Family Law

Protecting your rights and your family’s best interests

Every family is different. Every situation is unique. Divorce, custody, and support issues are stressful for everyone, including children. We’ll be with you every step of the way to help you make informed decisions that are right for you and your family. At Kay Mahoney Koustov Law, we have the experience and skill to guide you through the process of your separation, make sure you understand all your options, and manage the relationship with the other side’s lawyer. Our goal is to get to a fair resolution as amicably as possible so you can get on with your life.

The lawyers in our group focus exclusively on family law, and we can help you with:




Child custody


Child support


Cohabitation agreements


Common law separation




Prenuptial agreements


Postnuptial agreements


Shared parenting


Sole custody


Spousal or partner support

We know how to choose the right tactics for your situation. If we need a mediator, we’ll select one based on your case. We also have strong, well-established connections with experts, including psychologists, accountants, business and pension evaluators, and parenting consultants.

A firm, but civil approach

We focus on solutions, which means protecting your best interests and reaching a fair settlement. Keeping a good working relationship with the other party helps us avoid unnecessary costs and disputes. We strongly believe in a proactive and cooperative approach to cases, which is why we:


make sure we’re prepared better and earlier


are diligent in applying legislation and current case law


use our time productively and effectively


stay objective and practical

Keeping costs under control

You’re already dealing with a lot, and worrying about legal fees is the last thing you need. We start by weighing costs against benefits and continue to do this at every step of the process. Because we assign tasks to the right people at the right seniority and skill level, you aren’t paying higher fees unnecessarily.

We also don’t have to go outside the firm to access lawyers in related areas. We’ll consult colleagues in our Real Estate, Wills, Trusts & Estates, and Business groups to make sure your needs are covered.
