Using the medium of an invoice The person who supports an invoice A person or company that supports someone Many jurisdictions have completely eliminated support sheets and instead require that the name, address, and phone number of the issuing lawyer or law firm be included in the legal document itself, usually under the lawyer`s signature pad. The supporting sheet is the back cover of a legal document. It is designed to show when folded what the legal document is and who it comes from. Supporting documents are preferred by litigation servers and Court Registry staff. The supporting sheets have the title of the document in the middle part and the name and address of the law firm are indicated at the bottom of the back sheet. Lawyers still use supporting sheets for documents such as wills or powers of attorney because folding protects the contents of the document.
