PRACTICE AREAS
Areas of Practice
Williamson Family Law handles the full range of family law matters in Texas.
Dissolution of Marriage
Comprehensive representation in contested and uncontested divorce matters. Mark Williamson brings four decades of courtroom and negotiation experience to bear on the outcome that matters most — a fair and final resolution.
Texas community property law governs the division of most marital assets. Mark’s approach is methodical: identify separate property, trace asset origins, evaluate tax consequences, and negotiate settlements that are structured to hold. When negotiation fails, he is fully prepared to litigate.
Property Division
Sophisticated analysis and advocacy in the division of complex marital estates — retirement accounts, real estate, business interests, investment portfolios, and mineral rights.
Proper division of retirement accounts requires a Qualified Domestic Relations Order (QDRO). Improper handling triggers taxes and penalties. Mark’s background in business and his U.S. Tax Court admission mean he addresses financial and tax dimensions that many family law attorneys refer out. He works with CDFAs and CPAs when complexity warrants.
Marital Property Agreements
Drafting and review of prenuptial and postnuptial agreements designed to withstand legal challenge and serve their intended purpose when called upon.
A marital property agreement is only as valuable as its enforceability. Mark drafts agreements that are properly executed, fully disclosed, clearly written, and structured to survive scrutiny. He also reviews agreements prepared elsewhere when clients require independent analysis before signing.
Modification & Enforcement
Representation in post-decree matters — modification of existing orders when circumstances have materially changed, and enforcement when compliance has lapsed.
A material and substantial change in circumstances is required to modify most Texas family law orders. Enforcement may involve contempt proceedings. Mark has handled both sides of these matters across Dallas-area courts for four decades.
Paternity
Establishment and contestation of paternity, with careful attention to the legal, financial, and parental rights implications involved.
Texas law provides multiple mechanisms for establishing paternity, including voluntary acknowledgment and court-ordered genetic testing. The consequences — for child support, inheritance, and parental rights — are significant and permanent.
Adoption
Legal representation through all stages of the adoption process, with an emphasis on efficiency, accuracy, and a straightforward path to finalization.
Texas adoption proceedings require termination of parental rights, compliance with statutory requirements, and court approval. Mark has guided families through stepparent adoptions, adult adoptions, and private placements with the thoroughness the process demands.
