You’re not legally bound to have an attorney, but it might be in your company’s best interest to have one creating your contracts. If you don’t have a lot of experience writing them, you might miss important details, and the other parties you’re conducting business with can easily find loopholes if they no longer wish to fulfill their end of the bargain.

If you run a business, you’ll need a contract more often than you think. You need one for your vendor agreements, lease agreements, transportation agreements, shareholder rights, stock options, employee policies, mergers, acquisitions, etc. A well-written contract prevents any ambiguity and protects you from legal action other parties might take.

Most importantly, you could use the time to attend to more important business matters instead of stressing about what should be included in your contracts. Check out ChauvelLaw.com for more info.

I was wondering the same thing not long ago. The short answer is no; no law states that contracts are only valid if an attorney is involved. And for most everyday business needs, a small business can meet its contract needs by modifying existing templates for different purposes.
That said, there are still good reasons to get a contract lawyer San Francisco involved in the process at some point. If having an attorney draft every new contract isn’t feasible, you can at least have a law firm like The Law Offices of Ara Jabagchourian audit your contracts once a year or so to help iron out any issues in your existing contracts.
After all, the main purpose of a written contract is to remove ambiguity and prevent conflict between both parties that have entered the agreement. And if you don’t work to make sure the language on your contracts is sufficiently clear — and to make sure the terms of the contract are legal — you run the risk of facing legal action from a business partner in the future.
