With deep knowledge of New York family courts, we advocate for fair agreements that address practical concerns like school proximity and co-parenting logistics.

We facilitate amicable divorce resolutions through mediation and collaborative law. Our trained mediators help couples negotiate terms without court intervention, focusing on transparency and mutual benefit. This approach reduces conflict and costs while maintaining control over the outcome for families.

Questions
What types of child custody arrangements do you handle?
We handle joint custody, full custody, physical custody, and legal custody cases, ensuring agreements align with the child's best interests under New York law.
Can divorce settlements be modified after court approval?
Yes, modifications are possible for significant changes like relocation, income shifts, or custody concerns. We help clients navigate post-divorce adjustments through court petitions.
How does child support enforcement work in New York?
Enforcement includes wage garnishment, tax refund interception, and license suspension. Our attorneys pursue legal remedies to ensure consistent support payments for children's needs.
What's the difference between mediation and collaborative law?
Mediation uses a neutral third party for negotiations, while collaborative law involves direct attorney-assisted settlements. Both avoid court but differ in process structure and commitment to resolution.
How long does a typical divorce take on Long Island?
Uncontested divorces may take 3-6 months, while contested cases often last a year or more depending on court schedules and case complexity in Nassau or Suffolk County.
