“He who is always his own counseller will often have a fool for his client.” [Source: Shapiro, “The Oxford Dictionary of American Legal Quotations,” citing Port Folio (Philadelphia, Aug. 1809, at 132.]
Not a day goes by when I don’t:
1) Read about someone who made a BIG mistake thinking s/he knew everything about drafting contracts, wills, and other legal documents.
2) Talk to a lawyer who is getting paid BIG bucks to fix the mistakes made by that “someone” in #1.
You can (or may be able to) represent yourself, but you have to do the work if you want to be more than The Fool. See, for example, this blog post about self-representation generally, landlord-tenant law specifically.
