Your Operating Agreement Should Be Too.

Protect Your New Business with Custom LLC Formation & Operating Agreements from an Experienced Attorney

Invest in a Strong Foundation

You are starting a business because your idea, team or process will bring something completely new and valuable into the marketplace. Why would you assume that recycled boilerplate formation documents are enough to protect that unique intellectual property or define your partnership responsibilities and equity split? Custom business agreements are a vital investment in the future of your business.

While it may seem tempting to use generic templates or put off drafting your legal documents to save money in the short term, doing so can lead to costly legal disputes and liability down the road.

Taking a little extra time to work with our experienced attorneys and create custom business formation documents and agreements that are tailored to your unique business, stakeholders, and circumstances will prevent future legal headaches and protect your business from unnecessary liabilities.

In the long run, paying for custom business agreements at the beginning of your venture is far less expensive than facing costly litigation or disputes in the future.

I trust and highly recommend Bill Fillmore of Fillmore Spencer Law. Bill set up the US entity of our company, headquartered in Geneva Switzerland. He designed our executive structure and operating rules. He created all of our legal documents from consultant contracts to employment contracts and helped us attain our legal entity, company name and trademark registrations.

Working with Fillmore Spencer was my very first experience working with any type of legal team. I was purchasing a multimillion dollar business and had no clue as to how to do it! Bill and his team were patient and explained everything, no matter how mundane it might have seemed, to make sure I completely understood what was going on. Bill made sure that all the documents involved in the purchase were fair and even, which is exactly what you should look for in a lawyer! It was a pleasure working with him and his team!
