About Keystone
For sixteen years, we've done one thing:
turn complex law into something you can make decisions with.
The law shouldn't be a wall that makes you back down. We believe good legal service means putting expertise into plain language, laying the risks out in the open, and letting you make every decision with the full picture in hand.
Practice areas

Whether it's corporate governance, a commercial dispute, or family and estate planning, you'll find the right expertise here—and it's all one team.

We guide companies through both everyday legal needs and pivotal transactions, turning legal risk into manageable decisions — from startup formation and equity structuring to cross-border M&A, always balancing commercial goals with compliance.

Litigation & Disputes
When disputes arise, we weigh the real cost of litigation against settlement before setting strategy — representing clients in contract, debt, tort, and commercial disputes before courts at every level and in arbitration.

Family matters are about people and emotions as much as law. With empathy and professionalism, we handle divorce, custody, asset division, and estate planning — minimizing conflict and protecting your long-term interests.

Real Estate & Construction
Real estate deals are large and long, and the details decide the outcome. We support sales, leasing, development, and construction matters — from contract diligence to dispute resolution — safeguarding your assets.

Intellectual Property
From trademarks and patents to trade secrets, IP is a modern company’s core asset. We help you build, license, and enforce your portfolio — and act decisively when infringement occurs.

Labor & Employment
Labor law changes fast and penalties are steep. We help employers build lawful, workable HR policies — and represent both employers and employees in negotiation and litigation when disputes arise.

What clients say
Trust is the case that matters most
During the two tensest weeks of the merger talks, Lin’s team was there almost around the clock. They didn’t just read the clauses — they understood what we actually wanted, and held the line on the terms that mattered.
I assumed we had to go to court, but Chen first laid out the real costs and odds. We settled through mediation — and the time and peace of mind we saved mattered even more than the money.
Settling my father’s estate put real strain on the family. Wang was patient, separating the law from the emotions, and we came through it without burning any bridges.
As a startup, our biggest fear was that legal would become a brake. Chang understands tech — there was zero communication gap — and he laid out our patent strategy and employee equity cleanly.
Legal insights
Practical legal perspectives
Common legal questions, explained in a way that actually makes sense.
Five things to check before you sign a contract
Most commercial disputes are seeded the moment a contract is signed. Here are the five clauses most often overlooked — and most likely to cause trouble.
Do you really have to sue? The real value of mediation
Litigation isn’t the only path — and sometimes not the best one. We weigh mediation across three dimensions: cost, time, and relationships.
Estate planning isn’t just for the wealthy
Wills, trusts, and insurance planning aren’t really about saving tax — they’re about leaving the people you love with less conflict and more peace when you’re gone.
