John J. Kappel, Double Board Certified Family Law and Appellate Attorney at Goranson Bain Ausley's Plano office

About John J. Kappel

John J. Kappel is a partner in Goranson Bain Ausley’s Plano office and a Board Certified family and appellate lawyer. He represents business owners, executives, and professionals in divorce and custody matters — often when significant assets, a family business, or their children’s future is at stake. He is one of only 11 attorneys in Texas certified by the Texas Board of Legal Specialization in both Family Law and Civil Appellate Law. That rare pairing means a single lawyer’s strategy can run from the first hearing through a final appeal.

Much of John’s work involves the financial complexity that defines high-asset divorce: characterizing and dividing separate and community property, valuing closely held businesses, and resolving reimbursement claims. He also represents clients in international and cross-border matters, including custody disputes and cases of international child abduction under the Hague Convention — work that has taken him into both state and federal courts. That depth of experience has earned the confidence not only of clients, but also of attorneys in other states and countries who retain him as an expert witness on Texas family law issues. 

John approaches every case with the discipline of both a trial lawyer and an appellate lawyer. From the outset, he develops strategy with an eye toward the legal and factual issues that could shape the outcome long after the first hearing, building a strong record and positioning his clients for success whether a case is resolved through negotiation, trial, or appeal. He seeks resolution where it serves his clients and prepares thoroughly for trial when a case has to be decided in court. Throughout, he gives candid, straightforward advice so clients can make confident decisions and move through hard moments with clarity, discretion, and respect. 

What Sets Him Apart

  • Double Board Certified in Family Law and Appeals. John is among just 11 Texas attorneys certified in both fields by the Texas Board of Legal Specialization. The distinction reflects substantial experience and demonstrated skill on both sides of his practice.
  • Seamless Representation From Trial Through Appeal. John can try a case and handle any appeal himself, without handing it to separate counsel. Thinking ahead to appeal from the outset, he builds a record designed to hold up on review.
  • International and Hague Convention Experience. John represents parents in cross-border custody disputes and international child-abduction cases in federal court. His work produced the Fifth Circuit’s first application of the “totality of the circumstances” test for habitual residence.
  • Depth in Complex Property and Financial Matters. He handles property characterization and division, business valuations, and reimbursement claims in high-asset divorces. These matters call for detailed financial analysis and careful strategy.
  • Fellow of the American Academy of Matrimonial Lawyers. John is recognized as an AAML Fellow and is a certified arbitrator through the academy. Both mark peer recognition among experienced matrimonial attorneys.
  • A Contributor to Texas Family Law. John speaks regularly at statewide continuing legal education programs and writes for bar publications. His subjects include appellate practice, marital property, and Hague Convention litigation.
  • Expert Witness on Texas Family Law. Attorneys in other states and countries retain John as an expert witness on Texas family law issues, particularly in interstate and international disputes. His experience in appellate practice, international family law, and complex jurisdictional issues makes him a trusted resource for lawyers handling cases that intersect with Texas law. 

Practice Focus

John concentrates on the matters where appellate insight, financial complexity, or cross-border issues change the outcome:

  • Family Law/Divorce Appeals. Board Certified in civil appellate law, John prosecutes and defends family law appeals in the Texas courts of appeals. Appeals are central to his practice, not an occasional add-on.
  • International & Cross-Border Divorce. John handles divorce and custody disputes that cross international borders, including child-abduction cases under the Hague Convention, which he has litigated in federal court.
  • High Net Worth Divorce. John concentrates on the property side of high-asset divorce. He characterizes and traces separate and community property and resolves the reimbursement claims these estates commonly raise.
  • Divorce for Business Owners. When a business owner divorces, John works to divide the company fairly while protecting its operations and value.
  • Business Valuation in Divorce. He addresses what a closely held business is worth — often the most contested number in a high-asset divorce.
  • Child Custody. John represents parents in contested custody and modification cases, including those with international or multijurisdictional complications. Many reach the appellate courts.
  • Litigation. When a matter must be resolved in the courtroom, John prepares it thoroughly and builds a clean record around the issues that would matter most if the case is later challenged.
