16 Best Interest Factors in Maryland Custody Cases

Before October 2025, Maryland judges evaluated custody using factors from two case-law precedents — Montgomery County DSS v. Sanders (1977) and Taylor v. Taylor (1986). Different judges weighted different factors, and outcomes varied by county.

House Bill 1191 changed that. Effective October 1, 2025, Maryland codified 16 specific best-interest factors into Family Law Article Section 9-201. Judges must now evaluate every factor and document their findings in writing or on the record. No factor automatically outweighs another — the court considers the totality of circumstances.

The 16 Factors

1. Stability and Foreseeable Welfare

The child's current stability and their foreseeable health and well-being. Courts look at which arrangement minimizes disruption to the child's established routine — same school, same neighborhood, same social circle.

2. Parental Contact

The benefit of frequent, regular, and continuing contact with both parents, provided each parent demonstrates the capacity to act in the child's best interests. This factor favors arrangements that maximize the child's time with both parents.

3. Shared Responsibility

Whether and how parents who live in separate homes will share the rights and responsibilities of raising the child. Courts want a plan that shows both parents are invested in the child's daily life.

4. Key Relationships

The child's relationship with each parent, siblings, other relatives, and other significant people in their life. A custody arrangement that severs a child from a close grandparent or sibling relationship weighs negatively.

5. Conflict Protection

The child's physical and emotional security, particularly protection from exposure to parental conflict and domestic violence. Parents who fight in front of the child, use the child as a messenger, or involve the child in adult disputes hurt their case on this factor.

6. Developmental Needs

The child's physical safety, emotional security, positive self-image, interpersonal skills, and intellectual growth. Courts consider whether each parent's home environment supports healthy development.

7. Day-to-Day Needs

Education, socialization, cultural activities, religious training, food, shelter, clothing, and physical and mental healthcare. This factor examines each parent's ability to meet the practical daily needs.

8. Altruistic Co-Parenting

Each parent's demonstrated ability to place the child's needs above their own, protect the child from conflict, and maintain the child's relationships with extended family members. Courts reward parents who actively facilitate the child's relationship with the other parent.

9. Age of the Child

The child's age in relation to their developmental and scheduling needs. Infants may need more frequent transitions to maintain attachment with both parents. Teenagers may benefit from longer stretches in one home to maintain social connections.

10. Military Deployment

Any active or pending military deployment and its effect on the parent-child relationship. Maryland has specific protections to ensure a deployed parent's custody rights are preserved during service.

11. Prior Orders and Agreements

The history, compliance with, and success of any prior court orders, informal agreements, or mediation stipulations. A parent who has consistently followed existing orders demonstrates reliability.

12. Historical Caregiving Roles

Each parent's historical role in daily care — who handled school drop-offs, doctor's appointments, bedtime routines, homework. Courts examine how these roles have changed since separation.

13. Geographic Proximity

The location of each parent's home relative to the child's school, activities, and the logistical feasibility of the proposed schedule. Parents who live an hour apart will have difficulty making a 2-2-3 schedule work.

14. Co-Parenting Relationship

The parents' ability to communicate, co-parent without disrupting the child's life, and resolve future disputes without court intervention. This factor strongly influences whether the court orders joint or sole custody.

15. Child's Preference

The child's stated preference, if they are of sufficient age and maturity to express an independent opinion. Maryland does not set a specific age threshold — the judge evaluates each child's maturity individually.

16. Catch-All Factor

Any other factor the court considers relevant to the child's physical, developmental, and emotional needs. This gives judges flexibility to address unusual circumstances.

How to Prepare for a Best-Interest Evaluation

Collect evidence that addresses each factor directly. Organize school records, medical records, communication logs, overnight tracking, and documentation of your involvement in daily caregiving. Bring printed copies of text messages and emails — Maryland courts will not review evidence on personal devices.

The Maryland Custody & Parenting Plan Guide includes a Best-Interest Self-Audit worksheet that walks you through all 16 factors with space to document your evidence for each one.
