Gay and Lesbian Family Law Attorney in Manhattan, New York

New York has long stood at the forefront of LGBTQ legal equality, and Steven J. Mandel has represented LGBTQ clients across this borough through every phase of that movement — from a period when same-sex relationships carried no legal recognition at all, to today’s landscape of full marriage equality under state and federal law. That history shapes how we handle LGBTQ family law matters now, particularly for clients whose relationships span both eras.

Full legal equality hasn’t eliminated the practical complexity. Relationships that predate marriage rights, children born or adopted under varying legal frameworks at the time, and assets built together without the protections formal marriage would have provided all require an attorney who understands not just the current law, but how it got here — and who won’t need the history explained to them before the legal strategy can even begin.

LGBTQIA+ Divorce in Manhattan, New York

Same-sex divorce in New York is governed by the same statutes and procedures as any other divorce, but unique practical complications can still arise — particularly when a couple’s relationship began years before their marriage was legally possible, complicating how courts value marital versus separate property accumulated during that earlier period of the relationship. Determining exactly when a couple’s economic partnership began, as opposed to when the marriage itself was legally recognized, can materially change how assets are classified and divided, and a spouse who contributed years of unrecognized partnership before the wedding date deserves an advocate who will make that argument forcefully rather than accepting the marriage date as the only relevant starting point. We handle same-sex divorce} throughout Manhattan with an understanding of these timeline issues that a generalist family law practice often misses entirely.

LGBTQIA+ Child Custody Rights in New York County

Non-biological parents in LGBTQ families can face custody standing questions that biological or adoptive parents never encounter, particularly when second-parent adoption or a formal donor agreement was never completed at the time a child was born or adopted. Establishing parentage early — well before any custody dispute arises — is the single most effective way to prevent this vulnerability, since courts still sometimes struggle to apply established doctrine consistently in contested cases, and a parent who has functioned as a full parent for years can still face an uphill fight without the paperwork to back it up. We help LGBTQ parents throughout this borough secure that legal footing proactively, and litigate custody rights vigorously when the issue wasn’t addressed in time, drawing on decades of experience with exactly this kind of dispute.

LGBTQIA+ Life and Estate Planning in Manhattan

Marriage equality didn’t eliminate the need for careful estate planning — a will, power of attorney, and health care proxy remain essential documents for protecting a spouse and any non-biological children from a family challenge after death or incapacity, particularly when a client’s family of origin has not fully accepted the marriage or the children within it. Without these documents in place, a surviving spouse or a non-biological child can face disputes over inheritance, medical decision-making, or even funeral arrangements that formal marriage alone doesn’t fully prevent, and hospital visitation rights that most married couples take for granted can be contested in the absence of a properly executed health care proxy. We help LGBTQ families throughout the city put these protections in place before they’re needed, not after a crisis makes them urgent and the window for careful planning has already closed.

Domestic Partnership and Cohabitation Agreements

Couples who choose not to marry, or who built significant assets together during a relationship’s pre-marriage-equality years, occupy a legal gap that a cohabitation agreement is designed to fill — addressing property division, support, and other financial terms that New York law wouldn’t otherwise provide for an unmarried couple. These agreements need the same careful drafting as a prenuptial agreement to be enforceable, and courts will scrutinize whether both parties had independent counsel and full financial disclosure before signing, which makes a rushed or one-sided draft a real liability if the relationship later ends in dispute. We draft cohabitation and domestic partnership agreements for couples throughout Manhattan at every stage of a relationship, whether newly committed or decades in, revisiting the terms as circumstances change.

LGBTQIA+ Prenuptial Agreements in Manhattan

For LGBTQ couples with a long pre-marriage relationship history, a prenuptial agreement often needs to address assets built together before marriage became legally available — a complication most prenuptial templates were never designed to handle, since they generally assume the relationship and the marriage began at the same time. New York General Obligations Law requires these agreements to be in writing and properly acknowledged to be enforceable, regardless of how long the underlying relationship predates the marriage itself, and a poorly drafted agreement that ignores this history can end up doing more harm than having no agreement at all. We draft prenuptial agreements for LGBTQ couples throughout New York County that account for this history rather than treating the relationship as though it began at the wedding.

Frequently Asked Questions

Are same-sex divorces treated differently from other divorces in New York?

Does a non-biological parent have custody rights in New York?

A non-biological parent can establish custody standing, but the strength of that claim depends heavily on whether second-parent adoption or a formal parentage agreement was completed. Steven J. Mandel helps LGBTQ parents throughout Manhattan secure this legal footing before a custody dispute makes it urgent.

Why do LGBTQ couples still need estate planning after marriage equality?

Marriage doesn’t automatically resolve every question a will, power of attorney, and health care proxy address, particularly for protecting non-biological children or a spouse from a family challenge after death or incapacity. These documents remain essential regardless of marital status.

What can an LGBTQ prenuptial agreement cover in New York?

An LGBTQ prenuptial agreement can address property division, spousal support, and — importantly for many long-term couples — how assets accumulated before marriage became legally available will be treated. It must be in writing and properly acknowledged under New York law to be enforceable.

How does New York protect non-biological parents in same-sex families?

New York allows second-parent adoption and recognizes parentage agreements that establish a non-biological parent’s legal relationship to a child. Steven J. Mandel represents LGBTQ families throughout Manhattan completing these protections proactively, before any dispute arises.
