Case context & history

The question: How should a court account for domestic violence when distributing marital property?

Outcome / stage: Equitable-distribution decision after trial.

The published opinion describes the court’s findings and analysis in that divorce case. It does not establish how another court would decide a different family’s circumstances.

History coverage: Subsequent proceedings and appellate history have not been independently reviewed for this guide.

Housing & administrative law

Vacating an agency decision and granting Mitchell-Lama succession rights

Authored the New York County Supreme Court Article 78 decision

Waterman-Marshall vacated HPD’s determination and certificate of eviction, granted Kelvin Batts succession rights, and directed that an appropriate lease be provided.

The decision applied the Article 78 rational-basis standard and the rules for succession by a nontraditional family member in a Mitchell-Lama apartment.

Case context & history

The question: Did HPD act arbitrarily in denying a long-term partner’s succession claim?

Outcome / stage: Petition granted to the stated extent; certificate of eviction vacated and lease directed within 14 days of notice of entry.

The order reviewed an agency determination on the evidence in that proceeding. It did not create a general entitlement outside the governing succession rules.

Subsequent history: A targeted search of the New York Courts Reporter and First Department filings located no subsequent appellate disposition for this matter as of September 12, 2026; nonpublic docket activity is not included.

Matrimonial law, custody & support

After trial, Waterman-Marshall awarded the wife sole legal and residential custody with supervised parenting time, imputed $1 million annual income to the husband, set a $500,000 support and maintenance income cap, awarded maintenance and fees, and denied recusal. The First Department unanimously affirmed custody and most financial rulings, modified the counsel-fee award downward by $267,454.84, and dismissed a receivership appeal as moot.

What this tells you

This record shows both the trial court’s rulings and later appellate treatment, including a partial modification.

Outcome / stage: First Department affirmed custody and otherwise affirmed except for the counsel-fee reduction; receivership appeal dismissed as moot.

These are selected examples, not a complete review or a rating. A jury verdict, a party's allegation, and a judge's ruling are distinct. The candidate's role is identified for each example, and one case does not establish an overall judicial philosophy.
