While most are not legally binding, there may still be consequences for not complying with the agreed upon portions of the letter. A Letter of Intent is often seen like purchase or crowd-sourced orders, so they are often used to help secure funding or prove the value of the business. If the other party drops out or doesn't honor "in good faith" the letter, actual financial damage may be incurred to the company. In court, most often the judge will make decisions based on what implied intent is expressed in the letter. Sometimes there can be recourse if the parties do not follow through towards an actual legal agreement.
By now, you probably think you're familiar with all the pieces of an application package and process. You have your resume (or CV), your cover letter, your list of interview questions. And if you have those together, updated and ready to go, awesome! But there's another potential piece lurking out there: a letter of intent. Wait, what? Is that the same as a cover letter? And if not, how do you write one?
