What is Collateral Information in Family Court | New Directions Assessments

Learn why collateral information is an important part of family court assessments and how it helps evaluators provide objective recommendations.

Family court cases are often some of the most challenging legal situations a parent can face. Unlike many other court proceedings, family court decisions directly affect the well-being, safety, and future of children. Because of this, judges and attorneys rely on thorough, objective assessments to help them make informed decisions.

One of the most important parts of a quality family court assessment is the review of collateral information. While many people expect an assessment to consist primarily of an interview with the individual being evaluated, experienced evaluators know that interviews alone rarely tell the complete story.

What Is Collateral Information?

Collateral information is information gathered from sources other than the person being evaluated. It helps the evaluator verify facts, better understand the circumstances of the case, and develop recommendations that are based on multiple sources of information rather than self-report alone. Whether an evaluator is completing a family court mental health assessment or a family court drug and alcohol assessment, collateral information and relevant records are often essential to developing balanced, objective recommendations. Professional standards for family court evaluations emphasize looking beyond self-report to ensure opinions are based on the fullest picture available.

Depending on the circumstances, collateral information may include:

  • Interviews with parents or caregivers
  • Information from other family members
  • Medical or mental health records
  • School records
  • Court documents
  • Police reports
  • Prior evaluations
  • Relevant legal history
  • Other individuals who have direct knowledge of the family situation

Every case is different, and the types of collateral information reviewed will depend on the specific concerns before the court.

Why Isn’t the Interview Enough?

In many types of assessments, evaluators rely heavily on interviews and standardized testing. While those tools are valuable, family court cases often involve situations where multiple people have very different perspectives.

For example:

  • One parent may believe the other parent poses significant safety concerns.
  • Another parent may believe the allegations are exaggerated or inaccurate.
  • Family members may have conflicting accounts of important events.

Because emotions can run high during custody disputes, relying solely on one person’s account may not provide the complete picture. Reviewing collateral information allows the evaluator to compare information from multiple sources and develop a more objective understanding of the issues involved. Guidance for custody evaluations consistently encourages evaluators to consider information from collateral sources and document review as part of their assessment process.

Why Does Collateral Information Matter?

Family court professionals have an important responsibility: helping the court determine arrangements that serve the best interests of the child.

Collateral information can help:

  • Provide additional context surrounding allegations or concerns
  • Verify or clarify information shared during interviews
  • Identify patterns that may not be apparent through self-report alone
  • Reduce the influence of bias from any one individual
  • Support fair, balanced recommendations for the court

The goal is not to prove one parent “right” or “wrong.” Rather, it is to gather enough reliable information to assist the court in making informed decisions.

Does Every Assessment Include Collateral Information?

Not necessarily.

Many standard mental health or substance use assessments rely primarily on clinical interviews, questionnaires, and standardized assessment tools. These evaluations may be entirely appropriate for other situations but may not include the extensive review of collateral information that family court cases often require.

Because gathering and reviewing collateral information takes additional time and professional judgment, comprehensive family court assessments are generally more involved than traditional clinical evaluations.

In some family court cases, concerns about alcohol or substance use may also play a role in the evaluation process. If those concerns are part of your case, you may also find our article, “Why Domestic Court Might Require a Parent to Get a Clinical Alcohol and Drug Assessment,” helpful.

Common Questions About Family Court Assessments

How long does a family court assessment take?

The timeline varies depending on the complexity of the case, the number of individuals involved, and the amount of collateral information that must be reviewed. Cases involving extensive records or multiple interviews generally require more time than a standard clinical assessment.

How much does a family court assessment cost?

Costs depend on the scope of the evaluation and the amount of collateral information that must be gathered and reviewed. Before scheduling an assessment, it is helpful to discuss the expected process, estimated timeline, and associated fees with the evaluating provider.

Choosing an Assessment Provider

If your attorney, guardian ad litem (GAL), or the court has recommended a family court assessment, consider asking whether the evaluator incorporates collateral information into the assessment process.

A thorough evaluation should look beyond a single interview and carefully consider relevant information from multiple sources when appropriate. This approach helps provide the court with a more complete understanding of the issues involved and supports fair, objective recommendations.
