These testimonials reflect the experiences and opinions of individual clients. Every case is different, and past results do not guarantee or predict a similar outcome in any future matter.

Strategic Legal Planning

Every matter begins with a clear-eyed assessment of your objectives and the realistic paths available under Virginia law to reach them.

Persuasive Advocacy

When negotiation and mediation reach their limits, disciplined, courtroom-tested advocacy protects what matters most to you and your family.

Client-Centered Representation

Your goals and circumstances, not a one-size-fits-all playbook, drive every strategic decision in your case.

How I Handle a Case

Start With the End in View

Most family law cases are decided by choices made in the first weeks. I identify early where your case is likely to end, then build every step toward that result.

1

Assess

We start with where you want to be and what stands in the way. I review the facts that will drive the outcome, identify the weaknesses in your position as well as the other side’s, and give you a realistic view of how the evidence is likely to look to a Fairfax or Loudoun judge. Immediate risks to support, custody, or control of assets are addressed first.

See the End Early

2

Set the Strategy Together

Your objectives define where we are going. My experience defines how we get there with the evidence we have and the evidence we can obtain: what must be secured first, whether temporary (pendente lite) relief is needed, discovery aimed at the issues that will decide the case, and the right experts when valuation, forensic accounting, or a custody evaluation is in play.

Your Objectives, My Experience

3

Negotiate from Strength

Most cases settle, and the ones that settle well were prepared for trial from the start. I negotiate with the trial already mapped out, and I tell you plainly whether an offer serves your objectives.

Leverage Built on Preparation

4

Try the Case

When an offer does not serve your objectives, the case goes to court: pendente lite hearings, discovery enforcement, expert testimony, and trial.

Ready for Trial

Every case turns on its own facts. These stages describe my approach, not a promised result.

Common Questions

Frequently Asked Questions

Before You File

If you share a computer or phone, save it somewhere private.

How long must we be separated before a divorce can be granted in Virginia?
A no-fault divorce from the bond of matrimony (a final divorce) requires one year of continuous separation without cohabitation. The period drops to six months if you have signed a separation agreement and there are no minor children. Va. Code § 20-91(A)(9)(a). Since July 1, 2026, either spouse may file for a divorce from bed and board as soon as the parties separate, provided at least one of them intends the separation to be permanent. Va. Code § 20-95. A bed and board decree does not end the marriage, and a final divorce is still subject to the separation periods above. Related: Changes to Virginia Divorce Law on July 1, 2026.
Does adultery still matter in a Virginia divorce?
Yes, but the 2026 amendments narrowed it. Adultery is now a ground for divorce only if it occurred before the parties’ last separation. Va. Code § 20-91(A)(1). Adultery can also affect spousal support. Permanent support is generally barred for a spouse against whom an adultery ground exists, unless the court finds by clear and convincing evidence that denying support would be a manifest injustice. Va. Code § 20-107.1(B). Whether to plead fault is a strategic decision, and it should be made early. Related: Repair or File? How Marital Conduct Affects a Virginia Divorce.
Is there a presumption of joint custody in Virginia?
No. The court may award joint legal, joint physical, or sole custody, but the statute provides that “there shall be no presumption in favor of any form of custody,” and no presumption in favor of either parent. Va. Code § 20-124.2(B). The decision rests on the child’s best interests, measured by the factors in § 20-124.3. Related: How Virginia Judges Decide Custody Cases.
What is pendente lite relief?
It is temporary relief ordered while the divorce is pending. Under Va. Code § 20-103, the court may address spousal and child support, custody, exclusive use of the family residence, payment of debts, and orders preserving either spouse’s estate. The pendente lite hearing is often the first contested hearing in a case, and its result can set the terms of everything that follows.
What should I bring to an initial consultation?
Bring whatever you have readily available: recent pay records, the last three years of tax returns, recent account and retirement statements, any agreement you or your spouse has signed (prenuptial, postnuptial, or separation), and any existing court orders. If a business is involved, bring its recent financial statements and tax returns. Incomplete records are common and are not a reason to delay the meeting.
