During her legal career, Sonja Aoun has developed extensive experience in the field of family law. She has now added estate planning to further help families protect their loved ones. For over twenty years, she has helped families throughout Virginia resolve their legal matters and obtain peace of mind during some of life’s most difficult times.

Ms. Aoun has earned the respect of clients and colleagues alike for her creative problem-solving, her effective trial advocacy, and the informed, compassionate, and ethical approach she brings to family and estate matters. She has a passion for helping families with a special commitment to finding solutions for children with special needs.

Her practice addresses all aspects of family law including separation agreements, divorce, custody, visitation, property division, child support, spousal support/alimony, premarital settlement agreements, post-nuptial agreements, enforcement of agreements, modification of orders, stepparent adoptions and adoptions of adult children. She has the experience and knowledge to effectively handle these matters from their inception through negotiation, mediation, trial, and appeal, as necessary.

Ms. Aoun is skilled in handling complex and highly nuanced divorce and custody cases involving post-traumatic stress disorder, narcissistic personality disorder, and high conflict personalities. She has helped military families, state department families, and others facing relocation. She works with special needs families, blended families, LGBTQ families, high net worth families, and families with closely held businesses.

Ms. Aoun works with experts in the fields of real estate, special education, financial planning, vocational rehabilitation, immigration, and mental health to ensure her clients receive the best possible outcome.

Recognizing that the need for planning extends well beyond marriage and children, Ms. Aoun has added estate planning to her practice. She prepares wills, powers of attorney, advance medical directives, and trusts to preserve her clients’ wealth and ensure that their families are well-cared-for. Through appropriate planning, Ms. Aoun helps her clients avoid tax liability, probate, and other unnecessary governmental involvement in their estates. As part of her estate planning practice, Ms. Aoun emphasizes planning for the future care of her clients’ children, particularly those with special needs. For many families, arranging trusts, guardianships, and conservatorships is essential to safeguard their loved ones’ futures. In such circumstances, Ms. Aoun provides careful guidance.
