Why Do Cannabis Companies Need an Attorney?

Cannabis companies need an attorney for several reasons. Hiring a lawyer might seem to be an unnecessary expense for new businesses, but it can save you a lot of money and headache in the long run. Developing a relationship with an attorney at the start of your business can help you continue to build and improve in the years to come. 

Reason: Attorneys keep track of changes in cannabis policies and regulations. They can advise you of these changes and help you stay compliant. 

Reason: An attorney can help you protect your business’s intellectual property and trade secrets. 

Reason: By having an attorney lined up when you start your business, you’ll have someone to advise you on marketing regulations, customer relations and more. 

How to Make the Most of an Attorney on Retainer

In most cases, when you develop a relationship with an attorney, you will likely have the attorney on retainer. This means you’ll pay your attorney a fee (the retainer) up front to keep the attorney on call for services. When you have an ongoing relationship with your attorney, it’s important to know how to get the most out of your money. 

Tip: Keep your communication simple. When contacting your attorney regarding a question or an issue, you should only contact them once by either phone or email. Your attorney will charge for the time spent handling your matter, so if you call about an issue and then email to follow up, you are unnecessarily increasing your fees. You should also avoid talking to your attorney about unnecessary information so you’re only charged for what’s needed.

Tip: Know when to handle things on your own. You want to keep in communication with your attorney on an as-needed basis. This means that you should try to handle small, nonlegal matters on your own. For example, you do not need your attorney’s help when it comes to formulating your business plan. You can also handle registering your business name and applying for an employer identification number on your own. However, your attorney should be the one to handle contracts and agreements. 

Tip: Stick to your attorney’s schedule. Some attorneys may charge more for meetings after hours or on weekends. Be sure you understand your attorney’s office hours and retainer policy before setting up a meeting.

Tip: Use your paralegal when possible. Your retainer agreement should detail the fees for working with your paralegal as well as with your attorney. Paralegals can often handle day-to-day correspondence at a lower rate, so working with them can help you stretch your retainer. Your paralegal can also tell you when a matter should be handled by the attorney.

Tip: Send items to your attorney on time. When working with your attorney, you will likely need to provide documents and other information as needed. Make sure you respond to these requests in a timely manner. If you don’t, you can expect to be charged for follow-up reminder calls and emails.
