Generally-speaking, the short answer is no. A Memorandum of Understanding outlines the intention of making a legal agreement, but it is not a legally enforceable document itself. While it is not enforceable, it is a powerful tool for helping you outline what the final, legal agreement will include. In most cases, unless money is exchanged an MOU will not stand up in court if challenged.
You may want to seek legal advice to help determine the enforceability of your Memorandum of Understanding.
