Construction, Business & Real Estate Law Done Right

Our supervising attorney, Stephen Kitagawa, has successfully settled a complex, multimillion-dollar business dispute between family members, securing a far better outcome than expected. The settlement saved our clients over $700,000, bringing immense relief, especially to one elderly client, who can now enjoy his golden years in peace.

RECENT CASES

CONSTRUCTION LITIGATION

$2.8 MILLION

A client whose company worked as a subcontractor on a major construction project was sued by the general contractor for $2.8 million. The lawsuit included allegations of breach of contract and other business-related claims. The company owner was also sued personally, putting both his business and personal assets at risk.

BUSINESS LITIGATION

$1 MILLION

In a multimillion-dollar family business dispute, senior attorney Stephen Kitagawa negotiated a settlement that saved our clients more than $700,000. The resolution closed a difficult chapter for the family and allowed an elderly client to step away from the stress of ongoing litigation.

SETTLEMENT RATE

95%

We have a 95% settlement success rate. "In the courtroom, victory doesn’t go to the loudest voice, it goes to the sharpest mind and the most relentless advocate."

I had a very positive experience with Ghassemian Law Group while dealing with a sensitive business matter. I worked directly with the Managing Attorney, who was professional, knowledgeable, and took the time to provide sound legal advice along with various scenario options to consider. The staff were also responsive and genuinely friendly throughout the process. Overall, Ghassemian’s expert consultation gave me great peace of mind, and I highly recommend them.

This is not a boring and impersonal law office. Justin, the office manager, as well as several of the women, are so kind and caring, you forget you're speaking with a law office. They are extremely knowledgeable, as well. I really felt that Justin genuinely cares about this problem situation I'm experiencing with a contractor. They do not want to take your money, for nothing and will only have your best interest in mind. The amount of resource that Justin was simply out of the kindness of his heart as I have not retained this office was amazing. Particularly considering the climate of 2025 and everybody is only worried about themselves. I strongly recommend this Law firm for all of your complicated situations with contractors and any other service they provide. You have a friend at Ghassemian Law group.

Mission Viejo, California, United States

All of Ghassemian Law Group’s attorneys have a minimum of 25 years of litigation experience.

Transaction Law

Transaction Law focuses on the buying, selling, and leasing of property. Real estate transaction attorneys handle purchase agreements, title searches, deed preparation, closing documents, and ensure a clean transfer of ownership. They review contracts, negotiate terms, resolve title issues, and make sure financing arrangements comply with regulations. This is preventative law, structuring deals properly to avoid future disputes.

Litigation Law

Litigation Law deals with disputes and lawsuits involving property. Real estate litigators represent clients in court on boundary disputes, breach-of-contract claims, landlord-tenant conflicts, construction defects, easement rights, zoning challenges, and foreclosure defense. They handle cases when transactions go wrong, when parties disagree over property rights, or when someone has been harmed by another’s actions related to real estate.

Investment Law

Covers the legal aspects of using real estate as an investment vehicle. This includes structuring syndications, real estate investment trusts (REITs), 1031 exchanges, joint ventures, and other investment partnerships. Investment attorneys handle securities compliance, tax planning, entity formation, private placement memoranda, and ensure investment structures comply with both real estate and securities regulations. This area blends real estate law with corporate, tax, and securities law.

Mission Viejo, California, United States

Frequently Asked Questions

While not legally required in most states, having a real estate attorney is highly recommended. They review purchase agreements, identify problematic contract terms, conduct title searches to ensure there are no liens or ownership disputes, and handle closing documents. In complex transactions—like commercial purchases, properties with easements, or deals involving multiple parties—an attorney can prevent costly mistakes. The relatively small upfront cost of legal counsel often saves thousands in avoided problems down the road.

A real estate agent helps you find properties, market your home, negotiate offers, and guides you through the buying or selling process—but they cannot provide legal advice or represent your legal interests. A real estate attorney reviews and drafts contracts, ensures legal compliance, resolves title issues, represents you in disputes, and protects your legal rights throughout the transaction. Many people work with both: an agent to navigate the market and an attorney to handle the legal aspects.

The best structure depends on your specific situation, including liability concerns, tax considerations, number of owners, and future plans. An LLC offers liability protection with simpler management and pass-through taxation. A corporation provides the strongest liability shield and is better for raising investment capital, but involves more formalities and potential double taxation (unless you elect S-corp status). Partnerships are simpler but offer less liability protection. A business attorney can analyze your needs and recommend the structure that best protects your interests while minimizing tax burden.

Always. Even for small transactions, written contracts protect both parties by clearly defining expectations, deliverables, timelines, payment terms, and what happens if something goes wrong. Verbal agreements are difficult to prove and enforce. Standard contracts or terms of service should be in place before you provide goods or services. For larger deals or unusual arrangements, have an attorney draft or review agreements to ensure they’re enforceable and protect your interests.

The terms are often used interchangeably, but “business lawyer” is broader—covering legal issues for all types of businesses including sole proprietorships, partnerships, and LLCs. They handle contracts, employment issues, regulatory compliance, and general business matters. “Corporate lawyer” typically refers specifically to attorneys who work with corporations, focusing on corporate governance, securities, mergers and acquisitions, and shareholder issues. Small businesses usually need a business lawyer, while larger companies or those seeking investment often require corporate legal expertise.
