There is no easy answer as to whether you require professional legal representation. Every individual is different and has different skills, experience and expertise. A person should never undertake significant legal or financial obligations unless that person understands the transaction and the consequences of their actions and has made the appropriate informed decision. As a general principle, a lawyer should always be consulted before an individual or company executes significant legal documents (like a deed, will or contract) to ensure that they understand the potential legal ramifications of the document and to ensure that the transaction is understood and in the client's best interests.
