William Kirby Law

Focus and practice areas

William Kirby Law describes itself as a boutique family law firm practicing matrimonial law. That description matches what the site actually shows. Every listed service sits inside family law, and the menu carries no unrelated categories.

Divorce anchors the work. The firm lists several forms of it: military divorce, same-sex divorce, and uncontested divorce. Divorce mediation appears as its own listed service.

Beyond divorce, the firm handles child custody and visitation, child support, spousal support, and paternity. It also takes post judgment modifications, property division, and separation agreements. In my opinion, that last group tells a reader something useful. Post judgment modification work means the firm keeps files open after a decree, and clients who need a support order changed years later have somewhere to go.

How the team is built

The site names three attorneys. William Kirby is the managing attorney. Valerie Newcomb is a senior attorney, and Leah Roos is a family law attorney.

William Kirby

Kirby leads the firm. The site notes 21 years of experience as a Marine. Military service reads differently in a practice that lists military divorce as a service area, since those cases involve retirement pay division, service member protections, and custody questions shaped by deployment.

Valerie Newcomb

Newcomb is based in Mount Laurel and has the fullest biography on the site. She graduated from Delaware Law School of Widener University. After law school she clerked for a judge of the Superior Court of New Jersey, Chancery Division, Family Part.

That clerkship is the detail I would flag to a prospective client. Family Part is the New Jersey court where divorce and custody matters are decided. A lawyer who spent a year inside that chamber has watched judges weigh the same arguments she now makes.

In 2009 Newcomb founded Spino and Newcomb, LLC. She ran it as managing attorney for close to 15 years before joining her current firm. A lawyer who built and operated her own family law practice for that long brings a settled sense of how these cases move.

Support staff

The site names five people in paralegal and staff roles: Denise Moorhouse, Regina O'Brien, Roxann Navarra, David Montero, and Amanda Robinson. Naming support staff on a public page is a choice worth noting. Family law runs on document handling, and the people who assemble financial records often have more client contact than the attorneys do.

Where the firm practices

William Kirby Law works across two states. The main office is in Mount Laurel, New Jersey. A second office operates in Philadelphia, Pennsylvania.

On the New Jersey side, the firm serves Burlington, Camden, Cumberland, Gloucester, and Mercer Counties. That covers a wide stretch of the state's southern and central regions. Pennsylvania coverage runs across Philadelphia, Delaware, and Montgomery Counties.

The two-state footprint carries practical weight in this corner of the country. Couples in the Philadelphia area often live and work on opposite sides of the Delaware River. Jurisdiction becomes a live question when one spouse stays in the city and the other moves to a New Jersey suburb. A firm licensed and staffed in both states can answer that question without a referral.

What the site explains about process

The firm's pages walk through the Pennsylvania divorce sequence. They describe filing the initial complaint in the Court of Common Pleas, then negotiations, conferences, and hearings.

The site also covers document gathering. It points clients toward income statements, tax returns, and documentation of marital assets and debts. This is the unglamorous engine of a divorce case, and firms that explain it up front tend to be firms that have watched clients arrive unprepared.

As a reviewer, I read this material as a signal about how the firm communicates. Publishing a procedural walkthrough takes effort that produces no direct marketing return. It helps someone decide whether they need a lawyer at all.

Reading the record

Some things a careful reader will want are absent from the public site. The firm publishes no founding year and no formal entity name. Law schools and bar admission years appear for Newcomb alone. Roos is named with her title and no biography. The site shows a "Follow Us" label with no social media links behind it, and no email address is published.

Those gaps limit what an outside reviewer can verify. They also shape how a prospective client should approach a first conversation. Anyone weighing this firm can ask directly about bar admissions, years in practice, and which attorney would handle their file.

What the site does establish is coherent. A boutique family law firm with three attorneys and five named support staff is a small operation by design. The service list stays inside matrimonial law. The geographic reach is specific and named county by county. The one attorney biography the site develops in full describes a clerkship in the exact court where the firm's New Jersey cases land, followed by 15 years running a family law practice.

Who this firm fits

The two-state licensing matters most to people whose marriage straddles the river. A Philadelphia resident divorcing a spouse who moved to Cherry Hill needs a firm that can read both court systems.

Military families are a second group the service list speaks to. Military divorce appears as a named practice area, and the managing attorney spent 21 years in the Marines. That combination is uncommon in a three-attorney family law office.

The firm's inclusion of same-sex divorce and uncontested divorce as separate listings suggests attention to how differently these cases run. An uncontested matter needs efficient paperwork. A same-sex divorce can raise questions about relationship start dates that predate marriage equality, which affects property division and support calculations.

For someone in South Jersey or the Philadelphia suburbs facing a custody dispute, a support modification, or a divorce, William Kirby Law offers a small team working entirely within family law across both states. The site names its attorneys, names its staff, names its counties, and explains its process.
