About Seeley & Madigan, LLP

We are a boutique family law firm based in San Mateo with an impressive record of courtroom victories and negotiated settlements.  With 40 years of collective litigation experience, we provide clients living on the Peninsula and in the greater San Francisco Bay Area with exceptional legal representation in family law matters, from the most straightforward and uncontested to the most complex and contentious. 

At Seeley & Madigan, LLP, we will work closely with you to determine which dispute resolution process is the most efficient for your case, including negotiation for out-of-court settlement, collaborative law, mediation, litigation in public court or with a private judge.

We have extensive experience with complex and high-conflict dissolution cases and collaborate with other professionals, including forensic accountants, business valuators, and child development specialists, when appropriate.


H. Yvonne Seeley, a certified family law specialist, has been recognized for her advocacy skills at both the county and the state level.  We encourage the use of mediation to amicably resolve family law disputes wherever possible.  However, when litigation is unavoidable the attorneys at Seeley & Madigan, LLP will never hesitate to go to court to advocate for your best interests.


We recognize that going through a divorce is one of the most difficult issues many of our clients will face.  Decisions you make during the process can have a lasting impact on your family, your assets, and your finances.  Our qualified family law attorneys will educate you about the legal process and help you make informed decisions about your case.  No matter the scope of your case, our team will work tirelessly to protect your rights and ensure that all agreements, property divisions, and custody arrangements are fair to you and your children.


We use a team approach, delegating work when appropriate, which ensures that your case will be handled economically.  And, unlike larger firms, we are flexible with respect to billing arrangements. We will work closely with you, keeping you apprised of the developments in your case and giving you cost-savings options whenever possible.


We know that the most successful settlements come from intense trial preparation.  Accordingly, for those cases that are contested and headed for trial, we prepare them thoroughly.  Should negotiations break down at any point, we will be ready.  Our attorneys are experienced civil litigators.  H. Yvonne Seeley spent several years conducting civil jury trials and appeals before transitioning to family law.  We believe that this experience gives us a clear advantage, as we have a depth of knowledge of trial strategy, discovery, rules of evidence, and civil procedure that is uncommon for the family law setting.
