Child Custody Between Parents in New York (DRL § 70): How a Court Decides

When two parents cannot agree on where the children live and who makes the decisions, New York lets either parent ask a court to decide. The case is built around one standard, the best interests of the child, and neither parent walks in with an automatic advantage.

A lot of parents assume the law tilts toward the mother, whoever earns more, or whoever stays in the house. None of that is how a New York custody case between two parents actually works.

This page covers how custody between parents works under Domestic Relations Law § 70, whether either parent has an automatic right, the difference between sole and joint custody, how a case starts, and what a court looks at.

How Does Custody Between Two Parents Work in New York (DRL § 70)?

Either parent can bring a custody case, and the court decides based on the child’s best interests. Domestic Relations Law § 70 lets a parent apply to the court for custody of a child, and it directs the court to decide as the child’s best interests require. There is no formula and no default split of time. The court weighs the family’s actual circumstances and crafts an arrangement for that child.

The same best-interests standard applies whether the case is in the matrimonial part of the Supreme Court as part of a divorce, or in the Family Court as a standalone custody petition.

Does Either Parent Have an Automatic Right to Custody in New York?

No. Domestic Relations Law § 70 is explicit that neither parent has a prima facie right to custody over the other. Mother and father stand on equal footing as a starting point, and the court does not favor a parent based on gender, earnings, or who currently occupies the family home.

What tips a custody case is not status but substance: which parent has been doing the day-to-day parenting, which home offers the child stability, and which parent better supports the child’s relationship with the other. A parent who assumes the law already favors them and coast on that assumption can be in for a hard surprise.

What Is the Difference Between Sole and Joint Custody Between Parents in New York?

It comes down to decisions and living arrangements. Custody has two parts, legal and physical, and each can be sole or shared:

• Sole legal custody: one parent makes the major decisions about education, health, and religion.
• Joint legal custody: both parents share those major decisions, which works best when they can communicate.
• Physical (residential) custody: which parent the child primarily lives with, while the other has parenting time.

A common New York arrangement is joint legal custody with one parent having primary physical custody. Where the parents cannot communicate at all, or where there is a history of family violence, a court may decide that joint legal custody is not workable and award sole legal custody instead.

How Does a Parent Start a Custody Case in New York?

By filing a custody petition. A parent files in the Family Court, or raises custody within a divorce in the Supreme Court, asking the court to set legal and physical custody and a parenting schedule. The other parent is served and the case proceeds, often with temporary arrangements early on while the matter is litigated.

In a contested case, the court may appoint an attorney for the child, and may order a forensic custody evaluation. Our NYC custody attorneys handle the filing and the early positioning, because the temporary arrangements set at the start can shape what feels normal by the time the case is decided.

What Does a New York Court Look At When Two Parents Both Want Custody?

The whole record of each parent’s relationship with the child. A court weighs which parent has been the primary caretaker, the stability each home offers, each parent’s ability to meet the child’s needs, each parent’s willingness to foster the child’s bond with the other parent, any history of domestic violence, and, depending on age and maturity, the child’s own preferences.

These factors are supported by evidence, school and medical records, calendars, and messages that show who handles parenting, and the testimony of people who have seen it firsthand. Our NYC custody attorneys build that record from the start, because a custody case between two parents is decided on the day-to-day reality, not on either parent’s say-so.

How Our NYC Custody Attorneys Build a Parent’s Custody Case in New York

Custody is proven, not asserted. Our NYC custody attorneys gather the caretaking record, prepare the client for the attorney for the child, and any forensic evaluation, and present a parenting plan that puts the child’s stability first. We develop the evidence that shows the court who has been doing the work and what arrangement serves this child.

We prepare each custody case as if a judge and the attorney for the child will examine every day of the schedule, because in a contested case, they often will.
