUI – the parent’s recorded BAC level, whether the child was in the vehicle, etc. – can impact the outcome of a custody case.4
When friends or family share firsthand experiences of a parent’s behavior while drinking, it can shed light on the situation.
Doctors can note down what they find during exams or tests that point to a parent having issues with alcohol.
Looking at termination papers or other work documents can reveal how a parent’s drinking affected their job or ability to keep steady employment.
A judge may request an evaluation by a substance abuse professional to gain insight into a parent’s alcohol consumption and its potential impact on their parenting abilities.
Financial records can indicate a parent’s frequent or significant alcohol expenditures.

A parent’s social media content, or posts involving them, could reveal signs of intoxication or alcohol use.
Incoherent communications can illustrate a parent’s conduct while under the influence or seeking alcohol. These may include voicemails, texts, emails, and video calls.
Court-ordered reports evaluate a parent’s suitability for custody, potentially referencing substance abuse or dependency if observed.
In situations where obtaining direct proof is challenging, a private investigator can aid in collecting evidence of alcohol consumption.
After gathering evidence of alcohol abuse, it’s essential to know what the possible outcomes could be for custody battles. For instance, if a parent demonstrates ongoing alcohol abuse, this could negatively impact their chances of gaining custody. In some cases, courts may include stipulations such as a sobriety clause in the parenting plan, requiring the parent to maintain sobriety as a condition for visitation or custody. Understanding these potential legal ramifications can help in preparing a strong case that prioritizes the child’s welfare.
Depending on the severity and frequency of a parent’s drinking issue, a judge may order:

In conclusion, navigating a custody case where alcohol use is a concern is undoubtedly challenging. But not insurmountable.
It’s crucial to approach this process with a supportive mindset, understanding that the ultimate goal is the well-being and safety of the children involved. Three key takeaways:
Proving sobriety in a custody case can be critical.
